De-sta-co 604-SS Straight Line Action Clamp 400 Lb

Product Description

The DE-STA-CO 604-SS is a standard straight line action clamp built from stainless steel and rated for a 400 lb (1779.29 N) load capacity. It delivers linear clamping force through a round plunger with 1.5 inches of travel and a 0.44 inch diameter, making it well suited for fixturing, welding, and assembly applications where consistent, repeatable hold-down force is required. The clamp ships with a jam nut and features internal plunger threading sized at 5/16-18. Licensed tradespeople and fixture builders working in industrial or manufacturing environments will find the stainless steel construction appropriate for corrosive or wash-down conditions.

This clamp is used in jig and fixture assemblies, production tooling, and workholding setups across light manufacturing, fabrication, and automation environments. The mounting plate base allows bolt-down installation to flat surfaces or fixture plates. The straight handle style suits applications where direct, in-line actuation is preferred. At 4.95 inches overall length and 4.16 inches overall height, the 604-SS fits into compact fixture layouts without sacrificing clamping authority.

Key Features

• 400 lb (1779.29 N) rated load capacity for reliable hold-down force
• 1.5 inches plunger travel with 0.44 inch round plunger diameter
• Stainless steel construction suitable for corrosive and wash-down environments
• Mounting plate base for flat-surface bolt-down installation
• Internal plunger thread size 5/16-18 with included jam nut for position adjustment
• Maximum mechanical advantage of 26:1 (pulling) and 45:1 (pushing)

Compatibility

Designed as a standard straight line action clamp for use in industrial jig, fixture, and workholding applications requiring a stainless steel, mounting plate base clamp with 400 lb load capacity.

Installation Notes

Installation is typically performed by fixture builders or maintenance technicians using standard hand tools. Secure the mounting plate base to a flat, rigid surface using appropriately rated fasteners through all base mounting holes. Adjust plunger depth using the 5/16-18 internal thread and lock position with the included jam nut before putting the clamp into production. Verify that the clamping force does not exceed the rated 400 lb capacity for the intended application.
