CORWIN 1/4-20 Extended Rivet Nut Gun Mandrels and Nosepiece Set, Specifically Designed for Installing Pre-bulbed Rivet Nuts and Similar Threaded Inserts. Multi-Grip

Purpose: Specifically designed for the installation of pre-bulbed rivet nuts and other extended rivet nuts Multi-grip

Compatibility: Compatible with manual rivet nut guns, not for standalone use.

How to Confirm Compatibility: If your rivet nut gun's standard mandrel accessories are stored in a colored plastic storage box, the thread for installing the mandrel is M8*1.25mm, and the connecting seat matches the internal hexagon spring lock sleeve, then it is suitable.

What You Will Receive: One 1/4-20 extended mandrel and one 1/4-20 nosepiece.

Notes: a. The extended design facilitates the installation of extended rivet nuts but requires more rotations when installing standard rivet nuts. b. Like standard mandrels, pay attention to the operation stroke to avoid overloading, meaning stop applying force when the rivet nut is deformed into place. c. When installing the mandrel, ensure all threads are screwed in before adjusting the spring sleeve to lock it in place for a secure connection.
