Customized 10.9 grade blue and white round head with cushion hexagon socket head bolt with cushion round cup with cushion screw 3/4 5/8

The existing adjusting screw is generally composed of a screw and a nut on the top of the screw. The screw is driven to rotate by means of a screwdriver, and then the screw is driven to rotate. In and out, adjusting other objects connected to it and changing position accordingly.

1. Precautions for the quality of high-strength bolts or screws and flat washers assemblies. The surface of the Phillips hexagon combination screw should be checked for burrs or scratches. There is no oil stains, or rust. To test the material of the combination screw, the strength of the grade used in different high strengths should be consistent with it. Second, the combination bolt and nut should be used together with the same grade as the nut, and the same grade should be used together. Third, when installing and using combined bolts, it should be in reasonable weather conditions and should not be operated in the rain. Fourth, when installing, it is forbidden to use excessive force and excessive force. Lead to sliding teeth, or locking phenomenon.

The four corners of the bolt head of the traditional T-slot connection bolt are all rounded corners, which will make the contact area between the bolt and the T-slot too small and reduce the connection fastness, especially when used for connection. When aluminum or copper profiles are used, due to the low hardness of the material, it is more likely to cause deformation of the T-shaped groove and affect the connection effect. Furthermore, since the traditional T-bolt has no direction indicator, it is difficult for the installer to identify the installation state during installation.

DIN6796 Disc Spring Washers (HDS Series) are lock washers designed for bolted and screwed connections. It is designed and manufactured according to DIN 6796 for the connection of medium or high strength bolts and screws. High bearing loads and elastic recovery make the HDS series very effective, and the bolt tension can withstand slack due to: wear of consumables, creep, relaxation, thermal expansion, contraction, or compression of seals. The HDS series increases the elasticity of the screw several times. It can effectively replace the ordinary spring washer, but it is not suitable for the combination of lock washer and flat washer.
