Description

150mm Impact Torsion Bit, Phillips PZ2, S2 Tool Steel, Manganese Phosphate Finish

Brief Overview

This 150mm impact torsion bit is purpose-built for demanding fastening work in industrial settings where impact drivers deliver maximum rotational force. The extended length provides superior reach into recessed or hard-to-access screw pockets, while the dedicated torsion zone absorbs shock and protects the Phillips tip from cam-out and fracture. Built from S2 tool steel with a manganese phosphate finish, this bit combines durability with corrosion resistance—essential for high-volume production environments. Stock multiple lengths: pair this with shorter 50mm variants and comprehensive torsion bit sets for complete driver flexibility across your facility.

Key Features

  • 150mm total length – Extended reach for recessed fasteners, countersunk screw pockets, and assembly work in confined spaces
  • Phillips PZ2 tip – Compatible with standard cross-head screws; precise engagement reduces slippage and tip wear
  • Dedicated torsion section – Blue-marked flex zone absorbs rotational shock from impact drivers, preventing sudden breakage
  • S2 tool steel construction – High-strength alloy specifically engineered for repeated impact loading
  • Manganese phosphate finish – Corrosion-resistant dark coating extends tool life in humid or wet workshop environments
  • 1/4" hex shank – Quick-change compatible with all standard impact driver chucks and magnetic bit holders
  • Impact-rated design – Engineered for pneumatic and electric impact drivers; not suitable for manual screwdrivers

Business Advantages for Distributors

  • High-rotation durability – S2 steel with torsion zone dramatically reduces bit failure rates, improving customer retention and repeat orders
  • Extended inventory velocity – 150mm length fills a critical gap for specialty fastening applications (automotive assembly, industrial machinery, cabinetry)
  • Bulk-order friendly – Pair with shorter variants to create complete kits; resellers can bundle for premium pricing
  • Wear-resistant coating – Manganese phosphate finish maintains professional appearance longer, supporting premium positioning in your catalog
