method the bolt is tightened to a calculated clamp load,
usually by applying a measured torque load. The joint will
be designed such that the clamp load is never overcome by
shaft. This may include clevis linkages, joints that can
move, and joints that rely on locking mechanism (like lock
washers, thread adhesives, an编 d辑loppct k nuts).

Lesson 19 Screws, fasteners and joints 一、Background information
Theory The clamp load, also called preload, of a cap screw is
created when a torque is applied, and is generally a percentage of the cap screw's proof strength. Cap screws are manufactured to various standards that define, among other things, their strength and clamp load. Torque charts are available that identify the required torque for cap screws based on their property class or grade.
用螺纹联接并起紧固作用的零件称为螺纹紧固件。常用的螺 纹紧固件有螺栓、双头螺柱、螺钉、螺母、垫圈等。

screws or studs that capture and join other parts, and are
secured with the mating of screw threads.
There are two main types of bolted joint designs. In one
are not too thick to drill through holes.

Types of screw fasteners 螺纹紧固件的种类
Parts with threads used for joining and fastening are called screw fasteners. The most widely used components as screw fasteners are bolts, double screw bolts---stud, screws, nuts and washers。
