CORWIN 1/4-20 Extended Rivet Nut Gun Mandrels and Nosepiece Set, Specifically Designed for Installing Pre-bulbed Rivet Nuts and Similar Threaded Inserts.
Purpose: Specifically designed for the installation of pre-bulbed rivet nuts and other extended rivet nuts.
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 M5 extended mandrel and one M5 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.
