Klein Tools 610 Stubby Hollow Shaft Nut Driver Set 2 Piece

Product Description

The KLEIN TOOLS 610 is a 2-piece stubby nut driver set built for electrical and mechanical work in tight, restricted spaces where a standard-length driver cannot fit. The set includes one 1/4 inch and one 5/16 inch hollow shaft nut driver, each with a 1.5 inch shank and an overall length of 3.5 inches. The hollow shaft design allows the driver to seat over long bolts or threaded studs without bottoming out, which is a common limitation of solid-shaft drivers. Red and yellow cushion grip handles provide a comfortable, controlled grip and make it easy to grab the right size at a glance. This set is manufactured in the USA.

The 610 is intended for use by electricians, HVAC technicians, and other trade professionals who regularly work inside panels, junction boxes, equipment enclosures, or other confined areas where a full-length nut driver cannot generate the clearance needed. The stubby form factor keeps the tool close to the work surface, reducing the risk of slipping in cramped conditions. Both drivers are suited for residential and light commercial service work involving hex fasteners in the 1/4 inch and 5/16 inch range.

Key Features

• Stubby 3.5 inch overall length designed for work in close quarters and confined enclosures
• Full hollow shaft accommodates long bolts and threaded studs without obstruction
• 1.5 inch shank length keeps the tool compact while maintaining drive engagement
• Color-coded red and yellow cushion grip handles for quick size identification
• Includes both 1/4 inch and 5/16 inch sizes to cover the most common hex fastener sizes in trade work
• Made in USA

Compatibility

Designed for use with 1/4 inch and 5/16 inch hex fasteners. Suitable for general electrical, HVAC, and mechanical service applications requiring a compact hollow shaft nut driver.

Installation Notes

Always de-energize electrical equipment and verify absence of voltage before working inside panels or enclosures. Nut drivers should be used only on hex fasteners within the rated drive size to avoid fastener or tool damage. Inspect the cushion grip and shank for damage before each use. Work performed inside electrical enclosures should comply with applicable NFPA 70 requirements.
