Draper Extra Long Hexagon Allen Key Metric

The 17mm Draper Extra Long Hexagon Allen Key is engineered for specialist heavy industrial applications where large metric socket head fixings are standard. This substantial size is commonly found in major plant machinery, heavy construction equipment, large-scale structural assemblies, and civil engineering projects where exceptional fastening capability is essential. Constructed from chrome vanadium steel that's been hardened and tempered, this key delivers exceptional strength and resistance to deformation under extreme torque loads. The chemically blacked protective finish provides lasting corrosion protection in the most demanding industrial environments, whilst chamfered ends facilitate accurate socket head engagement. The extra-long profile ensures outstanding reach for deeply recessed large fasteners and delivers the considerable leverage necessary to handle high-torque operations with confidence and control.
