Klein Tools 646-11/32 Nut Driver Sae 6 Inch Shank

Product Description

The KLEIN TOOLS 646-11/32 is a hollow round shank nut driver built for professional tradespeople who need a reliable, fixed-socket hand tool for driving hex nuts and bolts. The straight shank design features a single fixed socket at the tip in SAE sizing, without a magnetized tip. With a 6-inch shank length, this driver provides extended reach into recessed or tight fastener locations commonly encountered in electrical panels, HVAC equipment, and control assemblies. Licensed electricians, HVAC technicians, and plumbers will find this a practical everyday driver for standard fastening tasks.

This nut driver is suited for residential and light commercial service work where SAE hex fasteners are standard. The 6-inch shank length gives additional reach inside enclosures, junction boxes, and equipment cabinets without requiring extensions. Its hollow shank design also allows it to pass over threaded rod or long bolt shanks, which adds flexibility in tight installation scenarios.

Key Features

• Hollow round shank allows use over threaded rod and long bolts
• 6-inch shank length provides extended reach into recessed fastener locations
• Fixed SAE socket tip for consistent, single-size fastening
• Straight shank orientation for direct torque transfer
• Non-magnetized tip suits applications where magnetic attraction is undesirable

Compatibility

Designed as a standard SAE nut driver suitable for driving hex nuts and bolts in electrical, HVAC, and plumbing service applications where a 6-inch straight shank is appropriate.

Installation Notes

This tool is used by electricians, HVAC technicians, and plumbers for hand-tightening or loosening hex fasteners during equipment service. Always de-energize electrical equipment and follow applicable NEC guidelines before working inside panels or control enclosures. Inspect the socket tip and shank for wear or damage before each use. Do not use nut drivers as pry bars or apply side-loading force to the shank.
