Description

Phillips PH4 Screwdriver Bit, 8mm Hex Shank, 30mm Length

Brief Overview

This is a compact, purpose-built Phillips screwdriver bit designed for professionals who require reliable fastening in confined spaces or high-volume assembly operations. The 8mm hex shank provides universal compatibility with standard power tools and bit holders, while the 30mm stub length keeps the tool compact and rigid. If your shop works with multiple screw types, consider pairing this with Pozidriv-style bits or hex socket alternatives to cover a broader range of fastening applications.

Key Features

  • PH4 Cross Profile: Precise four-flute Phillips tip engineered to minimize cam-out and bit slippage on mid-sized fasteners
  • 8mm Hex Shank: Direct fit for 1/4" chuck power tools and standard bit holders; no adapter sleeve required
  • 30mm Stub Length: Compact design reduces flex and vibration during high-torque applications; ideal for tight-access assembly work
  • Machined Steel Construction: Grey metallic finish with sharp, clean flutes; triangular indexing marks for retention and easy identification
  • Chamfered Edges: Professional manufacturing detail that reduces stress concentration at transition points

Why This Bit Works for Your Business

Reseller Value: This is a high-turnover item. The PH4 size sits in the sweet spot of industrial fastening—large enough for production-grade work, small enough to move in volume. The stub length positions it as a specialist tool that justifies premium margin over standard bits.

Shop Reliability: The compact length and hex shank eliminate setup delays; mechanics simply load and drive without worrying about bit wobble or compatibility issues. Repeat orders are driven by bit wear, not replacement due to failure.

Bulk Order Efficiency: Stock depth in PH4 bits directly impacts your competitive position. A distributor holding 500-unit minimums can easily clear inventory through general maintenance and assembly shops.
