De-sta-co 905 Clamp Spindle Assembly 5/16-18 Thread

Product Description

The DE-STA-CO 905 is a replacement spindle assembly designed for use with Straight Line Action clamps. It features a 5/16-18 threaded spindle with a zinc-plated finish and an overall length of 2.50 inches. The assembly includes an internal compression spring head tip with a flat steel tip cap and a jam nut for secure positioning. It mounts via screw and is intended for use by machinists, fixture builders, and production tooling technicians who maintain or upgrade clamping workholding equipment.

This spindle assembly is suited for industrial and manufacturing environments where Straight Line Action clamps are used in jigs, fixtures, and workholding setups. It is a direct-fit service component for maintaining clamp performance in production or assembly line applications. The zinc-plated finish provides corrosion resistance appropriate for shop-floor conditions. The included jam nut allows precise adjustment and locking of spindle depth during setup.

Key Features

• 5/16-18 thread size for compatibility with standard Straight Line Action clamp bodies
• Overall length of 2.50 inches for proper reach and clamping depth
• Zinc-plated spindle finish for corrosion resistance in shop environments
• Internal compression spring head tip for consistent contact force
• Flat steel tip cap provides a stable, even clamping surface
• Includes jam nut for precise spindle depth adjustment and lockdown

Compatibility

Designed for use with DE-STA-CO Straight Line Action clamps requiring a 5/16-18 threaded spindle assembly replacement.

Installation Notes

Installation is performed by tooling and fixture technicians. Disengage and de-energize any associated clamping equipment before servicing spindle components. Thread the spindle into the clamp body by hand before tightening, and use the included jam nut to lock spindle position once the desired clamping depth is set. Avoid over-tightening the jam nut, which can distort the thread engagement.
