China Washer Hardware Manufacturers, Suppliers, Factory

Stainless steel internal and external serrated washers (M2-M20) are made of 304 stainless steel. The double-sided serrated structure on the inner and outer edges can simultaneously engage with the bolt and the surface of the workpiece, providing multiple anti-loosening guarantees. They have excellent corrosion resistance and anti-vibration properties, and are suitable for long-term locking requirements in high-load, high-vibration and harsh environments in the automotive, rail transit, power, petrochemical and other fields.

Jinghong Supplier specializes in providing precision aluminum spacer, manufactured from high-strength aluminum alloys. Featuring lightweight, corrosion-resistant, and excellent thermal conductivity properties, these bushes are suitable for mechanical transmission support, bearing housing positioning, shaft-hole fitting, and pipeline diameter transition connections. A variety of types are available, with surface treatment options supported.

The nylon washers are injection-molded from PA66, featuring excellent insulation properties and chemical corrosion resistance. Jinghong Fasteners offers both black and white options, with a variety of specifications for you to choose, and they can be applied in multiple scenarios.

The Large Plain Washers produced by Jinghong Fasteners are made of high-quality low-carbon steel as the base material. After being precisely stamped and formed, they undergo white zinc electroplating treatment on the surface. This series of washers has a larger outer diameter and thickness compared to standard flat washers, which can effectively increase the contact area and distribute the pressure on the surface of the connecting parts, preventing loosening and surface damage. The specification range covers M3 to M36 and is suitable for various industrial fields where there are high requirements for surface protection and pressure dispersion in bolt and nut connection scenarios.

Stainless Steel C Ring is designed for precise axial positioning in the holes/grooves of bearing seats, valve bodies, and other components. With the excellent rust and corrosion resistance of stainless steel material, it is particularly suitable for food machinery, medical equipment, marine engineering, and work fields with strict requirements for cleanliness and corrosion resistance, providing long-term and reliable positioning guarantee.

DIN 7980 Spring Lock Washers with Square Ends specifically stipulates the technical requirements for spring washers used for Cheese Head Screws. These washers are single-ring helical type spring washers with a square ends, providing preload force through elastic tension to prevent the threaded connection from loosening due to vibration. They are widely used in mechanical manufacturing, electronic and automation equipment, automotive industries, etc.
