Product Description

Brief Overview

This 8mm hex impact socket is engineered for high-torque pneumatic impact applications where standard sockets fall short. The 78mm extra-long design reaches fasteners in recessed or deeply-positioned locations—a critical requirement in engine work, suspension assembly, and industrial machinery maintenance. For shops requiring a complete impact hex socket system, complement this tool with larger capacity impact hex sockets or dedicated small-hex deep sockets to cover the full fastener spectrum.

Key Features

  • Impact-Rated Construction: Designed to withstand the shock loads of pneumatic impact wrenches without fracturing or deforming
  • Extra-Long 78mm Design: Reaches fasteners in deep or recessed cavities where standard sockets cannot access
  • 8mm Hex Bit: Precise fit for M8 and equivalent 8mm hex socket cap screws
  • 1/2-Inch Square Drive: Compatible with all 1/2" drive impact wrench adapters and extensions
  • Matte Black Finish: Hard-anodized surface resists corrosion and wear in demanding workshop environments
  • Metric Specification: Calibrated to metric standards for OEM and industrial applications

Business Advantages for Resellers

Bulk Order Opportunity: Impact hex sockets represent a high-margin, consumable category in professional shops. Mechanics and technicians frequently replace worn or damaged impact sockets, creating recurring demand. Stock this 8mm variant as part of a complete impact socket range to capture multiple sale cycles per year.

Competitive Positioning: Deep impact hex sockets are less common than standard hex sockets, giving you a differentiation point with shops that handle complex engine and suspension work. Position this as part of a "specialty impact set" to increase average order value.

Tool Replacement Cycle: Impact sockets experience gradual wear and occasional failure under extreme torque. A 78mm extra-long 8mm hex socket will see heavy use in any professional shop, ensuring steady reorder potential.
