This product allows you to make tool-less adjustments to your Bridgelock mounted sight. The screw is a nylon tipped, stainless steel screw with a plastic knob that replaces the factory provided mounting set screw. No need to grab your Allen Keys next time you need to case your bow. 

Disclaimer: In some cases the threads on your bow will need to be cleaned out (see last photo). The knob will make contact with an arrow if using the Mathews low profile FIXED quiver. The Mathews low profile detachable quiver has clearance and doesn’t affect functionality.
