Grey Pneumatic 81659crd 3/8 in Drive 59-pc Socket Set

Product Description

The GREY PNEUMATIC 81659crd is a 59-piece, 3/8 inch drive duo-socket set covering both SAE fractional and metric sizes in standard and deep lengths, all built to 6-point high-torque geometry. The high-torque drive profile contacts fastener flats rather than corners, reducing wear on both the fastener and the socket wall while transferring greater torque and allowing access in confined spaces. Sockets are constructed from chrome-molybdenum alloy steel for impact-rated durability. The set ships in a molded carrying case. It is intended for professional technicians and tradespeople who rely on impact tools in production or field environments.

This set is suited for automotive, industrial, assembly, mining, maintenance, construction, and energy applications. The combination of fractional and metric coverage in a single case makes it practical for shops that work across both measurement standards without carrying two separate socket sets. Standard-length sockets handle open-access fasteners; deep-length sockets reach recessed or stud-mounted hardware. The included 72-tooth quick-release ratchet, 3 inch extension, and 6 inch extension give technicians the drive accessories needed for most common 3/8 inch drive tasks without sourcing additional components.

Key Features

• High-torque 6-point drive geometry reduces fastener and socket corner wear
• Chrome-molybdenum alloy steel construction rated for impact tool use
• Dual coverage: 12 SAE fractional sizes (5/16 inch through 1 inch) in both standard and deep lengths
• Dual coverage: 16 metric sizes (7 mm through 22 mm) in both standard and deep lengths
• Includes 8 inch, 72-tooth quick-release ratchet plus 3 inch and 6 inch extensions
• Organized molded case keeps all 59 pieces sorted and portable

Compatibility

Designed for use with standard 3/8 inch drive impact tools and hand ratchets across automotive, industrial, assembly, mining, maintenance, construction, and energy industry applications.

Installation Notes

Install and remove this set using a qualified mechanic or industrial technician following applicable workplace safety procedures. Verify the drive tool torque rating is appropriate for the fastener specification before applying power. Inspect each socket for cracks or deformation before use and remove any damaged socket from service immediately. Do not use impact sockets on hand-torque tools where a precision torque value is required unless the fastener specification permits it.
