Screwdriver bits Proline 5108388, 10 mm, set of 2

Set of two Proline 3/8" hex screwdriver bits, size 10 x 75 mm (model 5108388). The bits are made from high-quality S2 alloy tool steel with high hardness (HRC 56–60), offering a fine-grained, homogeneous material structure and improved torsional resistance. The pair is supplied in compact packaging for convenient storage and transport and is suitable as spare or replacement bits for manual and compatible power tool use.

Advantages

Bits manufactured from S2 alloy tool steel provide high wear resistance and durability while maintaining a consistent geometry. High hardness (HRC 56–60) and fine-grained structure increase torsional strength and allow transfer of a tightening torque up to 21.8 Nm. The compact two-piece set is convenient for carrying and on-site tasks.
