Brass Locking Washer Eco Chromium-Free Passivated Anti-Rotation Brass Retaining

Our brass locking washer, also named anti-rotation brass tab retaining washer, is a precision stamped flat metal component manufactured from high-purity brass raw sheet. Raw brass plate is processed with high-speed precision stamping to form the designated outline and positioning structure, specially designed to deliver anti-rotation, limiting and locking effects during equipment assembly.
After stamping forming, all brass washers are put into vibratory polishing equipment to remove sharp edge burrs and smooth all contour edges. Afterwards, every washer undergoes eco-friendly chromium-free passivation treatment, which forms a protective film on brass surfaces to enhance oxidation resistance, preserve natural brass luster and satisfy global export environmental standards.
As a professional stamped hardware manufacturer, we supply full OEM custom service for this brass locking washer and all other stamped brass tab washers. Customers may submit 2D/3D engineering drawings or physical sample washers to customize thickness, outer dimensions, tab shapes, dimensional tolerances and surface treatments to match locking and anti-rotation assembly requirements of precision devices. All custom brass retaining washers maintain consistent flatness and dimensional stability for small prototype batches and large mass production alike.
