DIN 434 galvanized Square Taper Washers for U-sections are standard components specifically designed for bolt connections of channel steel (U-shaped steel). They are made of galvanized carbon steel and automatically compensate for the angle deviation of the channel steel flange through 10°/12° inclined surfaces, converting the axial force of the bolt into radial supporting force, effectively dispersing stress, preventing the channel steel from collapsing, and enhancing the shear resistance of the connection. They are widely used in steel structure projects such as construction, machinery, power, and rail transportation.

The stainless steel Hexagon Socket Set Screws with Cone Point are made of 304/316 stainless steel and are installed with high torque through the internal hexagon drive. Their sharp conical ends can actively penetrate the surface of the mating part, forming a strong mechanical lock, providing excellent vibration resistance, anti-loosening and precise positioning capabilities. After installation, the head can fully sink into the workpiece, meeting the requirements of compact space, and are widely used for positioning of transmission shafts, fine adjustment of precision instruments and axial locking of automation equipment.

Stainless Steel/Copper Weld Studs (convex welding screws/welding screws), with circular convex points or V-shaped sharp corners at the bottom, can be directly welded to the surface of metal plates with resistance welding equipment. After welding, a permanent threaded connection point is formed without the need for tapping, riveting, or backside operation. 304 stainless steel is rust resistant and corrosion-resistant, and copper material has excellent conductivity.

Jinghong Manufacturer specializes in producing Stainless Steel Helicoil Insertions, which are spiral shaped and can be fitted onto the external threads of bolts or screws to effectively prevent thread collision, rust, and damage during transportation, assembly, and storage. Widely used in automotive parts and other occasions.

Jinghong Factory specializes in producing Countersunk Solid Copper Nails, made of brass or purple copper material, with a 90 ° countersunk head and a solid structure that is flat on the surface after riveting. It has high strength and is permanently fixed with one riveting. Suitable for luggage, clothing accessories, outer packaging boxes, etc. Regular sizes have sufficient inventory and also support non-standard customization.

Jinghong Factory specializes in Bakelite Thumb Screw Nut are supplied, and the handle is made of bakelite. The plum blossom shaped grip is comfortable and can be quickly locked or loosened by hand. Both screws and nuts have metal threads (usually carbon steel or stainless steel).
