Product Overview

It is generally used as a component that is cushioned at the workpiece connector and plays a role of precise adjustment of the clearance on the cushioned part.
It can also be used to protect the surface of the connected part from being scratched by the nut and disperse the pressure generated by the nut on the connected part.

Product Features

Feature 1: There is a wide range of options for inner and outer diameters and thickness, and the thickness can be specified in 0.1mm increments.
Feature 2: High-precision products made by cutting and machining can realize high-precision spatial adjustment.
Feature 3: Compared with standard washers, metal washers will not be dented after the connected part is screwed in due to the locking, and cause the bolts to loosen.
Feature 4: Compared with standard stamped washers, metal washers increase the friction with the mounting part, which can prevent loosening.

Usage Method

Example of use for securing the seat surface
■The bolt connection is stable.


Example of use for anti-loosening			Example of use for reinforcement of soft materials
■ By increasing the seat surface to increase friction, it is not prone to loosening.			■ Prevent the bolts from sinking in.


Example of use as spring washer

Precautions

①When D=16 or less, chamfer C is 0.2 or less.
When D=16.5 or more, chamfer C is 0.5 or less.
②Metal washer is a turned product, not a stamped part.
③When the relative humidity of the operating environment is high and certain anti-rust ability is required, please choose products with electroless nickel plating surface treatment or stainless steel SUS3 series materials.
④When the operating environment requires certain abrasion resistance and hardness for metal washers, please give priority to metal washer quenched products.
