Fastener hardware for sheet-metal joins, designed to make welded connections reliable and repeatable. METALLIXITY Spot Weld Nuts combine M6 threading and a double-tab form for workshops, marine fittings and furniture repair. Are these robust enough for repeated welding and heavy use on workshop projects?
⚡ At a Glance
- • Holding Strength: M6 x 1mm thread with a centred hole and double-tab contact for secure welded joints
- • Best for: Machinery builders, metal-shelf installers and DIYers doing furniture or appliance repairs
- • Not ideal for: Applications that require removable, non-welded fastenings or specialised stainless-steel fittings
M6 threaded nuts use a centred hole and double-tab layout to accept spot welding. Cold-forged carbon steel construction prioritises durability and resistance to corrosion and wear.
Secure, low-profile joins – Thanks to M6 thread and centred hole
Thread size is M6 x 1mm with a centred hole and a solder joint height of 1mm, allowing bolts to pass through while keeping the welded head low. The overall footprint measures 23mm x 14mm x 8mm for predictable fit in slot holes.
Reliable nut threads resist pull-through on thin sheets and keep assemblies flush, useful when fitting metal shelving, cabinets or appliance brackets.
Durable corrosion resistance – With cold-forged carbon steel construction
Manufactured by cold forging from carbon steel and described as corrosion-resistant, rust-resistant, heat-resistant and wear-resistant. The material choice and forming method increase hardness and fatigue life compared with stamped alternatives.
Long service life suits workshop or marine environments where repeated use and exposure would quickly wear lesser fasteners.
Faster production welds – With double-tab spot-weld design
Double tabs provide larger contact area for spot welding and help align the nut in slot openings; the centred hole simplifies bolt insertion after welding. Tabs reduce the chance of nut movement during the welding cycle.
Assembly speed improves for production runs and repair jobs, making installation quicker and more consistent on repetitive tasks.
✨ The 4 Key Reasons for METALLIXITY Spot Weld Nuts
