Add Magnetic Holding Power to Bits & Hand Tools
Dropped screws slow down more than the fastening job—they interrupt positioning, alignment & one-handed installation. The Hobson | Magnet Booster is a compact magnetic accessory designed to add magnetic holding assistance to compatible screwdriver bits, while Hobson also documents its use with hex keys & screwdrivers. For trades working with repetitive screw installation, awkward starting positions or small fasteners, it provides a simple way to improve control without changing the fastener itself.
Part of Hobson's DRILLX® drive-bit offering, the TXDMB Magnet Booster sits naturally alongside Hobson | Sockets & Bits, Drill Accessories & Hobson | Screws. That connection matters when buyers are assembling a complete fastening setup rather than purchasing an isolated accessory.
What Is the Hobson Magnet Booster?
Think of the Magnet Booster as a small addition that changes how easily the driver & fastener can be controlled. Hobson identifies product code TXDMB as a 1/4 drive-bit Magnet Booster within its DRILLX® range, with manufacturer guidance showing it being added to a screwdriver bit to increase magnetic holding assistance.
Its usefulness is not restricted to one type of driver accessory. Hobson also documents compatibility with hex keys & screwdrivers, making the Magnet Booster relevant to workshop, installation, assembly & maintenance tasks where retaining a small ferrous fastener at the tool tip can make positioning easier.
Unlike a magnetic nut setter, the Magnet Booster is an accessory used with an existing compatible tool or bit. Buyers should therefore distinguish between adding magnetic assistance to a driver & purchasing a dedicated magnetic driving accessory.
Why Choose the Hobson Magnet Booster?
Ever tried starting a screw where your second hand simply cannot reach? That is the type of fastening problem a magnetic booster is designed to address.
By helping a compatible tool retain a ferrous fastener, the Magnet Booster can make initial positioning more manageable before the screw engages the workpiece. This can be particularly useful around cabinetry, brackets, sheet-metal assemblies, equipment panels & other locations where access makes two-handed screw starting inconvenient.
Product simplicity is another advantage. Rather than changing an entire driver setup for occasional magnetic retention, the TXDMB provides a compact accessory that can be introduced when the task calls for it.
For buyers reviewing the wider relationship between driver accessories & the fastener itself, Why Good Fasteners Matter More Than the Tool You Drive Them With provides useful additional context.
Common Applications
Repetitive Screw Installation
Hundreds of small fastening movements can turn a minor handling improvement into a meaningful workflow advantage.
During repetitive assembly, keeping the screw positioned at the driver tip can reduce unnecessary handling between picking up the fastener & presenting it to the workpiece. The benefit becomes especially noticeable when screws are being installed above shoulder height, inside assemblies or across repeated fixing points.
Where the job also requires powered driving equipment, Impact Drivers provides a relevant pathway into the broader fastening setup.
Restricted-Access Fastening
Access often determines whether a simple screw becomes an awkward installation.
Inside cabinets, housings, machinery, brackets or fabricated assemblies, there may be room for the screwdriver or bit but little space for fingers to steady the fastener. Magnetic assistance can help retain a compatible ferrous screw during that initial approach.
Before assuming magnetism solves every access problem, confirm that the selected bit, driver & fastener remain appropriate for the installation.
Workshop Assembly & Maintenance
Small components have a habit of disappearing exactly when equipment is already apart.
For workshop technicians, maintenance teams & fabricators, magnetic holding assistance can make screw removal & refitting more controlled where suitable ferrous hardware is involved. It can also be useful when working around guards, covers, panels & equipment housings.
A cleaner, organised tool setup supports the same objective. Tool Maintenance Kit provides a related pathway for crews maintaining frequently used tools & accessories.
Hex-Key Tasks
Socket-head fasteners introduce a different driver shape, but the handling problem can be remarkably similar.
Hobson specifically notes that the Magnet Booster also suits hex keys, extending its usefulness beyond conventional screwdriver bits. This can assist with compatible ferrous socket-head hardware where holding the fastener at the tool during initial positioning is useful.

Mobile Trade & Installation Work
A compact accessory earns its place in the tool kit when it solves the same small frustration across multiple jobs.
Electricians, installers, maintenance technicians, fabricators & general trades may encounter different fastening situations throughout a day. Keeping the Magnet Booster with commonly used driver accessories gives crews another option when screw retention becomes useful on site.
