Screwdriver bit Proline 58511, single bit, length 100 mm

Proline 58511 is a single screwdriver bit with a 100 mm length designed as a replaceable bit for manual or powered screwdrivers. It provides a direct interface between driver and fastener, offering consistent engagement and predictable torque transfer where a longer reach or deeper access is required. Supplied as a single piece, the bit fits standard bit holders and quick-change chucks used in common assembly, repair and maintenance operations.

Advantages

The 100 mm length gives improved access to recessed fasteners and components in confined spaces while maintaining stable seating in the driver. Made to a standard geometry, the bit offers repeatable fit and alignment with compatible screw heads. Supplied individually, it is convenient for replacing worn bits or stocking a specific length for specialist tasks.

Suitable for

• Assembly tasks requiring extended reach to fasteners recessed in housings or panels
• Repair and maintenance where standard-length bits cannot access the screw
• Use with manual handles or powered drivers equipped with standard bit holders
• Situations needing a single, dedicated bit length for repeatable operations

Key specifications

• Type: single replaceable screwdriver bit
• Length: 100 mm
• Compatibility: fits standard bit holders and quick-change chucks
• Usage: manual and powered screwdriver applications

How to use

Insert the Proline 100 mm bit into a compatible bit holder or quick-change chuck until it seats securely. Select the appropriate driver and engage the bit with the fastener, applying steady axial pressure to maintain engagement. For powered drivers, use controlled speed and torque settings suitable for the fastener and material to avoid cam-out or damage. When finished, withdraw the bit from the holder and store or replace as required.

Usage recommendations

Use the bit with drivers and holders rated for the intended torque. Avoid applying excessive side load or bending force on the 100 mm shaft to prevent deformation. Inspect tip condition regularly and replace the bit when wear or rounding of the tip is observed to ensure consistent fastening performance.
