BOLT TORQUING GUIDELINES
Proper bolt installation is critical to ensure the safe and effi cient operation of the attachment and jaw set.
Carefully follow the steps below to properly install bolts.
1. Always replace bolts and nuts with the same size and class of fastener. Replacement fasteners can be
ordered from the LaBounty Parts Department to ensure the correct part is used. Unless otherwise speci-
fi ed, use class 10.9 metric hex head capscrews, class 10.9 metric fl at head capscrews, and class 12.9 metric
socket head capscrews.
2. Make sure bolts, nuts and bolt holes are free of dirt, oil, grease and other contaminants.
3. If necessary, use the Capscrew Size Guide, below, to determine the size of the bolt being installed.
4. Use the Dry Bolt Torque Chart, below, to fi nd the proper torque. When possible, torque the nut rather than
the bolt head.
