Gibraltar 7283-7293-G Spherical Washer Assembly 5/32 in

Product Description

The GIBRALTAR 7283-7293-G is a stainless steel spherical washer assembly designed to accommodate a 5/32-inch bolt and provide angular compensation between mating surfaces under load. The assembly consists of a female cup washer and a male spherical washer that mate together to allow self-alignment, reducing stress concentrations at the fastener head or nut. Manufactured from 303-grade stainless steel, the assembly offers corrosion resistance suitable for demanding service environments. The female washer measures 3/16 inches inside diameter by 3/8 inches outside diameter, and the male washer measures 5/16 inches outside diameter with a thickness of 13/64 inches and a 1/32-inch radius. Total assembly weight is 0.01 pounds.

Spherical washer assemblies of this type are used across mechanical, structural, and industrial applications where bolt-hole misalignment or angled mounting surfaces are present. Common installation scenarios include bracket and frame assemblies, structural steel connections, and precision machine bases where fastener self-alignment is required to distribute clamping load evenly. The compact 5/32-inch bolt size makes this assembly appropriate for light-duty mechanical subassemblies and instrumentation hardware.

Key Features

• 303-grade stainless steel construction for corrosion resistance in wet or chemically exposed environments
• Spherical mating surfaces allow angular self-alignment between bolt and clamping surface
• Female inside diameter of 3/16 inches with 3/8-inch outside diameter for stable seating
• Male outside diameter of 5/16 inches with 13/64-inch thickness for consistent load distribution
• 1/32-inch spherical radius provides controlled angular compensation
• 1/16-inch chamfer for ease of assembly and alignment

Compatibility

Designed for use with 5/32-inch bolts in applications requiring a spherical washer assembly with a 3/16-inch inside diameter and 303-grade stainless steel construction.

Installation Notes

Install with the male convex washer seated against the female concave washer, ensuring both mating surfaces are clean and free of debris before assembly. Torque the fastener to the specification required by the parent assembly design — do not exceed the rated capacity for the bolt size. Power down or de-energize any equipment before servicing fastener assemblies in electrical or mechanical enclosures. Standard hand tools and calibrated torque wrenches are appropriate for installation.
