GY-IS Impact Sockets 1.1/2″ (38.10mm) Square Drive

Engineered for the high-torque demands of impact wrenches, the 1.1/2″ Square Drive Impact Socket Series provides the ultimate combination of strength and precision. Designed for professional mechanics and industrial technicians, these sockets are built to withstand heavy-duty loads without compromising on fit.

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: 1.1/2″ Square Drive, Designed for use with high-output pneumatic or hydraulic impact wrenches.
  • Single Hex (6-Point) Design: Provides a secure, flat-to-flat grip on fasteners, significantly reducing the risk of rounding corners during high-torque operations.
  • Precision Engineering: Detailed specifications provided for Socket End Diameter, Drive End Diameter, Broach Depth, and Bolt Clearance to ensure exact fitment for industrial maintenance.
  • Heavy-Duty Construction: Manufactured from high-grade alloy steel and heat-treated for superior strength to withstand extreme impact forces.
  • Secure Retaining System: Integrated cross-hole retaining design ensures the socket stays securely locked onto your impact tool.
  • Finish: Industrial black phosphate finish for superior corrosion resistance and durability in high-torque environments.
  • Safety Note: Always ensure the socket is securely locked to the drive square using the appropriate retaining pin and ring before operation.
Product Options
We offer two distinct profiles to meet your specific mechanical needs:
1. Standard Impact Sockets
Ideal for general assembly and maintenance where space is not a constraint.
  • Metric Sizes: Available from 36mm to 120mm (Table A).
  • American (SAE) Sizes: Available from 1.3/8″ to 4.5/8″ (Table C).
  • Overall Length (OAL): Standardized lengths for predictable tool handling of 76mm-145mm.
2. Deep Impact Sockets
Engineered to accommodate long studs and recessed fasteners that standard sockets cannot reach.
  • Metric Sizes: Available from 36mm to 120mm (Table B).
  • American (SAE) Sizes: Available from 1.3/8″ to 4.5/8″ (Table D).
  • Overall Length (OAL): Standardized lengths for predictable tool handling of 140mm-170mm.
