1  Introduction 

Heavy Head Hand Tools (HHHT) 525692, 59239-4, 59239-8, and 59287-2 are the tool and die set shown in 
Figure 1. These tools are designed to crimp the product listed in Table 1 onto the wire also listed. 

For other tools accompanied by this instruction sheet, follow the instructions for the tool used to crimp the same 
wire size. 

NOTE 

Dimensions in this instruction sheet are in millimeters with [inches in brackets]. Figures are for reference only and are not 
drawn to scale. 

Read these instructions thoroughly before crimping connectors.
