Cap Nut

Providing a smooth finish on applications in a variety of industries, a cap nut may also be labeled an acorn nut. The cap covers a screw head to create a catch-free surface and presents the convenience of a hex-shaped nut for tightening and loosening. Melfast offers cap nuts in a range of sizes, from 1/4-20 through to 3/4-10, and materials, including alloy, stainless steel and titanium. Ask about platings available on certain materials.

At Melfast, we produce state of the art slotted hex nuts in steel, brass and stainless steel in passivate and zinc (Clear) platings.
