GY-HS Sockets Heavy Duty 1/4″ (6.35mm) Square Drive

Our premium line of 1/4″ Square Drive Industrial Sockets is engineered for precision, durability, and versatility. Designed specifically for hand-operated tasks, these sockets feature a double hex (12-point) configuration, allowing for easier engagement with fasteners in tight spaces and a reduced swing arc.

Constructed for professional-grade use, these tools are available in both Metric and American (SAE) sizes to ensure a perfect fit for any international project

Key Features

  • Drive Size: 1/4″ Square Drive, compatible with standard industrial impact wrenches and ratchets.
  • Profile: Double Hex (12-point) design, allowing for easier engagement with fasteners and better performance in tight spaces.
  • Precision Engineering: Detailed specifications provided for Socket End Diameter, Drive End Diameter, Broach Depth, and Bolt Clearance to ensure exact fitment for industrial maintenance.
  • Secure Attachment: Designed for use with driving tools featuring spring-loaded ball and button locking mechanisms for maximum safety during use.
  • Finish: Industrial black phosphate finish for superior corrosion resistance and durability in high-torque environments.
Product Options
We offer two distinct profiles to meet your specific mechanical needs:
