Nut Driver Bit Wiha 04636

The Wiha 04636 nut driver bit is a precision fastening accessory made from high grade chrome-vanadium steel, through hardened for durability. It has a hexagonal shank of 25.4 / 4 mm (1/4") and a total length of 55 mm, with an integrated strong permanent magnet to ensure a secure hold on screws and nuts. The bit is lightweight (19.5 g) and intended for use in trade, industry and general mechanical and electrical fastening tasks.

Advantages

Manufactured from through-hardened chrome-vanadium steel for long service life, the Wiha 04636 nut driver bit provides accurate torque transfer via its precisely formed hex profile. The standardized 1/4" (6.3 mm) drive (DIN 3126 / ISO 1173, style E) ensures compatibility with common bit holders and power tools. An integrated strong permanent magnet improves handling and prevents fastener loss during assembly.

Suitable for

• Assembly and disassembly of hex nuts and bolts in trade and industry
• Mechanical and electrical installation work
• Work with power drivers and bit holders using a 1/4" (6.3 mm) drive

How to use

Insert the Wiha 04636 nut driver bit into a compatible 1/4" bit holder or power driver. Align the hex profile with the nut or bolt head and apply steady rotational force. The permanent magnet helps hold the fastener in position; ensure the bit is seated securely on the fastener before applying torque. After use, store the bit in a designated holder or case to protect the tip and maintain the magnet's effectiveness.

Usage recommendations

Use with appropriate torque settings to avoid rounding hex fasteners; inspect the bit for wear before use and replace if the hex profile shows deformation or significant wear. Avoid exposure to corrosive environments to preserve material hardness and magnet strength.
