Screwdriver bit Proline 510833 10 mm hex shank, 5×75 mm tip, set of 2

Set of two Proline screwdriver bits with a 10 mm hex shank and 5×75 mm tip size. The bits are made from high-quality S2 alloy tool steel with a hardness of HRC 56–60, providing a homogeneous fine-grain structure and torsional strength for reliable fastening performance. These 5 mm tips with 75 mm length fit standard hex chucks and are intended for use with compatible bit holders, power drivers, and manual screwdrivers.

Advantages

Bits manufactured from S2 alloy steel deliver high hardness and wear resistance (HRC 56–60), uniform microstructure and improved torsional resistance. The 10 mm hex shank offers a secure fit in hex holders and quick-change chucks, while the 75 mm length provides extended reach for recessed or hard-to-access fasteners. Supplied as a set of two for replacement or parallel use.

Suitable for

• General fastening and assembly tasks

How to use

Insert the 10 mm hex shank into a compatible bit holder, quick-change chuck or screwdriver with a 10 mm hex socket. Ensure the bit is fully seated and locked before applying torque. Use an appropriate driver speed and torque setting for the fastener and material to avoid bit damage. Replace bits when wear degrades fit or driving performance.

Usage recommendations

For best results, match the 5 mm tip to the correct fastener profile and avoid excessive side load. When using with power drivers, start at low speed to ensure correct engagement, then increase speed as needed. Store bits in a dry place to prevent corrosion and inspect regularly for wear.
