3 mm Hex Key

A 3mm hex key, or Allen wrench, is slightly larger than the 2mm version and is used to drive screws or bolts with a 3mm hexagonal socket.

Common applications include furniture assembly, electronics, bicycles, and medium-sized mechanical fasteners.

Working Principle:

• Hexagonal Shape: The hex key's cross-section matches the hexagonal recess of the fastener, ensuring a secure fit and preventing slippage.
• Material Strength: Made from durable materials like steel or alloy to handle the force exerted during use.
• Angles and Access: Available in L-shaped or T-shaped designs, allowing access to fasteners in various positions and orientations.
