China Slotted Screw Manufacturers, Suppliers, Factory

GB/T 73 slotted flat-ended locking screws adopt a headless full-thread design. The top one-way slot can be driven by a regular screwdriver. The end is flat. After tightening, only a shallow indentation will be left on the contact surface, and it will not penetrate the workpiece surface. They are suitable for frequent adjustment or scenarios requiring surface integrity. After tightening, the screws fully sink into the screw holes and do not protrude from the workpiece surface, thus not affecting the movement of adjacent components. The carbon steel blackening/galvanizing provides an economical rust prevention solution, while the stainless steel model meets the requirements of humid or food-grade environments. The product is widely applicable to scenarios such as light-load positioning and axial limitation in instruments and meters, small machinery, electronic appliances, and tooling and fixtures.

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.

Slotted Set Screws with Flat Point are made of Gr4.8 carbon steel and are specially processed with blackening anti-rust treatment.
