Corner Clamps

About Corner Clamps

Corner clamps are indispensable workshop tools that hold two workpieces at precise right angles during assembly. Whether you're joining mitred picture frames, assembling cabinet carcasses, or fabricating steel sections, these clamps eliminate the challenge of holding materials in position whilst fastening. MyToolShed.co.uk stocks a comprehensive range from leading manufacturers including Bessey, Sealey, DeWalt, Stanley, and Record, covering everything from delicate frame-making to heavy-duty metalworking applications.

The category includes standard woodworking corner clamps with adjustable jaws for various material thicknesses, specialist welders angle clamps featuring heat-resistant copper-plated components that withstand welding spatter, and multi-piece clamping sets for simultaneous corner assembly. Models range from compact units for picture framers to robust fabrication clamps capable of handling substantial steel sections, with features like quick-release mechanisms, swing jaws, and integrated measuring guides enhancing versatility across professional workshops and DIY projects.

Applications

Corner clamps serve a diverse range of trades and applications:

• Carpenters and Joiners: Assembling cabinets, drawer units, boxes and furniture with accurate right angles
• Picture Framers: Creating professional mitred joints in frames and mirror surrounds
• Welders and Metal Fabricators: Holding steel sections at precise angles during tack and full welding operations
• Shop Fitters: Building display units, shelving systems and bespoke retail fixtures
• Kitchen and Bathroom Fitters: Assembling flat-pack units and creating custom cabinetry on site
• Window Fitters: Assembling and repairing timber window frames
• DIY Enthusiasts: Home projects from shelving units to garden planters
• Model Makers: Creating accurate scale models and prototypes requiring precise angles

Choosing The Right Corner Clamps

Application Type: Select clamps appropriate to your materials and processes. Specialist welders angle clamps with copper-plated components are essential for fabrication work, whilst standard models suit most woodworking. Multi-piece sets offer better value when assembling frames or boxes requiring simultaneous corner clamping.

Jaw Capacity: Check the maximum material thickness the clamp accommodates. Most models handle 10-70mm sections, whilst heavy-duty versions exceed 100mm for substantial timber or steel work.

Build Quality: Professional tradespeople benefit from robust cast aluminium or steel construction from brands like Bessey or DeWalt that withstand daily site use. MyToolShed.co.uk stocks both professional-grade and budget-friendly options for occasional DIY projects.

Clamping Mechanism: Quick-release systems save time on repetitive tasks, whilst fine adjustment screws provide precision for critical work. Swing jaw designs offer flexibility with irregular shapes or angled components.

Safety Information

Secure Positioning: Ensure workpieces are fully seated in clamp jaws before tightening. Apply pressure gradually and verify alignment before drilling or fastening to prevent workpiece slippage.

Welding Applications: Only use specialist welders angle clamps rated for high-temperature work. Position clamps away from the direct welding zone where possible, allow adequate cooling time, and always wear appropriate PPE including gloves and face protection in compliance with HSE guidelines.

Avoid Over-Tightening: Excessive pressure can crush soft materials, crack joints, or damage clamp mechanisms. Apply only sufficient force to hold workpieces securely without causing deformation.

Frequently Asked Questions

Can I use standard corner clamps for welding?
No, standard corner clamps aren't suitable for welding as heat and spatter damage plastic components and seize metal threads. Always use specialist welders angle clamps with copper-plated threads and all-metal heat-resistant construction designed specifically for fabrication environments.

What jaw capacity do I need for typical carpentry work?
Most woodworking applications require clamps handling 20-70mm material thickness. Check the manufacturer's specifications to ensure the jaw capacity suits your typical workpiece dimensions before purchasing from MyToolShed.co.uk.

Do corner clamps guarantee perfect 90-degree angles?
Whilst corner clamps hold workpieces at approximately 90 degrees, always verify angles with an engineer's square or digital angle finder before final fastening. Workpiece irregularities or clamp wear can result in slightly out-of-square assemblies, so verification ensures professional results.
