Corbin Thumbscrews

The seat-tab thumbscrew makes installing and removing your saddle a snap.

NEW single piece design cut from stainless steel. Featuring a machined satin finish on top with a fine tooth knurling on the side for grip. One piece design means it won't ever leave the threaded part behind! All Corbin thumbscrews will change over to this model as current inventory of chrome models is depleted. See description below for current status of all models.

Billet aluminum thumbscrew has knurled sides to make gripping it without tools easy. Black oxide theaded insert. Available in a variety of SAE and Metric sizes as inventory lasts. Works great for just about anything you want to secure tool free!
