Screwdriver Wera 868/4 IMP DC internal square 2 x 50 mm

Wera 868/4 IMP DC internal square 2 x 50 mm is a precision screwdriver designed for driving and removing fasteners with an internal square (Innenvierkant) drive. The tool features a 50 mm blade length that provides access to screws in confined spaces while maintaining secure engagement and accurate torque transfer. Its compact size makes it suitable for workshop, assembly and maintenance tasks where reliable handling and precise fit are required.

Advantages

The screwdriver is constructed to ensure consistent contact with internal square drives, reducing the risk of slipping or rounding. The 50 mm blade length offers a balance between reach and control, allowing access into recessed screwheads without sacrificing handling. The tool is compatible with applications that require precise torque transfer and a compact form factor for working in tight or obstructed areas.

Suitable for

• Assembly and disassembly of components with internal square fasteners
• Maintenance and repair in workshops and service environments
• Electrical and mechanical installations where short-reach drivers are required
• Situations requiring accurate engagement to avoid fastener damage

Key specifications

• Tip type: internal square (Innenvierkant)
• Tip size: 2 x 50 mm (square size × blade length)
• Blade length: 50 mm
• Drive compatibility: internal square fasteners
• Intended use: manual driving and removal of internal square screws

How to use

Align the internal square tip with the corresponding socket of the fastener, apply steady axial pressure and turn the handle to drive or remove the screw. Use controlled torque to avoid over-tightening; for fasteners requiring a specific torque, verify with a torque-measuring tool. The short 50 mm blade is intended for use where reach is limited—ensure the handle has sufficient clearance for comfortable rotation.

Usage recommendations

Inspect the tip before use for wear or damage and replace the tool if the square profile is rounded. For repetitive or high-torque applications, consider using a matching ratchet or powered tool with the correct square bit to reduce operator fatigue. Store the screwdriver in a dry place to prevent corrosion and maintain tip accuracy.
