Designed for recessed socket screws commonly found in furniture and machinery, our Allen key sets provide secure, slip-free engagement. Made from hardened tool steel with a precise hexagonal profile, these L-shaped keys offer superior torque transfer. Available in both metric and imperial sizes, the set often comes on a compact, organised fold-out holder. Their simple, effective design makes them the go-to tool for assembling flat-pack furniture, bicycle maintenance, and adjusting appliances.
