Klein Tools 610-5/16 Stubby Nut Driver 5/16 Inches

Product Description

The KLEIN TOOLS 610-5/16 is a stubby nut driver designed for fastening and loosening hex nuts in tight spaces where a standard-length driver will not fit. The stubby form factor shortens the overall reach while maintaining the hex tip engagement needed for reliable torque transfer. This type of hand tool is a staple in the pouches of electricians, HVAC technicians, and plumbers who work inside panels, junction boxes, and equipment cabinets on a regular basis. The 5/16-inch drive size is one of the most common hex nut sizes found in electrical and mechanical trade work.

This nut driver is suited for residential and light commercial service work where compact access is a recurring challenge. Common applications include working inside breaker panels, HVAC air handler cabinets, motor junction boxes, and equipment access covers where standard nut drivers are too long to swing freely. It is sold individually and is well-suited as a targeted addition to an existing driver set.

Installation Notes

This tool is used by electricians, HVAC technicians, and plumbers for hand-tightening and loosening hex nuts. Always de-energize electrical panels and equipment before working inside enclosures, in accordance with NFPA 70E lockout/tagout procedures. No power source is required for operation. Inspect the hex tip for wear before use to ensure proper nut engagement.
