De-sta-co 905-M M8 Clamp Spindle Assembly 2.5 in Oal

Product Description

The DE-STA-CO 905-M is an M8 carbon steel clamp spindle assembly designed for use with straight-line action clamps. It features an internal compression spring head tip that provides consistent workpiece contact and helps absorb minor variations in part height during clamping operations. The spindle has an overall length of 2.5 inches and a tip surface diameter of 0.88 inches. A zinc-plated finish provides corrosion resistance for general shop and production environments. Jam nuts are included for secure positioning along the clamp body. Mechanical assembly technicians and tooling specialists typically install and adjust this component on fixturing and workholding systems.

This spindle assembly is suited for production fixturing, welding fixtures, machining setups, and assembly jigs that use straight-line action toggle clamps. The internal compression spring head tip is particularly useful in applications where slight part-to-part height variation is present, allowing the tip to maintain contact pressure without requiring manual spindle readjustment between cycles. It is intended for light-to-medium duty clamping applications in industrial and manufacturing environments.

Key Features

• M8 thread size for direct installation into compatible straight-line action clamp bodies
• Internal compression spring head tip accommodates minor workpiece height variation
• Carbon steel construction with zinc-plated finish for corrosion resistance
• 2.5-inch overall length suits standard spindle depth requirements
• 0.88-inch tip surface diameter provides broad contact area on workpieces
• Includes jam nuts for secure spindle position lockdown

Compatibility

Designed for use with straight-line action toggle clamps requiring an M8 threaded spindle assembly with an internal compression spring head tip.

Installation Notes

Installation is performed by threading the spindle into the clamp body and adjusting to the correct extension before locking the jam nuts. Always release clamp pressure and de-energize any associated pneumatic or hydraulic systems before servicing spindle components. Use a wrench on the jam nuts to secure spindle position after final height adjustment. Verify tip contact is centered on the workpiece surface before returning the fixture to production.
