Carbon steel/alloy steel automotive Car Wheel Bolts, classified according to strength grades 8.8/10.9/12.9, provide 60 ° conical, spherical, and planar contact types. The keyway and wheel hub hole are fitted with interference fit for precise positioning. Suitable for passenger cars, light trucks, and heavy trucks, high-strength material selection, anti loosening and rust prevention, stable and reliable road testing.

The DIN557 stainless steel square nuts are made of A2 or A4 stainless steel and possess excellent corrosion resistance. Their square structure is specifically designed for anti-turning and slot rail installation, enabling them to effectively fit into the T-shaped slots of industrial aluminum profiles or the edges of structures, preventing slippage during tightening. They are particularly suitable for frame assembly, welding structures, and single-side operation scenarios. The specifications range from M5 to M16. They are an efficient fastening solution for mechanical equipment, racks, and general industrial connections.

304 stainless steel hex head screw with column, featuring a hexagonal slot and a central anti-tamper post. It can only be driven with a specialized hollow hex bit; standard Allen wrenches, flathead, or Phillips screwdrivers cannot fit. Designed for use in equipment requiring anti-tampering and anti-disassembly protection.

Flat Thin Head Screw has a flat head that is almost parallel to the workpiece after tightening. It has been treated with blackening, matte black, and does not reflect light. It is suitable for installation inside equipment or on external components. Cross groove drive for quick locking.

Slotted Set Screws with Flat Point are made of Gr4.8 carbon steel and are specially processed with blackening anti-rust treatment. They have stable strength, good wear resistance and oxidation resistance. The one-slot opening structure makes them easy to install and remove. The headless conical end design allows them to be inserted into the workpiece, saving installation space. They achieve precise positioning and anti-loosening locking by means of compression. The specifications are complete, the teeth are precise, and they have strong versatility. They are suitable for various scenarios of positioning and tightening of mechanical parts, shaft sleeves, handwheels, and workholding fixtures.

The stainless steel chemical anchor bolts are made of high-quality 304 stainless steel, featuring anti-corrosion and anti-oxidation properties. They are based on the principle of chemical bonding and curing, without generating expansion stress. They possess high tensile and shear strength, stable anchoring performance, and a long service life. They come in various specifications and are easy to install. They are widely used for post-installation anchoring and fixation of concrete, stone, and other substrates, and are applicable to curtain wall engineering, equipment fixation, structural reinforcement, and marine corrosive environments.
