Wera 3950 PKL/9 SB Hex-Plus Stainless 9 Piece Allen Key Set - 05073544001

Wera 3950 PKL/9 SB Hex-Plus stainless steel hex key set (9 piece, 1.5–10mm) – 05073544001

The Wera 3950 PKL/9 SB 05073544001 hex key set is a stainless steel L-key set designed for driving hexagon socket screws, helping reduce the risk of extraneous rust transfer when working with stainless fasteners. It’s a practical choice for fitters and maintenance engineers who want reliable keys that are easy to identify and keep organised.

Using the Wera Hex-Plus profile, this Allen key set is shaped to increase contact with the screw head for more secure drive engagement, while the ball-end on the long arm supports angled access for “around the corner” screwdriving.

Key Features

• Stainless steel construction: Helps prevent transfer of extraneous rust onto stainless screws during assembly and maintenance.
• Hex-Plus profile: Designed to provide a larger contact surface in the screw head to reduce the notching effect and minimise wear.
• Ball-end on long arm: Enables angled access to fasteners for easier work in confined or awkward positions.
• Size markings: Makes it quicker to select the correct key when working across multiple fastener sizes.
• Wear-resistant clip fastener: Keeps the L-keys secure and accessible for organised tool storage.
