SKU CH-44Z1-21MPH

Pack of 15 steel tab weld nuts, 1/4"-20 threads, 5/16" length, MPN 931384

  • TypeNuts
  • Secure threaded weld points with 1/4"-20 steel tab nuts
  • Fifteen-piece pack covers multiple fabrication or repair jobs
  • 5/16" length suits thin-sheet and bracket applications
  • Steel construction resists vibration in automotive and structural assemblies
  • Ready-to-weld tabs eliminate drilling and tapping steps

Project Fastener Kit

This pack contains fifteen tab weld nuts with a 1/4"-20 thread size made from steel. Each nut measures 5/16 inch in length and is designed for permanent attachment by welding. The hardware suits automotive repair, fabrication and general assembly tasks where a strong, load-bearing threaded anchor is required.

Replaces Loose Hardware

The nuts replace individual self-tapping screws or bolt-and-nut combinations that can loosen under vibration. A welded tab nut provides a fixed thread that will not back out, making the upgrade worthwhile on chassis brackets, mounting plates or any joint subject to repeated shock. The fifteen-piece quantity covers multiple mounting points in a single job.

Verify Thread And Material

Confirm the mating bolt uses a 1/4"-20 thread pitch before ordering. Ensure the base material is weldable steel and that your welding equipment can access the tab area. Check that a 5/16 inch overall length fits the stack-up thickness of the parts being joined.

Questions about this item

What thread size and length does the 1/4"-20 tab weld nut have?

The nut uses a 1/4"-20 thread and is 5/16" long, matching the 15-pack specification.

How do I install these tab weld nuts correctly?

Position the nut, tack-weld the tabs to the workpiece, then complete the welds; the common error is skipping the tack step, which lets the nut shift before full fusion.

When should I replace a tab weld nut after installation?

Replace any nut that shows cracked welds, stripped 1/4"-20 threads, or corrosion that prevents a bolt from seating fully.
