Wera 3950PKL SZ 9 Piece Stainless Steel Ballend Hex Allen Key Set Imperial

The Wera 3950PKL SZ is a 9-piece stainless steel imperial hex key set designed for use with imperial hexagonal socket screws in environments where corrosion resistance is essential. Manufactured from stainless steel throughout, these L-keys eliminate the risk of extraneous rust transferring onto stainless fasteners — a common problem when carbon steel tools are used on stainless fixings. This makes the set particularly well suited to food processing, marine, and medical equipment applications where material contamination must be avoided. Wera's Hex-Plus profile distributes load across a larger contact surface within the screw head, significantly reducing the notching and rounding that can damage socket head screws over time. The long arm features a ballpoint end, allowing the tool axis to be angled away from the drive axis for access in restricted or awkward positions. Each key is clearly size-marked for quick identification, and the set is stored in a robust belt pouch for easy access on site.
