V. TIGHTENING TORQUE

The power required for tightening a bolt will vary, according to bolt material and size, as well as the material being bolted. Choose the length of tightening time accordingly.

Reference values are provided below.

(They may vary according to tightening conditions.)

Factors Affecting Tightening Torque

The tightening torque is affected by a wide

variety of factors including the followings. After tightening, always check the torque with a torque wrench.

1) Voltage

When the battery pack becomes nearly discharged, the voltage decreases and the tightening torque drops.

Tightening conditions

• The following bolts are used.

Standard bolts: Strength type 4.8

High tensile type 12.9

2) Tightening time

Longer tightening time results in increased tightening torque. Excessive tightening, however, adds no value and reduces the life of the tool.

3) Different bolt diameters

The size of the bolt diameter affects the tightening torque.

Generally, as the bolt diameter increases, tightening torque rises.

4) Tightening conditions

• Tightening torque will vary, even with the same bolt, according to grade, length, and torque coefficient (the fixed coefficient indicated by the manufacturer upon production).
• Tightening torque will vary, even with the same bolting material (e.g. steel), according to the surface finish.
• Torque is greatly reduced when the bolt and nut start turning together.

5) Socket play

Torque is lowered as the six-sided configuration of the socket of the wrong size is used to tighten a bolt.

6) Switch (Variable speed control trigger)

Torque is lowered if the unit is used with the switch not fully depressed.

7) Effect of Connecting Adaptor

The tightening torque will be lowered through the use of a universal joint or a connecting adaptor.

VI. ACCESSORIES

Use only suitable size of bit.
