Bessey STC-IHH15 Inline Toggle Clamp 450 Lb Flanged Base

Product Description

The BESSEY STC-IHH15 is a straight-line action inline toggle clamp rated for 450 lb of clamping load. It uses a round plunger with an internal M5 thread and 0.375 inches of plunger travel, giving technicians and fabricators precise, repeatable holding force in a compact footprint. The flanged base mounts to fixtures, jigs, and workholding setups using four mounting holes. The clamp body is carbon steel with a straight red handle for fast one-handed actuation. At 7.13 inches overall length and 1.26 inches overall height, this clamp fits tight fixture layouts without sacrificing rigidity or clamping performance.

This clamp is suited to light industrial and production environments where repeatable part positioning is required. Typical applications include welding fixtures, assembly jigs, woodworking setups, and CNC workholding stations. The inline toggle action is especially effective in straight-pull clamping scenarios where cam-action or horizontal-action clamps would interfere with adjacent components or tooling. It ships individually and is appropriate for both new fixture builds and replacement installations where an inline toggle clamp is already specified.

Key Features

• 450 lb rated clamping load for reliable part retention in production jigs
• 0.375 inches plunger travel with round plunger and internal M5 thread for adjustable pressure pad depth
• Flanged base with four mounting holes for secure fixture integration
• Carbon steel construction for durability in shop and light industrial environments
• Straight red handle enables fast, ergonomic one-handed operation
• Includes pressure pad cap for contact surface protection

Compatibility

Designed as an OEM-style replacement or direct-fit option for inline toggle clamp applications requiring a flanged-base, four-hole mount, straight-handle configuration with M5 internal plunger thread.

Installation Notes

Installation is typically performed by machinists, tool-and-die makers, or fixture builders using standard drill-and-tap or through-bolt mounting methods. Ensure the mounting surface is flat and that all four base mounting holes are fastened evenly to prevent rocking under load. Power down or de-energize any automated fixture before installing or servicing this clamp. Do not exceed the 450 lb rated load capacity, as overloading a toggle clamp can cause sudden release and potential workpiece ejection.
