3950PKL Piece Stainless Steel Ballend Hex Allen Key Set Imperial

The Wera 3950PKL SZ is a professional-grade 9-piece imperial hex key set manufactured from stainless steel, designed specifically for working with stainless steel fasteners. This premium L-key set prevents extraneous rust contamination when fastening stainless screws, making it essential for applications where corrosion resistance is critical. The set features Wera's innovative Hex-Plus profile, which creates a larger contact surface within the screw head compared to conventional hex keys. This design significantly reduces notching effects and virtually eliminates the risk of damaging the screw recess, extending the working life of both the fastener and the tool. Each key incorporates a ball-end on the long arm, enabling angled access up to 25 degrees from the screwdriving axis for working in confined spaces or around obstructions. Size markings on each key ensure quick identification, whilst the included belt pouch keeps the set organised and readily accessible on site. This set is ideal for mechanical engineers, maintenance professionals, and contractors working with stainless steel assemblies in food processing, marine, pharmaceutical, or chemical environments where preventing ferrous contamination is paramount.
