Heavy-Duty Timber Fixings for Construction & Trade Applications
Otter | Coach Screws & Bolts provide reliable fastening options for builders, carpenters, contractors & maintenance teams working with timber structures, repairs & heavy-duty fixing applications.
When a connection requires more than a standard wood screw, coach screws & bolts provide a stronger fastening approach through deeper engagement, larger fixing surfaces & mechanical connection options.
Selecting the correct fixing depends on the complete job. Timber type, material thickness, connection design, installation method & environmental conditions all influence the right choice.
The Otter range supports:
► Timber construction projects
► Structural woodworking
► Outdoor structures
► Heavy timber connections
► Workshop fabrication
► Maintenance repairs
► General trade applications

What Are Otter | Coach Screws & Bolts?
Coach screws & coach bolts are heavy-duty fasteners designed for timber connections where dependable holding strength is required.
Although they are often grouped together, they solve different fixing problems.
Coach screws are threaded fasteners installed directly into timber. They are commonly selected when access is available from one side & a direct timber connection is preferred.
Coach bolts pass through the joined materials & are secured with nuts & washers. They are commonly used where a through-connection provides additional control, strength or future serviceability.
The correct option depends on:
► Material thickness
► Timber type
► Connection design
► Installation access
► Required strength
► Future maintenance requirements
For bolt-through installations requiring supporting hardware, browse Nuts & Washers.
Why Choose Otter | Coach Screws & Bolts?
Trade professionals choose heavy-duty timber fixings because the connection matters long after installation is complete.
A correctly selected coach screw or bolt can help create a secure connection that performs under everyday working conditions.
Important considerations include:
► Strong timber engagement
► Reliable mechanical fixing
► Suitable options for thicker materials
► Practical installation methods
► Compatibility with common trade practices
► Suitable choices across construction & repair applications
The fastener is only one part of the connection. Preparation, installation technique & supporting components all contribute to the final result.

Product Selection Guide
Consider The Timber
Timber is not all the same.
Harder timbers, treated timbers & thicker sections may require different preparation compared with softer materials.
Before installation consider:
► Timber species
► Material thickness
► Moisture exposure
► Required holding strength
► Final appearance requirements
Select The Correct Length
The fastener needs enough engagement into the material without creating unnecessary excess.
Too short:
► Reduced connection strength
► Less reliable fixing
Too long:
► Possible protrusion through the material
► Increased installation issues
Measure the complete connection before selecting the fastener size.
Prepare Before Installation
Preparation helps create a cleaner & more reliable fixing.
Recommended practices include:
► Use suitable pilot holes where required
► Align materials before fastening
► Ensure surfaces are correctly positioned
► Avoid forcing fasteners into unsuitable material
► Use appropriate installation tools

Common Timber Fixing Mistakes
Even quality fasteners can perform poorly when installation decisions are wrong.
Avoid common mistakes such as:
► Choosing length without measuring the complete connection
► Using the wrong fixing type for the application
► Installing into timber without suitable preparation
► Over-tightening & damaging the timber surface
► Ignoring environmental exposure
► Selecting fasteners without considering future maintenance
A strong connection starts before the fastener enters the material.
Expert Tips For Better Fixing Results
Match The Fastener To The Job
The strongest-looking fastener is not always the correct choice. Select based on the connection requirements rather than simply choosing the largest option.
Protect The Timber During Installation
Correct preparation helps maintain the integrity of the timber & creates a cleaner finished result.
Consider Future Access
Structures that may require adjustment or servicing can benefit from connection methods that allow easier removal.
Use Quality Supporting Components
Washers, nuts, tools & preparation equipment all contribute to the final fixing outcome.
For additional installation materials, explore Adhesives & Tapes.
Keep The Right Tools Available
The correct installation equipment improves efficiency, reduces damage & helps achieve consistent results across multiple fixing jobs.
Build Complete Fastening Systems
A dependable timber connection relies on more than the fastener alone.
The fixing style, installation method, preparation & supporting components all work together to determine the final result.
Builders, contractors & maintenance teams often benefit from keeping commonly used fastening products available rather than waiting until a project is delayed.
