De-sta-co 507907 Flanged Washer 5/16 Inch Spindle

Product Description

The DE-STA-CO 507907 is a stainless steel flanged washer designed for use with 5/16 inch diameter clamp spindles. It features a 5/16-18 threaded bore, a hole diameter of 0.33 inches, an overall diameter of 0.88 inches, and a distance between flanges of 0.6 inches. This washer serves as a precision spindle accessory, providing a stable bearing surface and secure seating in toggle clamp and workholding applications. Its stainless steel construction resists corrosion and wear under repeated clamping cycles. Industrial maintenance technicians and machine builders are the typical installers.

This flanged washer fits 5/16 inch clamp spindle assemblies in industrial toggle clamp setups. It is commonly used in fixture tooling, welding jigs, and assembly line workholding equipment where consistent clamping force and spindle alignment are critical. The metric equivalent spindle diameter is M8, making it suitable for applications where inch and metric tooling overlap. Typical environments include manufacturing floors, fabrication shops, and automated assembly stations requiring reliable clamping hardware.

Compatibility

Designed as an OEM-style replacement or spare flanged washer for 5/16 inch diameter clamp spindles with 5/16-18 thread in toggle clamp workholding assemblies.

Installation Notes

Installation is typically performed by industrial maintenance technicians or tooling specialists. Ensure the clamp assembly is fully de-energized and relieved of clamping load before replacing spindle hardware. Use appropriate hand tools to thread and seat the washer evenly without cross-threading. Verify spindle alignment and washer seating before returning the fixture to service.
