Impact PH2 screwdriver bit 90 mm S2 Tvardy (pack quantities vary)

Impact PH2 screwdriver bit 90 mm S2 Tvardy is a single-piece Phillips PH2 driver tip manufactured from S2 tool steel and sized for a 90 mm working length. It is intended for use with impact drivers and impact-capable screwdrivers where sustained torque and repeated fastening cycles are required. The S2 steel composition and impact-rated design support higher torque transfer and improved resistance to wear compared with standard bits of similar size.

Advantages

The bit's S2 tool steel construction offers increased hardness and toughness for longer service life under impact conditions. At 90 mm length the bit provides extended reach into recessed screw locations while maintaining stability in the chuck. Its geometry is optimized for Phillips PH2 fasteners to reduce cam-out and improve engagement, and the impact-rated design reduces deformation during high-torque applications.

Suitable for

• Assembly of furniture and fittings using Phillips PH2 screws
• General construction tasks where impact drivers are used
• Repair and maintenance work that requires durable PH2 fastening
• Electrical and HVAC installations with recessed or hard-to-reach screws

Key specifications

• Tip type: Phillips PH2
• Material: S2 tool steel
• Overall working length: 90 mm
• Design: impact-rated for use with impact drivers
• Finish: industrial grade surface treatment for wear resistance

How to use

Insert the 90 mm PH2 bit securely into the driver or impact adapter according to the tool manufacturer's instructions. Position the bit squarely into the PH2 screw head, apply steady axial pressure and operate the impact driver at an appropriate torque setting for the screw and material. Periodically inspect the tip for rounding or wear and replace the bit when engagement quality decreases to maintain fastening accuracy.

Usage recommendations

Use this S2 impact bit specifically with impact-rated drivers or adapters. Match torque settings to screw size and substrate to avoid overdriving. Store bits in a dry holder to prevent corrosion and replace damaged bits to ensure secure fastening and to prevent screw or workpiece damage.
