The Wera 9 Piece Stainless Steel Colour Coded Ball End Hexagon Allen Key Set provides a professional metric hex key solution designed specifically for use with stainless steel fasteners, where preventing cross-contamination rust is essential. Constructed entirely from stainless steel, these L-keys eliminate the risk of transferring extraneous rust to stainless fixings — a common problem when using standard carbon steel hex keys. Wera’s Hex-Plus profile increases the contact surface area inside the screw head, significantly reducing the notching effect that causes rounding and damage to socket head screws over time. Each key features a ball end on the long arm, allowing the tool axis to be angled away from the fastener — ideal for working in restricted or awkward spaces where straight-on access isn’t possible. The colour-coded sleeves on each key make size identification fast and reliable, even in poor lighting conditions or when wearing gloves in cold environments. The nine keys are housed in a wear-resistant clip fastener, keeping the set organised and the correct key to hand on site. This set is particularly well suited to marine, food processing, and architectural applications where stainless fasteners are standard and rust contamination must be avoided.
