Thread-locking Male-Female Threaded Hex Standoffs

Secure components on vibrating machinery. A nylon patch adds friction so the standoff won't loosen in environments that shake, rattle, or rotate. To securely tighten standoffs, grip the flat sides of the hex body with a wrench.

Corrosion-Resistant 18-8 Stainless Steel—The choice for wet and outdoor environments, these standoffs resist rusting. They're strong enough for most jobs, but won't withstand stress as well as steel.
