The Wera 950PKL SZ N 13 Piece BlackLaser Hex Key Set Imperial is a professional-grade L-key set designed for use with imperial hexagonal socket screws, supplied in a robust clip holder for organised, ready-to-hand storage. At the heart of this set is Wera's Hex-Plus profile, which increases the contact surface area within the screw head. This significantly reduces notching and the risk of damaging the screw recess — a common frustration when working with worn or tight fixings on machinery, automotive applications, or imported equipment using imperial fasteners. The ball-end on the long arm allows work at angles, making it well suited to restricted or awkward installation positions where straight-on access is not possible. The BlackLaser surface treatment provides strong protection against corrosion and extends the service life of each key — particularly valuable in workshop, outdoor, or high-humidity environments. Each L-key features laser-engraved size markings that resist wear, ensuring sizes remain legible throughout the tool's working life. The clip holder is made from wear-resistant material, keeping all 13 keys securely in place while allowing quick individual removal during use.
