To set the correct, precise preload in bolted joints, you must choose the appropriate bolt tightening method.

2
00:00:07,000 --> 00:00:13,583
Insufficient preload caused by an inaccurate tightening method is a frequent cause of bolted joint failure.

00:00:13,583 --> 00:00:18,042
Four main methods are used to control the preload of a threaded fastener:

4
00:00:18,042 --> 00:00:19,417
1. Torque control

5
00:00:19,417 --> 00:00:23,000
2. Angle control (also known as turn-of-the-nut)

6
00:00:23,000 --> 00:00:26,292
3. Bolt stretch or elongation measurement

7
00:00:26,292 --> 00:00:27,667
4. Tensioning
