Product Details
Stainless steel screw wire, also known as stainless steel cold pier wire, is mainly used for various fasteners, such as mechanical components and electronic application components. According to different materials, corresponding anti-corrosion and mechanical properties can be obtained. In order to obtain a better formability during cold forging, high quality shall be selected. The appropriate material of wire is particularly important.
Washers are divided into: flat washer - C grade, large washer - A and C grade, extra large washer - C grade, small washer - A grade, flat washer - A grade, flat washer - chamfer type - A grade, high-strength washer for steel structure, spherical washer, conical washer, square bevel washer for I-beam, square bevel washer for channel steel, standard spring washer, light spring washer, heavy spring washer, inner tooth lock washer, inner tooth lock washer, outer tooth lock washer, outer tooth lock washer Single ear stop washer, double ear stop washer, outer tongue stop washer, and stop washer for round nuts.
The lifting ring screws should be made of 20 or 25 steel (GB699). The lifting ring screws must be integrally forged, and the forging should be normalized and free of oxide skin. The grain size of the finished product should not be lower than level 5 (YB27-77), and the forging should not have overburning or crack defects.
DIN6796 Belleville Spring Washers (HDS series) are anti loose washers designed for bolt and screw connections. It is designed and manufactured according to DIN 6796 and is used for the connection of medium or high strength bolts and screws. The high support load and elastic recovery make the HDS series very effective. The bolt tension can withstand relaxation caused by wear, creep, relaxation, thermal expansion, contraction of vulnerable parts, or compression of sealing components. The HDS series has increased the elastic effect of screws several times, and it can effectively replace ordinary spring washers, but is not suitable for use as a combination of lock washers and flat washers.
