De-sta-co 624 Straight Line Action Clamp 700 Lb

Product Description

The DE-STA-CO 624 is a standard straight line action clamp designed for high-force workholding and fixturing applications in industrial and manufacturing environments. It delivers a rated load capacity of 700 pounds (3,113.76 N) and provides 2.63 inches of plunger travel, making it suitable for clamping a wide range of workpiece thicknesses. The clamp body is constructed from carbon steel and features a straight red handle with a mounting plate base for secure, stable installation. A jam nut is included to lock plunger position once set. Licensed machinists, toolmakers, and fixture builders are the primary installers of this type of clamp.

The 624 is used in jig and fixture setups, welding positioners, assembly lines, and machine tool applications where a repeatable, inline clamping force is required. The straight line action design transfers force directly along the plunger axis, which suits applications where lateral deflection must be minimized. The mounting plate base allows the clamp to be bolted directly to fixture plates, pallets, or weld tables. This clamp is well suited to both light production and heavy-duty workholding scenarios where consistent 700-pound holding force is required across repeated cycles.

Key Features

• 700-pound load capacity with 3,113.76 N equivalent force rating
• 2.63-inch plunger travel accommodates varying workpiece thickness
• Maximum mechanical advantage of 21:1 (pulling) and 49:1 (pushing) for efficient handle actuation
• Round plunger with 0.62-inch diameter and internal 3/8-16 thread for tip accessories
• Mounting plate base (3.0 inches long x 1.5 inches wide) for direct fixture-plate installation
• Jam nut included with 1-14 thread size for precise plunger depth adjustment and lockout
• Carbon steel construction for durability in industrial workholding environments

Compatibility

Designed as a standard OEM-style straight line action clamp consistent with industry number 624 specifications, compatible with fixture plates and tooling systems that accept mounting plate base clamps with 3/8-16 internal plunger thread accessories.

Installation Notes

Installation is typically performed by toolmakers or fixture engineers using standard hand tools and drill press equipment to mount the base plate to the fixture surface. Confirm that the mounting surface can support the full rated clamping load before use. Set plunger depth with the included jam nut and torque to a firm, wrench-tight condition without overloading the thread engagement. Do not exceed the rated 700-pound load capacity, and inspect the clamp mechanism for wear or deformation during routine maintenance intervals.
