Crescent Rings

Zeyao, a hardware fastener manufacturer with 19 years of experience, is equipped with over 160 production machines and a monthly output exceeding ten million pieces. We provide OEM/ODM customization services, covering a one-stop production solution from material selection and mold development to surface treatment.

A Crescent Ring is a specially shaped metal washer with an opening. It is commonly used for positioning and preventing loosening of screws, bolts, or shafts, providing elastic support and reliable clamping force within a confined space.

Unlike traditional round washers, the Crescent Ring's unique "half-moon shaped structure" automatically recovers some of its deformation after being compressed, serving to absorb shock, cushion, and prevent loosening.

Product Features:

Unique Structural Design: The Crescent Ring features a crescent-shaped arc design that generates continuous elastic force after bolt tightening, preventing thread loosening.

High Elasticity and Shock Resistance: Provides stable rebound force in mechanical vibration or thermal expansion environments, effectively preventing connection loosening.

Excellent Corrosion Resistance: Available in stainless steel, carbon steel, or surface-plated with zinc or nickel, adaptable to various operating environments.

Multiple Material Options: Aluminum, copper, stainless steel, carbon steel, spring steel, 65Mn elastic steel, etc., meeting lightweight or high-strength requirements.

Customized Production: Shape, thickness, curvature, and surface treatment can be customized according to customer drawings, dimensions, and application scenarios.
