Pins: Dowel, Cotter and Specialist Fixing Pins

Pins are simple yet vital fasteners used across woodworking, metalwork and machinery. From dowel pins that align joints to cotter pins that secure wheel nuts, choosing the right pin ensures reliable assembly and easy maintenance.

Common pin types and applications

Dowel pins are perfect for aligning parts in cabinetry and furniture. Split or cotter pins lock nuts and bolts in place, while taper and roll pins provide shear-resistant joints in mechanical assemblies. Material and finish affect longevity, especially in outdoor or damp environments.

Buying tips and practical uses

• Dowel pins: solid wooden or steel dowels for precise alignment in joinery.
• Split/cotter pins: quick to fit and ideal where regular removal may be required.
• Spring and roll pins: deliver tensioned fits for rotating assemblies.
• Materials: choose stainless steel for moisture-prone areas and hardened steel where strength is essential.

Small jobs often need a variety pack to cover common sizes; larger projects benefit from buying by length or diameter in bulk. Look for clearance sets if you need many pins at once, but avoid used pins for critical safety components unless inspected and certified. Proper sizing and the right tool for insertion will prevent damage and extend the life of the joint.
