Screw bit set Proline T27 x 75 mm, 10 mm shank, 2 pieces

Set of two Proline T27 screw bits, each 75 mm long with a 10 mm shank. Manufactured from high-quality S2 alloy tool steel with hardness HRC 56–60, the bits have a fine-grained homogeneous structure that provides torsion resistance and reliable torque transmission for Torx T27 fasteners. The compact 2-piece set is suitable for use with compatible screwdrivers and bit holders for assembly, repair and maintenance tasks where reach and consistent fit are required.

Advantages

Made from S2 alloy tool steel with HRC 56–60 hardness for durability and wear resistance. Fine-grained homogeneous material ensures good torsional strength and prevents premature breakage. 10 mm shank fits common bit holders and quick-change chucks. The 75 mm length provides extra reach for recessed or hard-to-access Torx T27 fasteners while maintaining stable torque transfer of up to the specified capability.

Suitable for

• Assembly of furniture and fixtures using Torx T27 fasteners
• General repair and maintenance tasks requiring extended reach
• Use with 10 mm bit holders, magnetic bit holders and compatible screwdrivers

How to use

Insert the 10 mm shank into a compatible bit holder, quick-change chuck or screwdriver. Position the Torx T27 tip into the fastener head and apply steady axial pressure while turning the driver at an appropriate speed and torque setting. For best engagement, ensure the bit is fully seated in the screw head before applying high torque. After use, store the bits in a protective case or tool organizer to prevent damage and corrosion.

Usage recommendations

Use appropriate personal protective equipment and select torque settings within the capacity of the bit and the fastener. Avoid excessive side load or impact that can cause premature wear or breakage; replace bits that show rounding or damage to the tip.