Product Selection Guide
Start With the Tool You Intend to Use
The first question isn't “How strong is the magnet?”—it's “What am I trying to magnetise?”
Hobson documents the TXDMB Magnet Booster for use with a screwdriver bit & also states that it suits hex keys & screwdrivers. Confirm that the intended tool or accessory can be used with the booster as designed before relying on it for the task.
If the fastening setup itself needs to change, Power Tools provides a broader route into powered equipment rather than expecting a magnetic accessory to compensate for an unsuitable driver.
Check the Fastener Material
Magnetic assistance depends on the fastener responding to the magnetic field.
A Magnet Booster should not be expected to retain every screw, bolt or component simply because the tool has become magnetised. Fastener material & magnetic response matter, so test the actual hardware where retention is important to the workflow.
This distinction is particularly relevant when a workshop uses several fastener materials across similar-looking components.
Separate Retention From Driving Performance
Holding the screw & driving the screw are two different jobs.
The Magnet Booster can assist with magnetic retention, but it does not change whether the bit profile correctly matches the screw recess. Phillips, hex, square, Torx & other drive forms still require the correct corresponding driver.
A poorly matched bit can damage the fastener regardless of how conveniently the screw remains attached to the tool.
Match the Driver to the Fastener
Good retention cannot rescue the wrong drive profile.
Before starting repetitive work, confirm the screw recess, bit type, bit condition & driver setup. Hobson's broader drive-bit range includes Phillips, hex, square, Torx, slotted, trilobular & other configurations, reinforcing why the Magnet Booster should be treated as one part of the complete fastening system.
Where replacement or additional hardware is required, Bolts & Fasteners provides access to wider fastening options.
Decide Whether a Booster or Dedicated Magnetic Accessory Makes More Sense
Not every magnetic fastening task calls for the same solution.
Hobson lists the Magnet Booster alongside dedicated drive accessories such as magnetic nut setters. A booster can make sense where magnetic assistance needs to be added to a compatible existing tool, while a dedicated magnetic accessory may better suit work centred on a particular fastener or drive style.
Choose according to the fastening operation rather than assuming all magnetic accessories perform the same role.
Choosing the Right Setup Around a Magnet Booster
The Magnet Booster is most useful when every component around it is already doing the correct job.

Expert Tips
Test the Actual Screw Before Starting a Batch
One quick trial can prevent discovering halfway through the job that the fastener does not respond as expected.
Fit the Magnet Booster to the intended compatible tool, present the actual fastener & check whether the resulting magnetic retention is useful for the working position. This is more reliable than judging performance from the appearance of the screw.
Use Magnetic Retention for Positioning, Not Alignment
A screw staying on the bit doesn't mean it is entering the material correctly.
Present the fastener squarely to the fixing point & establish proper engagement before applying driving force. Magnetic assistance can help with handling, but alignment remains the operator's responsibility.
Inspect the Driver Tip While You're There
Fastener control begins at the contact point between the tool & screw.
Rounded, chipped or worn driver tips can increase slipping & damage screw recesses. If magnetic assistance is being added because screws are becoming difficult to control, inspect the bit before assuming retention is the only issue.
For practical guidance on recognising equipment problems before they interrupt work, 7 Signs Your Power Tool Needs a Service Before It Fails On Site adds a useful maintenance perspective.
Keep It With the Accessories That Need It
A small tool is only useful on site if someone can find it.
Store the Magnet Booster with the relevant bits, screwdrivers or hex keys rather than loose among general hardware. Portable Organisers can help separate small driver accessories so they remain accessible when crews move between workshop & site.
Don't Confuse Magnetic Holding With Fastener Security
Magnetism helps before & during positioning; the finished connection depends on the fastener.
Once installed, holding performance comes from the selected screw or fixing, its engagement, substrate, installation method & required specification. The Magnet Booster does not increase the structural capacity of the completed connection.
Clean the Accessory When Metal Debris Builds Up
Magnetic accessories can attract the very debris that busy workshops generate.
Check the booster periodically for swarf, filings & other ferrous particles that could interfere with clean handling or transfer debris onto the work area. Keeping small driver accessories clean also makes inspection easier.
Keep Sensitive Items in Mind
A useful magnetic field still deserves sensible handling around equipment that may be magnetically sensitive.
Store & use the Magnet Booster appropriately around electronic equipment, magnetic media, precision devices or other items where a magnet could be undesirable. The accessory should remain with suitable trade tools rather than being carried loose with sensitive equipment.
