5.5 FACTORS THAT CAN AFFECT HANDLING TORQUE
1. Working conditions
Fastening torque can vary even for bolts of the same diameter.
The transmitted torque can change depending on bolt grade,
length, coefficient determined by bolt quality/work condition,
condition of bolt seating, and distance between fasteners. Torque
transmission can also be affected if the bolt and nut rotate
together even after fastening.
2. Engagement gap among socket, UBX, and fastener
Ensure that fit of the tool anvil to the driving socket and the socket
engagement to the fastener are tightly toleranced. Poor fit of the
tool anvil to the socket and/or poor fit of the socket to the fastener
will result in inaccurate torque delivery to the tightened joint.
3. Trigger
Keep trigger fully squeezed until the tool automatically shuts off.
Early release of the trigger can cause automatic shut-off to fail.
4. Low torque posed by inclusion between UBX and socket
A universal joint, connector, or long socket that increases the
distance from the tool to the fastener can reduce torque
transmission.
