Dimensions of type M spring washers(medium-width version）

In view of the locking effect of the stripe gasket, the thickness of the SKL-type self-locking gasket has been specified so that the corrective load is slightly lower than the pressure of Grade 8.8 screws. In this case, the pressure distribution on the parts to be tightened is slightly uneven. If the assembly of SKL-type tooth faces self-locking washers must make the gasket to achieve the maximum elastic reaction force, it is best to apply the appropriate smooth conical shims. SKL-type tooth faces self-locking washers in the installation of the strip marks conical shims, the concave surface must be squarely on the side of the tightened parts.
 Product Application:
SKL-type tooth faces self-locking washers are widely used in electronic appliances, electrical equipment, elevators, communications, locomotive manufacturing, rail transit, medical machinery support, and special equipment above, etc.
Main Material:
SKL French lock washer manufacturing all ordinary 65mn spring steel and SK5.SK7 imported high-quality carbon steel and 304.316 (A2.A4) stainless steel, etc., all products by strict elasticity hardening and hardness hardening treatment (including stainless steel products), strict control of the heat treatment process to ensure that each product meets the performance requirements. Carbon steel lock washers surface treatment of oxidation blackening, salt spray galvanized dehydrogenated, and zinc-magnesium special Dacromet coating treatment. Stainless steel lock washers surface treatment hardened and polished, color treatment.    

Product Main Functions.
1. When installing the gasket to the pressure level, it can ensure the stress distribution on the tightened parts evenly.
2. As the shims are striped, it prevents the threads of the screws or nuts from loosening.
3. Due to their elasticity, they compensate for the sinking of the assembled material and minimize pressure loss.
4. It is a disc-type improved product quality in accordance with the DIN6796 standard, The working principle is to use the tension generated by the rebound of the product after the force to play the role of anti-loosening and anti-slip.
