Description

8mm Tamper-Resistant Torx Bit, H50 Profile, 30mm Length, 1/4-Inch Hex Drive

Brief Overview

This tamper-resistant Torx bit is engineered for applications requiring security-level fastening where unauthorized removal must be prevented. The H50 profile with central pin recess ensures positive engagement and resists cam-out during high-torque operations. The 30mm length and 1/4-inch hex drive make it compatible with standard impact drivers and pneumatic tools, while the matte-finished steel construction delivers durability for demanding production environments. Stock this alongside other tamper-resistant security bits to serve shops handling restricted-access assemblies and security-sensitive components.

Key Features

  • Tamper-Resistant Design: Central pin recess prevents unauthorized removal and requires specialized driver compatibility
  • Six-Lobed Torx Profile (H50): Maximizes contact area to reduce cam-out and distributes load evenly across fastener head
  • 1/4-Inch Hex Drive: Fits all standard 1/4-inch impact driver holders and pneumatic tool chucks
  • Optimized Length: 30mm overall length balances reach and rigidity for precision assembly work
  • Precision-Machined Steel: Shot-peened matte finish resists corrosion and provides consistent surface grip
  • Shallow Fluting: Reduces stress concentration while maintaining structural integrity under cyclic loading

Business Advantages for Resellers

  • High Margin Product: Security-grade bits command premium pricing over standard Torx equivalents
  • Niche Market Demand: Growing adoption in aerospace, automotive security systems, and restricted-access assembly
  • Bulk-Friendly: OEM-grade specification allows competitive wholesale pricing for high-volume orders
  • Compatibility: Works with existing 1/4-inch driver infrastructure—no additional tool investment required for your customers
  • Differentiation: Position your shop as a one-stop source for both standard and security fastening solutions
