The idea behind this fastener started with a common problem seen in pit stalls at race tracks across the country.

Madco Motorsports recognized areas where a standard nut was nearly impossible to start in a tight location or would slip out of the socket as soon as the tool is angled downward.

The Madco Ratchet Fit Fastener is a uniquely designed fastener that provides ultimate control and minimal loss while starting the thread.

This fastener features a standard square recess that snaps directly to your extension as would a socket while the other end is threaded to accept the male stud.

Our performance racing line is machined from light weight 7075 aircraft aluminum alloy in our state of the art CNC machine shop then anodized to increase durability and laser engraved for visual appeal.

The Madco Ratchet Fit Fastener is ideal for areas where hardware is frequently serviced and replaced in difficult to reach locations.
