Lock washer is also known as lock washer, self-locking washer, din25201 lock washer, double stacked self-locking lock washer, double stacked wedge lock washer, etc. The lock washer is composed of two gaskets of uniform specification. The outer side of each gasket is provided with a radial convex surface, and the inner side is a helical tooth surface. The tension between the two gaskets is used to achieve the dual effect of locking and tightening. The basic materials are carbon steel and stainless steel.

serrated washer has internal tooth elastic washer and external tooth elastic washer.There are many sharp elastic warping teeth on the circumference, which stab and press on the bearing surface to prevent the loosening of fasteners. The internal tooth elastic washer is used under the screw head with small head size; External tooth elastic washers are mostly used under bolt heads and nuts.

Nylon washer has excellent insulation performance, non-magnetic, heat insulation and light weight. The plastic washer of some materials also has high temperature resistance, high strength and corrosion resistance. Some products have anti falling function and are widely used in semiconductor, automobile, aerospace industry, interior decoration and other fields. More than 10 kinds of materials are used, including PA66, PC, peek, glass fiber reinforced Reny, PPS, fluororesin PTFE, PFA and PVD. 

Corrugated gasket, also known as wave gasket, is a kind of regular wavy circular sheet. It is generally used to prevent loosening and slow impact. It needs to have good elasticity and impact resistance. 1- Classification by use: (1) three wave washer A and common type B, bearing (2) single wave washer2- Classification by material 1. Carbon spring steel 2. Stainless steel

EPDM composite waterproof metal washer, which is generally used in conjunction with self tapping screws at the end of the drill. There are stainless steel 304 316 and carbon steel metal composite EPDM in black, gray, red, blue, white, etc. Advantages of (EPDM) rubber sealing ring:1. Excellent aging resistance.2. Excellent chemical stability.3. It has excellent compression deformation resistance and compression stress relaxation resistance.4. It has high elasticity.    

Rubber O-ring is a device used for piston sealing in reciprocating hydraulic cylinder, which is made of polyurethane TPU, CPU and rubber. Excellent sealing performance and high working life. The working life of dynamic pressure seal is 5-10 times higher than that of conventional rubber seal products, up to tens of times. Under some conditions, it can have the same life as the sealing matrix.It is mainly used in the occasions requiring sealing. Classification of rubber O-ringsIt mainly includes uhso ring, uhpo ring, uno ring, DHO ring, piston rod O ring, high temperature resistant O ring, high pressure resistant O ring, corrosion resistant O ring and wear-resistant O ring. The rubber O-ring still plays a good role in sealing and damping in the environment of oil resistance, acid and alkali resistance, abrasion resistance, chemical erosion, etc. Rubber O-ring is one of the most widely used seals in hydraulic and pneumatic transmission systems.    

Brass washer refers to the part between the connected part and the nut. Generally, it is a flat brass alloy ring, which is used to protect the surface of the connected part from scratch by the nut and disperse the pressure of the nut on the connected part. Brass washer category: flat washer, spring washer, square bevel washer, high-strength washer, locating washer. Brass washer standards: German standard (DIN), British Standard (BS), French Standard (NFE), Australian standard (as), American Standard (uss/sae). Surface color of brass washer: zinc plating (ZP) (yellow zinc, blue white zinc), black boiling (black), heat zinc (HDG), brass grades include H59 national standard brass row, H62 environmental protection brass strip and H65 Brass flat strip. Size: m2-m64 or customized size according to the drawing.    

The anti slip dishwasher includes single-sided tooth washer and double-sided tooth washer. The double-sided tooth anti-skid washer is also called anti-skid, safety and locking washer. The tooth surface safety washer solves the safety problem of screw connection. The quality of double-sided tooth lock washer shall strictly comply with jb/zq4340 and din9250 standards. The material is made of high-quality spring steel 65Mn. It can also be made of special materials, such as 60Si2MnA, phosphor bronze and stainless steel. There are s series and vs series of double tooth disc spring lock washers. The unique performance of the tooth disc spring lock washer is provided by the tooth surface, which solves the safety problem of bolt connection. After the washer is connected with the bolt, the friction resistance is increased to prevent the bolt from loosening after vibration. S series is standard load and vs series is medium load. Application: precision optical instruments, machinery, automobiles, aircraft and other high-end products. Surface treatment: bluing, electroplating, electrophoresis and mechanical galvanizing.
