Gibraltar 7284-7294-G Spherical Washer Assembly 3/16 in

Product Description

The GIBRALTAR 7284-7294-G is a stainless steel spherical washer assembly designed to accommodate a 3/16 inch bolt. This two-piece assembly consists of a male and female washer component that work together to compensate for angular misalignment between a bolt and the mating surface. The male component has an outside diameter of 3/8 inch and the female component has a 7/32 inch inside diameter and a 7/16 inch outside diameter. Material is 303 grade stainless steel, providing good corrosion resistance and machinability. Thickness is 15/64 inch with a 5/64 inch radius. This assembly is installed by maintenance technicians, millwrights, and mechanical tradespeople wherever joint alignment correction is needed.

Spherical washer assemblies are used in structural and mechanical fastening applications where the bolt and clamped surface are not perfectly parallel. Common scenarios include equipment mounting, machinery base plates, structural steel connections, and conveyor or frame assemblies. The 303 stainless steel construction makes this assembly suitable for environments with moderate moisture or mild corrosive exposure where carbon steel hardware would be unacceptable.

Compatibility

Designed as an OEM-style replacement or standard hardware component for mechanical and structural assemblies requiring a 3/16 inch bolt spherical washer set in 303 stainless steel.

Installation Notes

Installation is performed by qualified mechanical trades personnel following applicable fastener and structural assembly standards. Power down or de-energize any equipment before servicing fastened joints. The male and female washer components must be oriented correctly — convex face of the male piece nests into the concave face of the female piece — before torquing the bolt. Do not substitute components from mismatched washer sets, as mixed radii will not seat properly.
