Fasteners / Nuts

Nuts

The fastening side of every threaded assembly. Hex finish nuts for general bolt-and-nut work, locknuts (Kep, Nylock, reverse) for vibration-prone connections, smaller machine screw nuts, and tee nuts for wood applications where the threads need to live behind the workface.

HXFINUTHex Finish Nuts

Hex Finish Nut. The standard companion to hex cap bolts, carriage bolts, and lag screws. Slightly thinner profile than a heavy hex nut. Sizes 1/4″–20 through 3/4″–10 in zinc, plain, and hot-dipped galvanized.
