Washer Face Thumb Screws

Lyn-Tron's Washer Thumb Screws are designed to be installed by hand rather than by hand tools or power tools. The high-quality knurl provides a non-slip surface to grip onto. In addition, the washer face provides a decorative appearance, but also adds clearance between the head and mating part making these screws easy to unscrew compared to a plain thumb screw.

Washer Face Thumb Screws are one-piece screws machined out of a solid bar. The one piece design means you will not have to search for a lost washer during installation or maintenance as it is integrated and a part of the head itself. The washer also allows the knurled gripping surface to be above the mating piece, making it easier to grip when uninstalling.

A Thumb Screw with a Washer Face is often used instead of fasteners as they can be installed or taken out by hand. This can avoid causing damage to a mating part by preventing the screw from being overtightened with a power or hand-tools. The Washer Face screws are a good solution for components and applications that need frequent cleaning, maintenance or monitoring.
