Klein Tools 32809MAG 9-in-1 Sae Magnetic Nut Driver

Product Description

The KLEIN TOOLS 32809MAG is a 9-in-1 pass-through SAE magnetic multi-nut driver built for electricians, plumbers, and HVAC technicians who need to drive hex nuts onto threaded rod of any length. The pass-through handle and barrel design eliminates the depth restriction common to standard nut drivers, letting the fastener pass completely through the tool. Nine SAE socket sizes are integrated into a single tool: 3/16, 1/4, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, and 3/4 inch. Rare-earth magnets secure smaller sizes for one-handed driving, while a spring coil retains larger sizes where magnets are not used.

This tool is suited to residential and commercial trade work where hex nuts on all-thread rod, strut, and conduit supports are common fastening tasks. Electrical installers securing conduit straps, HVAC techs fastening equipment supports, and plumbers working with threaded rod hangers all benefit from the pass-through design. The extended wrench-assist flats on the barrels allow a wrench or pliers to add torque when hand driving is not enough for a tight or seized fastener. Color-coded bands on each barrel allow the tech to identify the correct size quickly without reading stamped markings in low-light conditions.

Key Features

• Nine SAE sizes in one tool: 3/16, 1/4, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, and 3/4 inch
• Pass-through handle and barrels allow fastening onto threaded rod of any length
• Rare-earth magnets hold nuts for one-handed driving on 1/4, 5/16, 11/32, and 7/16 inch sizes
• Spring coil retention on 3/8, 1/2, 9/16, and 3/4 inch sizes where magnets are not used
• Extended wrench-assist flats on barrels for added torque with a wrench or pliers
• Color-coded bands for fast size identification in the field
• Cushion-Grip handle provides comfort and increased hand torque

Compatibility

Designed for use with standard SAE hex nuts and bolts on threaded rod, all-thread, and conventional fasteners in electrical, HVAC, and plumbing applications.

Installation Notes

This tool is intended for hand-tool use by licensed trades including electricians, HVAC technicians, and plumbers. When using the wrench-assist flats to add torque with a wrench or pliers, apply force steadily to avoid slipping off the fastener. As with any multi-barrel nut driver, confirm the correct barrel is selected and fully seated on the fastener before applying torque. No power tools should be used with this manual driver.
