Stainless Steel Trox Flat Head Machine Screw, 304 material, countersunk head, hexagonal drive. The head remains flush with the surface after tightening, ensuring no sharp edges. The hexagonal drive offers better torque transmission than a cross-head, reducing the likelihood of slipping and ensuring efficient torque transfer.

Jinghong Factory specializes in producing Nylon Grub Hex Screw, which is made of high-quality nylon injection molded or machined. The head is an inner hexagon and the tail is flat. Nylon material is non-conductive and non-magnetic, and does not damage the workpiece. After tightening, nylon locks the position by friction, playing a role in preventing loosening. The length can be customized according to demand, and regular sizes are readily available in stock.

The stainless steel square wing nut is a hand-tightening fastener made of 304 or 316 stainless steel. The design with square wings on both sides enables it to be quickly tightened or disassembled without tools, significantly improving the operational efficiency in frequent assembly and disassembly scenarios. The square base effectively prevents the nut from rotating, ensuring a stable connection. The stainless steel material gives it excellent rust and corrosion resistance, allowing it to be used for a long time in humid, outdoor, and chemical environments. This product is widely applicable in manual quick-connecting scenarios for light to medium load fastening in mechanical equipment maintenance doors, pipeline valves, assembled furniture, and outdoor facilities.

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. The surface is treated black. The head is a rounded arc-shaped disc with a standard cross slot (PH type), and the thread is metric coarse machine thread (including full thread and half thread). 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.
