Klein Tools s86m Magnetic Nut Driver 1/4 in 6 in Shank

Product Description

The KLEIN TOOLS s86m is a 1/4-inch magnetic nut driver built for electricians, HVAC technicians, and other trade professionals who need reliable fastener control in tight or overhead applications. A powerful nut-holding magnet is built directly into the shank, keeping fasteners seated during placement and removal. The chrome-plated, hollow shaft measures 6 inches in length, providing reach for deep fastener setups and allowing work on stacked circuit boards or applications involving long bolt protrusion. Internal flanges anchor the shaft solidly against the handle, resisting twist under load. Meets or exceeds applicable ASME and ANSI specifications.

This nut driver is suited for residential and commercial electrical panel work, HVAC control board service, and general trade applications where a 1/4-inch hex fastener is standard. The hollow shank design makes it practical for stacked circuit board assemblies and long-bolt applications where a solid-shank driver would bottom out. The color-coded handle allows quick identification in a pouch or tool bag alongside other sizes in the same driver family.

Key Features

• Built-in nut-holding magnet in shank keeps fasteners captured during install and removal
• Hollow shaft accommodates long bolt protrusion and stacked circuit board applications
• Chrome-plated shaft resists corrosion in field and shop environments
• Internal flanges provide a twist-resistant, solid connection between shaft and handle
• Color-coded Comfordome handle allows fast size identification in a tool bag
• Meets or exceeds ASME and ANSI specifications
• Made in the USA

Compatibility

Designed for use with standard 1/4-inch hex fasteners common in electrical panels, HVAC control boards, and general trade applications requiring a 6-inch shank nut driver.

Installation Notes

This tool is installed by hand and requires no special setup beyond confirming the correct drive size before use. When servicing electrical panels or control boards, always de-energize and lock out the circuit in accordance with NFPA 70E and applicable local codes before using any hand tool near live components. Inspect the chrome shaft and handle for cracks or damage before each use, and retire the tool if the shaft shows signs of deformation or the magnet has weakened significantly.
