Spherical Washer / Stop Washer

Spherical Washer is a metal washer applied to bolt, nut and anchoring connection positions. It features a spherical or conical shape with a through hole in the middle, which can deliver stable pressure-bearing support during tightening and installation. This product is applicable to working conditions where mounting surfaces have slight angular deviations, joint surfaces are not completely flat, or enhanced compression stability is required. It helps relieve concentrated local stress and enables firmer fitting between fasteners and connecting components. Spherical washers are widely used in industrial and mining equipment, mine support, rail fittings, steel structure connections, heavy machinery assembly and other scenarios. They can be customized in accordance with bolt specifications, hole diameters, outer diameters, thicknesses, materials and surface treatment requirements, and are suitable for engineering projects, equipment maintenance and bulk procurement of spare parts.
