Steel Thread-Locking Socket Head Screws

Lock parts in place on vibrating machinery. These screws have threads with a bonded nylon patch, saving you the time and mess of adding threadlocker yourself. Made of alloy steel, these are some of our strongest screws. Their deep, six-point socket keeps hex keys from slipping out and damaging the drive. Length is measured from under the head.

• Black-Oxide Alloy Steel— Best for dry environments since moisture will cause these screws to rust. They have a dark, matte appearance.
