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.
