Setscrews are available on this page in many popular sizes. Standard stainless steel setscrews, are available in all sizes except 6-32. We offer 6-32- and 8-32-threaded alloy steel setscrews with a non-marring nylon tip. We also offer double-ended setscrews, which are designed to be easily removed from posts or mounts. With a hex socket on both ends, extraction is straightforward and simple, eliminating the need for pliers and the frustration of stuck screws.

1/4"-20 and M6 x 1.0 Thumbscrews for Post Holders

 

Spring-Loaded Hex Locking Thumbscrews (TS25H and TS6H/M): These anodized aluminum thumbscrews have spring-loaded, completely retractable Delrin™ tips that provide sufficient force on a post to hold it in place as final positional adjustments are being made. They can then be locked into place using a 3/16" or 5 mm balldriver to prevent any further movement of the post. The hex size is also engraved on the face of the thumbscrew, thereby enabling easy identification in the lab.

The TS25H is 1/4"-20 threaded for compatibility with our imperial Ø1/2" Post Holders, while the TS6H/M is M6 threaded for compatibility with our metric post holders. Please note that we do not recommend using an L wrench to tighten the thumbscrew in place, as this may break off the screw head. Recommended max torque: 28 in·lbs.
