Gibraltar 42741G Female Spherical Washer 12L14 Steel

Product Description

The GIBRALTAR 42741G is a female spherical washer machined from 12L14 case hardened steel with a black oxide finish. It is designed to provide self-aligning bearing contact between a fastener and a mating surface, compensating for angular misalignment in bolted assemblies. The 5/16 inch female inside diameter accepts a 1/4 inch nut screw size, and the 5/8 inch outside diameter seats against a matching spherical surface. The black oxide finish provides mild corrosion resistance and a consistent appearance. This washer is sold individually and must be ordered in multiples of five.

Female spherical washers are used in structural, mechanical, and industrial fastening applications where bolt holes are not perfectly perpendicular to the bearing surface. Common install scenarios include machinery mounts, structural steel connections, and equipment bases where even load distribution and angular compensation are required. This part follows inch system of measurement and conforms to TCMAI fastener standards, making it suitable for precision mechanical assemblies in manufacturing and maintenance environments.

Key Features

• 12L14 case hardened steel construction for strength and machinability
• Black oxide finish for mild corrosion resistance
• 5/16 inch female inside diameter fits 1/4 inch nut screw size
• 3/4 inch radius for self-aligning spherical contact
• 1/32 inch chamfer for guided seating during assembly
• Conforms to TCMAI fastener standard

Compatibility

Designed as an OEM-style replacement or component-level addition for bolted assemblies requiring inch-series female spherical washers with a 5/16 inch inside diameter and 5/8 inch outside diameter.

Installation Notes

Installation is performed by mechanical technicians or maintenance personnel as part of a bolted assembly. Always de-energize or isolate equipment before disassembling fastened joints under load. Use the correct torque wrench and follow the assembly specification for the host application. Pair with a matching male spherical washer for full angular compensation function.
