Draper 33529 Metric Hexagon Key 4.0mm

This product is a Draper 4567-MM/B 4.0 mm metric hex key designed for precise tightening and loosening of hexagonal fasteners. Made from hardened and tempered chrome vanadium steel, it provides durability and strength for a range of DIY and home improvement tasks. The tool features a chemically blacked protective coating and chamfered ends to facilitate easier insertion and improved access to socket head cap screws. With a 4.0 mm size, it is compatible with hexagonal fasteners of that dimension and suitable for use with other tools that accept hex keys. Its design supports reach into tighter or awkward angles, enabling operations on furniture assemblies, bicycles, and machinery where space is limited. The combination of robust material, protective finish, and thoughtful geometry aims to deliver reliable performance in common assembly and maintenance applications while minimizing the risk of damaging fasteners when used with appropriate torque.
