Gibraltar 42744G Female Spherical Washer 12L14 Steel

Product Description

The GIBRALTAR 42744G is a female spherical washer machined from 12L14 case hardened steel with a black oxide finish. Spherical washers are used in matched pairs or against mating surfaces to compensate for angular misalignment between a fastener and its bearing surface. The female component seats against the male spherical washer to allow controlled tilt and distribute clamping load evenly across the joint. This part measures 11/16 inches inside diameter by 1-3/8 inches outside diameter, with a 1-3/4 inch radius and a 1/32 inch chamfer. It is rated for a 5/8 inch nut screw size and a 1-3/8 inch nut flange diameter. Weight is 1 pound per unit.

This washer is suited for structural bolting, machinery mounting, and mechanical assemblies where shaft or fastener angularity is a concern. Common applications include beam connections, press frames, conveyor systems, and any bolted joint where the mating surfaces are not perfectly parallel. The inch-system dimensioning makes it compatible with standard SAE and unified fastener hardware. Installation is typically performed by millwrights, maintenance mechanics, or structural ironworkers working on industrial or commercial mechanical systems.

Key Features

• 12L14 case hardened steel construction for strength and wear resistance at the bearing surface
• Black oxide finish provides mild corrosion resistance and reduces light reflection in service environments
• 11/16 inches inside diameter fits standard 5/8 inch nut screw sizes
• 1-3/4 inch spherical radius allows angular compensation between fastener and mating surface
• 1/32 inch chamfer aids alignment and seating during assembly
• TCMAI fastener standard compliance

Compatibility

Designed for use with matching male spherical washers and standard 5/8 inch fastener hardware in inch-dimensioned mechanical assemblies.

Installation Notes

Spherical washers are installed as a matched female-male pair; verify the mating male washer radius matches before assembly. Clean contact surfaces before seating to ensure full bearing contact across the spherical interface. Torque fasteners according to the joint design specification for the application. Always de-energize or lock out any equipment before performing fastener service on machinery.
