PULLING HEADS 

Pulling heads are not furnished and must be ordered separately. Make certain the pulling head is kept clean, especially around the 
riveting end, as adhesives, chips, sealants, etc., will clog up the serrations of the jaws and may cause slippage of the stem. Please 
refer to the pulling head charts below for the proper selection. 

TOOL CAPACITY CHART 

The numbers shown in the rivet columns below are the maximum grip length that can be installed with this tool. Dashes indicate those
