► Securefix | Imperial Threaded Bosses

Securefix Weld-On Threaded Bosses Australia for Strong Mounting Points

Securefix imperial threaded bosses are used across Australian fabrication shops & industrial builds where standard threads won’t hold. When material is too thin or load is too high, direct tapping fails fast, threads strip, fasteners loosen & assemblies start moving.

Designed as weld-on threaded bosses, these components create strong, reusable internal threads in steel structures, brackets & custom builds. Once welded in place, they provide consistent thread engagement that holds under vibration, load & repeated use.

For secure connections, trades pair these with Structural Fasteners & Bolts, Hex Bolts & Flat Washer to lock everything down properly. In fabrication environments, teams rely on Welding Machines (Mig, Tig, Arc), Testing & Measurement Tools, Workbenches & Air Compressors to install bosses accurately across UNC & UNF thread applications.

Weak threads fail. Welded bosses don’t.

What’s in This Collection:

► Imperial weld-on threaded bosses
‣ Designed for welding into steel to create permanent threaded mounting points

► UNC threaded bosses
‣ Coarse thread options suited for general fabrication & structural applications

► UNF threaded bosses
‣ Fine thread options for tighter engagement & precision fastening

► Standard imperial size bosses (1/4", 5/16", 3/8", 1/2")
‣ Common sizes for compatibility with imperial fasteners & workshop builds

► Mild steel threaded bosses
‣ Strong, weldable material for fabrication & mechanical assembly

► Zinc plated threaded bosses
‣ Added surface protection for light corrosion environments

Selecting the correct thread type, size & wall thickness ensures connections hold under load without stripping or movement.

Trade Applications for Imperial Threaded Bosses

Strong threads are critical in fabrication, especially where load & vibration are involved.

► Fabrication & metalwork
‣ Create durable threaded mounting points in steel frames, brackets & custom builds

► Mechanical assembly
‣ Provide stronger threads where direct tapping would fail or strip

► Machinery builds & repairs
‣ Replace worn or damaged threads with welded reinforcement

► Automotive & transport fabrication
‣ Add mounting points for guards, brackets & structural components

► Industrial maintenance
‣ Restore thread integrity in equipment to extend service life

► Workshop & engineering environments
‣ Support builds where secure, repeatable fastening is required

Where threads are likely to fail, threaded bosses provide a permanent fix.
