Angle Clamps

Common types include fixed 90° corner clamps, adjustable/multi-angle clamps, bar-style corner clamps, and magnetic angle clamps; choose fixed or bar-style clamps for precise 90° joints in woodworking, adjustable or multi-angle clamps for compound or non-90° joints, and heavy-duty metal or magnetic clamps for metalworking and welding

Match the clamp throat depth and jaw opening to the thickness and dimensions of your workpieces; hobby and light woodworking often use clamps with 1–4 inch openings, while professional wood and metalwork may need 6 inches or more and sturdier jaws for larger stock

Look for hardened steel or cast-iron jaws and machined mating faces for accuracy, corrosion-resistant finishes or plated components for longevity, and solid screw or quick-release mechanisms rather than thin stamped metal for repeated use

Clamping force matters for holding pieces without slipping; screw-style or ratcheting mechanisms provide higher, adjustable force for heavy work, while spring or plastic-bodied clamps are suited for light alignment and delicate surfaces

Many clamps include removable or built-in protective pads; when none are provided, add thin rubber, leather, or wooden pads between the jaw and the workpiece to prevent dents and scratches

Keep moving parts clean of dust and metal filings, periodically lubricate screw threads with light oil, inspect pads and replace if worn, and store clamps dry to avoid rust or corrosion

Angle clamps commonly range from budget options under $25 to heavy-duty models over $100; spend more when you need precise machined faces, higher clamping force, durable metal construction, or specialty features like multi-angle adjustment for professional or frequent use
