This is our most powerful air/hydraulic threaded insert setting tool. This 

spin-pull tool automatically threads the fastener onto the mandrel. Press 

the trigger just once and the fastener is installed. Reverse the trigger and 

the mandrel spins out of the fastener. The 39221 features a totally 

adjustable stroke length to suit any grip range and a swivel air inlet for 

increased mobility. No complicated tear down is required to adjust the 

stroke or to change thread sizes…both adjustments are done outside the 

tool. The 39221 handles rivet-nut sizes 4-40” through ½-20” and 3.5mm 

through 12mm in aluminum or steel. 6-32” through 3/18-16” mandrels and 

nosepieces are included. Weight: 6 lbs. 

 

Tool also available with metric mandrels and nosepieces, part number
