This rivet nut tool features a SPIN-PULL-SPIN setting sequence. In one touch the fastener quickly spins on, pulls the fastener, and with the release button, spins out of the fastener. Setting cycle is about 2 seconds. This means less thread deformation. The BP-60 Rivet Nut tool has a fully adjustable stroke for accurate insert placements, which requires less operator skill. Stroke adjustment is quick and easy, and is done from exterior of the riv nut tool. Mandrels are included with tool. Comes complete with sizes 8-32 through 1/2-13 or M4 through M12. "More Power" means this tool uses its huge 6800 lbs. of pulling force to set up to 1/2 (M12) steel rivet nuts with ease. Recommended operating air pressure is 80-100psi. Weight 6 lbs.
