Torque Wrenches The three most commonly used torque wrenches are the flexible beam, rigid frame, and the ratchet types. [Figure 7-33] When using the flexible beam and the rigid frame torque wrenches, the torque value is read visually ... bolt in a clockwise direction with a smooth, steady motion. (A fast or jerky motion results in an improperly torqued unit.) When the applied torque reaches the torque value indicated on the handle setting, the handle automatically releases or “breaks…

stud to the bottom of the spring hole. A quarter of a turn of the stud (clockwise) locks the fastener. The fastener may be unlocked only by turning the stud counterclockwise. A Dzus key or a specially ground screwdriver locks ... unlocks the fastener. Camloc Fasteners Camloc fasteners are made in a variety of styles and designs. Included among the most commonly used are the 2600, 2700, 40S51, and 4002 series in the regular line, and the stressed panel fastener…
- Chapter 7: Aircraft Materials, Hardware, & Processes › Aircraft Metals › Torque Tables
Torque Tables Use the standard torque table as a guide in tightening nuts, studs, bolts, and screws whenever specific torque values are not called out in maintenance procedures. The following rules apply for correct use of the torque table: [Figure ... first if possible. When space considerations make it necessary to tighten by rotating the bolt head, approach the high side of the indicated torque range. Do not exceed the maximum allowable torque value. 4. Maximum torque ranges should be used…
