Hillman SAE Nylon Insert Lock Nuts, 7/16 in-14, Steel, Zinc, 50/CT

Tight, steady fastening that helps keep your hardware from backing off.

A solid pick for bolts that need a little extra grip.

Product Overview:

When a joint starts to work loose, you feel it fast. This lock nut gives your fastener a steadier hold, with a nylon insert that adds rotational resistance once the bolt seats. It fits a 7/16 in-14 coarse thread setup, so it lines up cleanly when you are putting materials together and want the job to stay put. The steel body with zinc finish brings a practical, no-nonsense look and a bit of extra corrosion resistance. Picture the hardware settling in, snug and quiet, instead of rattling itself free later. That is the kind of calm you want when the work has to hold.

Key Features:

• Nylon insert gives the nut added bite, so your connection stays put when vibration starts acting up.
• 7/16 in-14 coarse thread matches the right bolt setup cleanly, which saves you a bit of fuss.
• Steel construction handles everyday fastening jobs with a sturdy feel you can trust.
• Zinc finish helps the nut stand up better in tough conditions and keeps the surface looking tidy.
• 50 count box gives you a handy supply on the shelf, so you are not hunting for one last nut mid job.
