Klein Tools Magnetic Pass Through Multi Nut Driver 32809MAG 5 Piece 9 in 1 SAE (Alloy Steel Wrench Assist Cushion Grip Fastening Set)

Klein Tools 32809MAG 9-in-1 Magnetic Pass-Through SAE Multi-Nut Driver Set

The Klein Tools 32809MAG 9-in-1 Pass-Through SAE Multi-Nut Driver consolidates nine essential imperial hex socket sizes into a versatile five-piece manual fastening tool designed for continuous threaded rod applications. Constructed from high-strength forged alloy steel, this 12 oz (0.75 lb) uninsulated multi-driver features hollow pass-through barrels and a Cushion-Grip handle that allow long threaded studs and all-thread rod to pass entirely through the tool body without bottoming out. Integrating powerful Rare-Earth magnets on smaller socket drives (1/4", 5/16", 11/32", 7/16") alongside internal retention spring coils on larger sizes (3/8", 1/2", 9/16", 3/4"), this heavy-duty system enables electrical contractors, HVAC installers, and mechanical tradespeople to execute one-handed nut running on overhead strut channels and trapeze hangers.

Best Used For:

• Overhead Threaded Rod & Trapeze Hanger Installation: Fastening hex nuts onto long all-thread rods without hitting internal tool depth limits.
• Electrical Strut & Conduit Support Mounting: Securing 3/16-inch through 3/4-inch SAE hex nuts on Unistrut channels, junction box mounts, and cable trays.
• High-Torque Maintenance & Seized Fastener Removal: Applying external open-end or adjustable wrench leverage to the integrated barrel bolster for increased breaking torque.

Key Performance & Safety Features

• 9-in-1 Multi-Nut Capacity: Houses 3/16", 1/4", 5/16", 11/32", 3/8", 7/16", 1/2", 9/16", and 3/4" SAE hex sockets within one compact handle assembly.
• Full Pass-Through Shaft Architecture: Hollow shaft and barrel design allows long studs and threaded rods of any length to pass completely through the driver.
• Dual Fastener Retention System: Uses Rare-Earth magnets for 1/4", 5/16", 11/32", and 7/16" sizes, and heavy-duty spring coils for 3/8", 1/2", 9/16", and 3/4" sizes to ensure slip-free holding.
• Extended Wrench-Assist Bolster: Built-in hex bolster on driver barrels allows wrench engagement for extra mechanical leverage on stubborn fasteners.
• Ergonomic Cushion-Grip Handle: CA/TPE dual-material handle provides superior rotational torque and reduced hand fatigue during repetitive driving.
• Color-Coded Size Identification: Distinct color bands enable instant visual identification of target socket sizes in low-light work zones.

What's Included

• (1) Klein Tools Cushion-Grip Pass-Through Handle
• (4) Interlocking Pass-Through Alloy Steel Nut Driver Barrels (3/16" through 3/4" SAE)

Technical Specifications

Pro-Tip: When running hex nuts down long, rusted all-thread rods, slide an open-end wrench onto the barrel's wrench-assist bolster. This gives you high mechanical advantage to break through corroded threads without damaging the driver handle or slipping off the nut.
