Gibraltar Z9454SET Spherical Washer Assembly 3/8 in

Product Description

The GIBRALTAR Z9454SET is a spherical washer assembly designed for 3/8 inch bolt applications. It consists of a mated male and female washer pair that allows angular misalignment between a bolt and a clamped surface, distributing load evenly and reducing stress concentrations at the fastener seat. Constructed from 12L14 grade case hardened steel with a black oxide finish, this assembly offers good surface hardness and corrosion resistance suitable for general industrial and mechanical fastening work. The set is installed by licensed mechanics, millwrights, and maintenance technicians wherever precise load distribution is required at a bolted joint.

This spherical washer assembly is suited for applications in structural assemblies, machine mounting, conveyor systems, and other mechanical installations where bolt-to-surface angularity cannot be perfectly controlled. The black oxide finish provides mild corrosion resistance and a low-reflectance appearance appropriate for interior and protected exterior environments. It is sold as a single assembly set consisting of the male and female washer pair, packaged individually.

Key Features

• Spherical mating surfaces accommodate angular misalignment at the bolt seat
• 12L14 grade case hardened steel for improved surface hardness and wear resistance
• Black oxide finish for mild corrosion resistance and clean appearance
• Female inside diameter of 7/16 inches and male inside diameter of 13/32 inches for 3/8 inch bolt fitment
• 1/4 inch thickness with 1-1/4 inch spherical radius for controlled load distribution
• Sold as a complete male and female washer set, quantity one per package

Compatibility

Designed for use with 3/8 inch bolts. Suited as an OEM-style replacement or upgrade spherical washer assembly in mechanical and structural fastening applications requiring angular compensation at the bolt joint.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians. De-energize and lock out equipment before servicing any fastened assembly. Ensure the male washer seats against the bolt head or nut face and the female washer seats against the clamping surface, with the spherical faces mated together. Do not exceed the load ratings of the parent fastener or the structural assembly being joined.
