Radial Engineering ThumbSet Thumbscrews for 500 Series Racks & Modules

Thumbscrews for 500 Series racks & modules, 12 screws & washers.

The ThumbSet screws feature a perfectly sized thumbscrew head for easy mounting without the need of a screwdriver. However, if ever the ThumbSet is over-tightened, a clever slotted head allows a screwdriver to be used to loosen.
