Gibraltar 23050.0120 Female Spherical Washer 20mm Type D

Product Description

The GIBRALTAR 23050.0120 is a Type D female spherical washer designed for use with 20mm bolt assemblies in precision fastening applications. Manufactured from case hardened steel, this metric washer allows for angular correction of up to 3 degrees, compensating for minor misalignment between mating surfaces. It conforms to DIN 6319 standards, which establishes consistent geometry and load distribution requirements for spherical washers. The washer measures 23.2mm female inside diameter, 36mm female outside diameter, and 7.5mm thick. Licensed tradespeople and industrial assembly technicians install this component where rigid bolt connections require angular compensation to maintain even clamping force across joint surfaces.

This washer is suited for use in mechanical assemblies, structural connections, and machine mounting applications where bolt axes are not perfectly perpendicular to the bearing surface. It is typically paired with a convex male spherical washer of corresponding geometry to form a matched set. The DIN 6319 Type D designation specifies the female (concave) half of this pairing. Applications span industrial equipment, agricultural machinery, and structural steel fabrication where metric fastener standards are specified. The case hardened steel construction provides resistance to deformation under sustained clamping loads.

Compatibility

Designed for use with 20mm metric bolts in assemblies requiring DIN 6319 Type D female spherical washers. Intended to be paired with a corresponding DIN 6319 convex male spherical washer. No specific equipment model compatibility was provided with this product listing.

Installation Notes

Installation is typically performed by millwrights, industrial mechanics, or structural assembly technicians. Before servicing any bolted joint, ensure the assembly is depressurized and de-energized as required by the application. The spherical washer set should be oriented correctly — female (concave) face paired against the male (convex) face — to achieve proper angular compensation. Follow applicable torque specifications from the equipment manufacturer or relevant fastener standards for the 20mm bolt being used.
