At South Coast Fasteners, Inc., we supply metric weld fasteners built to stay put. Whether you're manufacturing structural frames, automotive components, or sheet metal assemblies, our selection of weld nuts and consumables offers strength, consistency, and compatibility with automated and manual welding processes. From weld nuts to tabbed spot weld options, our hardware is made to deliver uniform weld penetration and thread integrity where it matters the most.

Standards and Weld Compatibility

All metric weld fasteners provided by South Coast Fasteners are produced to meet DIN and ISO standards for dimensional accuracy, material composition, and weld performance. Manufactured from low-carbon or weldable steel, these fasteners are optimized for resistance welding, MIG, and spot-weld operations in a slew of fabrication environments.

 

Available Metric Weld Fasteners

Metric Hex Weld Nuts

Designed for resistance welding to sheet metal, these internally threaded nuts provide permanent threads in high-loaded applications. Hex weld nuts are ideal for automotive, HVAC, enclosure, and chassis manufacturing.

Available with two pilot styles to suit application needs:

  • Short Pilot Hex Weld Nuts: Minimal protrusion into the base material, perfect for thinner sheet stock where reduced weld depth is required.

  • Long Pilot Hex Weld Nuts: Extended pilot provides better alignment and increased thread engagement, ideal for deeper plates or layered weldments.

Both versions offer excellent current conduction and consistent weld projection profiles for reliable fastening in automated or manual welding setups.

Metric Spot Weld Nuts

Spot weld nuts feature precision projections or tabs designed for quick fusion to metal surfaces. They create clean, reusable threads without post-weld machining. Available configurations include:

  • Single Tab: Easy alignment with one positioning tab. Great for corners and tight access installations.

  • Double Tab: Stabilizes nut orientation during weld and prevents rotation. Common in bracket and frame applications.

  • Dual Rib Projection: Raised ribs act as projections to concentrate heat and ensure secure weld fusion with minimal distortion.

  • Four Projections: Offers balanced current flow and even fusion on all sides, ideal for high-strength mounting points or structural attachment.

  • Single Tab with Single Projection: Combines easy placement with a focused, single projection weld point for localized strength without excessive heat spread.

Spot weld nuts are stocked in multiple thread sizes and body configurations to suit various base materials and weld accessibility conditions.
