Description

Hex 8 Screwdriver Bit, 1/4-Inch Drive, 25mm Length

Brief Overview

This is a purpose-built hex 8 screwdriver bit engineered for professional assembly operations requiring precision engagement with hex-head fasteners. The compact 25mm overall length makes it ideal for confined spaces and tight assembly environments where standard bits won't fit. The machined steel construction delivers consistent performance across high-volume production runs. For applications requiring extended reach, we also stock longer hex bits in matching sizes, as well as smaller hex profile alternatives for fine-pitch fastener work.

Key Features

  • Hex 8 profile: Precisely machined external hexagon tip for direct engagement with hex-head fasteners
  • 1/4-inch hex drive shank: Direct compatibility with standard 1/4" hex power drills and manual screwdrivers
  • Compact 25mm length: Optimized for confined assembly spaces and tight work areas
  • Dark steel construction: Uniform finish, machined edges, and chamfered transitions for durability
  • Working length of 11mm: Controlled depth of bit engagement for consistent fastener seating

Why This Works for Your Shop

  • Stock depth efficiency: The 25mm compact length reduces inventory footprint while covering high-frequency assembly tasks
  • Margin-friendly: Hex bits are high-turnover items with consistent customer demand
  • Assembly-line reliable: No cam-out risk with properly matched hex fasteners; reduces rework and scrap
  • Bulk-order scalable: Pair with complementary sizes to create complete hex bit kits for resale
