Manual screwdriver set Wiha 40410 One-way screwdriver

The Wiha 40410 One-way screwdriver set is a compact manual tool set containing nine one-way screwdrivers designed for precise fastening tasks. The set weighs 240 g and combines a ball-end design on the tips for angled access with a durable, chrome-plated L-key surface to resist corrosion. Keys are organised in a space-saving holder for convenient storage and transport.

Advantages

The ball end allows access to screws at angles up to 25°, improving reach in confined or awkward positions. High-quality chrome plating on the L-key surface increases durability and resists corrosion, lowering long-term replacement costs. The compact, organised design saves space and keeps all standard keys accessible, while the short side of the keys improves accessibility for close-up work.

How to use

Select the appropriate one-way screwdriver from the holder and insert the tip into the screw head. Use the ball-end feature to engage screws at angles up to 25° when direct access is restricted. Apply steady torque on the key; use the short side for better control in close quarters. After use, return the keys to the organiser to maintain order and protect tips from damage.

Recommendations

For long-term performance, keep the chrome-plated surfaces clean and dry; avoid exposure to corrosive chemicals. Use the correct size key for each screw to prevent rounding and maintain the one-way function.
