This 304 stainless steel mother-and-child rivet (also known as ledger pin, double-lock screw, or recipe book pin) consists of a male and female component, both made from stainless steel and manufactured as a single unit. The head features a flat design with a cross or straight slot, allowing for easy tightening with a screwdriver. Its interlocking structure securely clamps multiple layers of material, offering a smooth, neat appearance that is rust-resistant and durable. It serves as a versatile fastener ideal for binding, decoration, and securing applications.

Jinghong Factory specializes in producing Stainless Steel Flat Head Watch Screws, which are formed by cold heading stainless steel and have a countersunk conical surface. After installation, they are flush with the surface and have clear cross grooves. They can be easily operated with a screwdriver. Suitable for micro assembly occasions with small spaces such as watch cases and precision instruments. Regular size stock is abundant, supporting customized non-standard lengths and head shapes.

Jinghong Factory specializes in producing Hex Socket Cone Point Grub Screw, which is made of stainless steel with a hexagonal head and a pointed tail. The product is used to fix the position and relies on the tip to firmly position it. Widely applicable in situations that require precise positioning. The specifications range from M3 to M16, with sufficient stock of regular sizes and support for non-standard customization.

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.
