Gibraltar Z9450SET Spherical Washer Assembly 1/4 in

Product Description

The GIBRALTAR Z9450SET is a spherical washer assembly designed for use with 1/4 inch bolts. The set includes both a male and female spherical washer, allowing the fastener to seat at an angle and distribute load evenly across misaligned or non-parallel surfaces. Both components are manufactured from 12L14 grade case hardened steel and finished in black oxide for corrosion resistance. The female washer measures 5/16 inches inside diameter with a 5/8 inch outside diameter. The male washer measures 9/32 inches inside diameter with a 5/8 inch outside diameter. Washer thickness is 3/16 inches with a 3/4 inch radius. Combined assembly weight is 0.01 pounds.

Spherical washer assemblies like the Z9450SET are commonly installed in structural bolted connections, machinery mounts, and mechanical assemblies where bolt axes are not perfectly perpendicular to the bearing surface. They are used in industrial, commercial, and trade applications including HVAC equipment mounting, electrical panel support structures, and general mechanical installations. The self-aligning design compensates for angular misalignment, reducing stress concentration at the bolt head or nut bearing surface. Licensed technicians and maintenance trades install these as part of equipment fastening assemblies.

Key Features

• Spherical mating surfaces allow angular compensation for misaligned bolt installations
• 12L14 grade case hardened steel construction for strength and wear resistance
• Black oxide finish provides mild corrosion protection and reduces light reflection
• Female washer: 5/16 inches inside diameter, 5/8 inches outside diameter
• Male washer: 9/32 inches inside diameter, 5/8 inches outside diameter
• Sold as a matched set — male and female washers included together

Compatibility

Designed for use with 1/4 inch bolts in applications requiring spherical load distribution across angled or non-parallel bearing surfaces.

Installation Notes

Install with the concave face of the female washer facing the convex face of the male washer. Position the assembly between the bolt head or nut and the bearing surface so the spherical faces mate correctly. Torque fasteners according to the equipment manufacturer specifications and applicable mechanical codes. Inspect mating surfaces for debris before installation to ensure proper seating.
