De-sta-co 317-S Toggle Clamp Vertical 400.16 Lb Flanged Base

Product Description

The DE-STA-CO 317-S is a manual hold-down toggle clamp designed for vertical clamping applications in industrial workholding, fixturing, and assembly operations. Built from carbon steel with a straight red handle, this unit delivers a holding capacity of 400.16 lb (1780 N) with a 60-degree handle movement arc and a 185-degree bar opening. The flanged base provides a stable mounting platform with eight mounting holes, making it well suited for permanent fixture installations where repeatable, positive clamping force is required. A bolt retainer is included. Licensed machinists, tool-and-die technicians, and fixture builders are the typical installers.

The 317-S fits standard workholding and production fixturing setups in light manufacturing, welding positioners, and machining operations where a solid-bar, closed-end vertical clamp is needed. The flanged base allows direct surface mounting to fixture plates or work tables. With an overall height of 5.28 inches, a height under bar of 2.68 inches, and a front-of-base to toggle tip distance of 3.20 inches, this clamp accommodates workpiece thicknesses typical of sheet metal and light structural fixturing. The solid bar style provides uniform clamping pressure across the contact surface without pivot-point gaps.

Key Features

• 400.16 lb (1780 N) holding capacity for firm, repeatable clamping in production environments
• 185-degree bar opening allows easy workpiece loading and unloading
• 60-degree handle movement arc for quick actuation in tight fixture layouts
• Flanged base with eight mounting holes for rigid, permanent fixture mounting
• Solid bar with closed bar end provides even contact and prevents workpiece slipping
• Carbon steel construction throughout with straight red handle for fast visual identification
• Bolt retainer included for secure hardware retention during assembly

Compatibility

Designed as an OEM-style hold-down toggle clamp for use in industrial workholding fixtures, welding jigs, and assembly tooling that require a vertical-action, flanged-base clamp with a solid bar.

Installation Notes

Installation is typically performed by fixture builders or tool-and-die technicians using standard hand tools. Mount the flanged base to a rigid fixture plate using fasteners sized for the 0.27-inch mounting holes. Verify the workpiece thickness falls within the height-under-bar clearance before securing the clamp. Always confirm the toggle mechanism is fully locked over-center before applying load to the fixture.
