China Aluminum Formwork Accessories manufacturers When choosing the material of Squared washer, we need to choose according to the requirements of flat washer surface hardness, specific occasions and our own budget. The effect of flat pad 1. Increase the contact area between screws and machines. 2, eliminate the spring pad when removing screws on the machine surface damage. The washer must, when used, be next to the surface of the squared machine, with the spring washer between the flat washer and the nut. Flat pad is to increase the force surface of the screw. Spring pad in order to prevent screw loose, the force plays a certain amount of buffer protection. Although flat MATS can make sacrifice MATS. 3. But more often it is used as a supplementary pad or flat pad. Advantages: (1) By increasing the contact area, parts can be protected from damage; 鈶?By increasing the contact area, reduce the pressure between the nut and the equipment, so as to play a protective role In daily life, a plastic screw squared washer may have the following functions: 1. Increase the contact area between screws and machinery 2, eliminate the damage to the mechanical appearance of the spring pad when removing the screw. When used, it must be: the spring pad is a flat pad, the flat pad is next to the mechanical surface, the spring pad is between the flat pad and the nut. Flat pad is to increase the force surface of the screw. In order to avoid screw loosening, spring pad plays a certain amount of buffer maintenance effect. Of course flat mat can do sacrifice mat. But more time is used as supplementary pad or flat cushion. And the spring pad acts as a locking piece. If the workpiece hole and screw diameter value (S) is too large, do not use flat pad or directly use spring pad, not only will damage the workpiece, the first is the screw also not only fixed or cohesion effect. In particular, components for high-intensity tasks. Thus in the use of spring pad, when (S) in the limit of the promise can not use flat pad.China Aluminum Formwork Accessories manufacturers website:http://www.hbbestbuyhardware.com/aluminum-formwork-accessies/
