Jinghong Factory specializes in producing stainless steel Hexagonal Cylinder Head Shoulder Screw, which is formed by cold heading 304 stainless steel. The head is an inner hexagonal cylindrical head, and the rod has a precision step (smooth rod) with threads located at the end. This type of screw is used on parts that require rotation or positioning. The step part is fitted with a gap between the fitting hole, and after tightening, the screw can rotate and also serve as a positioning tool. The length and diameter of the steps can be customized according to the drawings, and regular sizes are readily available in stock.

The black stainless steel cross-point self-tapping screw is a metal fastener that combines both anti-corrosion properties and aesthetic texture. It is made from 304 or 316 stainless steel as the base material. After surface blackening or oxidation treatment, it presents a matte black color. The head adopts the standard cross-point design, and the thread is a self-tapping type. It can directly drill out the thread on thin metal sheets, plastics, or woods without the need for pre-drilling. This product is suitable for connection scenarios with requirements for both smooth appearance and anti-corrosion performance, such as building decoration, fixing the shells of electronic devices, and outdoor display stands.

The black PA66 cross-head machine screw (GB/T 818 nylon machine screw) is a non-metallic fastener made by injection molding of polyamide 66 (Nylon 66) engineering plastic.

It complies with the GB/T 818 standard. This screw is specifically designed for connection scenarios that require electrical insulation, no magnetism, corrosion resistance, and no damage to the substrate. It is usually used in conjunction with nylon locking nuts or plastic/metal parts with internal threads. The common specifications are M2 to M8.
