Lincoln Electric KH907 C-clamp 5 in Extra Deep Forged Steel

Product Description

The LINCOLN ELECTRIC KH907 is a heavy-duty C-clamp built for demanding welding, fabrication, and metalworking applications. Constructed from forged steel, this clamp provides the structural integrity needed to hold workpieces securely under high clamping force. The extra deep throat design allows it to reach further into a workpiece than standard-depth clamps, making it especially useful when edge clearance is limited. With a maximum opening capacity of 5 inches and a copper-plated screw and spindle, the KH907 is well suited for professional trades that require reliable, repeatable clamping performance on heavy stock material.

This clamp is designed for use in welding shops, fabrication facilities, and field metalwork where a strong, extra-deep-throat C-clamp is required. It handles applications ranging from holding steel plate during tack welding to securing fixtures and workpieces on metal fabrication tables. The copper-plated spindle helps resist thread galling under repeated high-load use. Trade professionals including welders, ironworkers, and pipefitters will find this clamp appropriate for both bench and positional work where standard throat depth is insufficient.

Key Features

• Forged steel body and clamp material for heavy-duty strength and durability
• Extra deep throat design extends reach beyond standard C-clamp geometry
• 5-inch maximum opening capacity accommodates thick stock and layered assemblies
• Copper-plated screw and spindle finish resists galling and aids smooth operation under load
• Minimum opening of 0 inches allows clamping of flush or thin material

Compatibility

Designed as an OEM-style heavy-duty C-clamp for general welding, fabrication, and metalworking applications requiring extra deep throat clearance and a 5-inch maximum opening.

Installation Notes

C-clamps of this type are installed by hand and typically require no tools beyond the integrated screw mechanism. Ensure the workpiece and clamping surfaces are free of debris before applying clamping force to prevent slippage. Do not exceed the rated clamping capacity or use extension bars on the handle, as overloading forged clamps can cause sudden failure. Always position the clamp so clamping force is applied axially through the screw to avoid side-loading the throat.
