⚡ At a Glance
- • Weldability: Flat solder joints and carbon steel make for consistent, strong welds
- • Best for: Workshop fabricators, furniture makers and maintenance engineers needing secure welded threaded anchors
- • Not ideal for: Applications that require stainless steel or enhanced corrosion resistance
Square carbon steel weld nuts with M12-1.5 UNC threads supplied in packs of 10. Precise thread sizing and flat solder joints support reliable welded joins for furniture and light industrial fittings.
Secure threaded joins – thanks to M12-1.5 UNC thread accuracy
M12-1.5 UNC threads are cut to match standard M12 fasteners, with a square base to hold orientation during welding. Grade 4.8 carbon steel provides a balance of tensile strength suitable for typical furniture and caster fittings.
Accurate threads mean bolts screw in smoothly and remain tight after welding, reducing time spent on rework. Suitable for assembling shelving, frames and caster mounts where a reliable threaded anchor is required.
Consistent welds with flat solder joints – with carbon steel construction
Flat solder joint faces minimise gaps at the weld interface, allowing even heat distribution and stronger fusion. Carbon steel chemistry promotes good weldability when surfaces are cleaned and prepared.
Flat joints help produce repeatable, neat welds and reduce the need for excessive filler. That makes it easier to achieve tidy, structurally sound connections on repeated production or repair tasks.
Quicker alignment and assembly – with a square body for stable positioning
A square nut body resists rotation during tack-welding, helping keep the thread vertical while the first welds are set. The reported width and height give a predictable footprint for locating on tubular or flat surfaces.
Stable positioning cuts fiddly adjustments and speeds up tack-welding, so assembly flows faster. Practical when mounting multiple nuts to a frame or restoring several connection points in one session.
