Quarter-Turn Thumb Screws

Connect and disconnect jigs, lids, and plates without removing these thumb screws. The rectangular head slides into a matching slot on your workpiece. Then, twist the head one quarter turn to latch the workpiece into place.

Length is measured from under the head.

Black-Oxide Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Vibration-Resistant Captive Panel Screws

An expanding rubber bushing damps vibration while holding panels together. To install, push the threaded end through a hole in the outer panel, slide on the bushing, and tighten the nut. Next, insert the assembly through the inner panel hole and flip the handle to fasten. They become a part of the panel when installed, so they won't fall out and get lost.
