C.H. Hanson C-Clamps: Engineering Meets Endurance

When a clamp needs to hold fast under pressure — whether you're welding, fabricating, or working on an automotive repair — the tool in your hand matters. C.H. Hanson, a family-owned American tool company with roots stretching back to 1866, brings that same multi-generational commitment to quality into their lineup of C-clamps. These are not entry-level fastening tools — they are purpose-built, materials-conscious clamps designed for professionals and serious DIYers who refuse to compromise.

What Sets C.H. Hanson C-Clamps Apart

The defining feature across C.H. Hanson's C-clamp lineup is their patented self-adjusting locking mechanism. Rather than requiring manual screw adjustments for each workpiece, these clamps use a proprietary "Set & Forget" system: once you dial in your desired clamping pressure — from the lightest touch to an extreme hold — the jaws automatically adjust to grip any size object with equal, consistent force. This means no frustrating re-setting between cuts, no lost pressure, and no guesswork on the shop floor.

This one-handed operation design is a significant productivity advantage. Whether the material you're holding is thin sheet metal or a thick structural beam, C.H. Hanson's self-adjusting jaws lock on and hold. Swivel pad variants add even more versatility, protecting delicate workpiece surfaces while maintaining a firm, non-slip grip.

Materials Built for the Job

C.H. Hanson C-clamps are constructed from chrome molybdenum steel — an alloy known for its exceptional strength-to-weight ratio and resistance to deformation under stress. Some models also feature a durable nickel plate finish for added corrosion resistance, making them at home in both dry workshops and harsher environments. The re-engineered release lever is another thoughtful detail: it delivers a controlled, pinch-free release, reducing the risk of hand injury during repetitive use.

Product Range and Sizes

The C.H. Hanson C-clamp lineup includes a variety of sizes and configurations to match the task at hand. Common offerings include:

• 7-inch self-adjusting locking C-clamps — available in standard and swivel pad configurations, with a 2.5-inch jaw opening and 2.5-inch throat depth, ideal for mid-range clamping applications.
• 11-inch self-adjusting locking C-clamps — offering a 3-inch jaw opening and 3.75-inch throat depth for larger assemblies; also available with swivel pads for surface-sensitive work.
• Classic manual locking C-clamps — 6-inch and 11-inch models in a traditional style, with nickel plate finish and meeting ASME product specifications.

All models in the lineup back their build quality with a limited lifetime warranty, reflecting C.H. Hanson's long-standing confidence in the durability of their clamping tools.

A Legacy Brand You Can Trust at the Bench

C.H. Hanson has spent over 150 years manufacturing and sourcing tools designed to stand the test of time. Their C-clamps represent that same philosophy: innovate where it matters, use the right materials, and build something a tradesperson can rely on day after day. Whether you're in a fabrication shop, a body repair bay, or a home garage, a C.H. Hanson C-clamp earns its place at the bench.
