Klein Tools Ratchet Socket Adapter Set 65408ADP 2 Piece 3/8 Inch Drive Pass Through KNECT M (90 Tooth Alloy Steel Threaded Rod Fastening)

Klein Tools 65408ADP KNECT™ (M) Pass-Through Ratchet and 3/8-Inch Socket Adapter Set

The Klein Tools 65408ADP KNECT™ (M) Pass-Through Ratchet and 3/8-Inch Socket Adapter Set is an interchangeable hand-driving system engineered with a 90-tooth ratcheting mechanism to deliver precise arc swings in confined spaces. Forged from heat-treated Chrome-Molybdenum and Chrome-Vanadium alloy steel with a black manganese phosphate finish, this two-piece kit measures 8.38 inches long and features a slim 1.09-inch wide head profile for navigating tight clearances. Designed for commercial electricians and mechanical technicians, the hollow pass-through wrench easily runs hex nuts down extended threaded rods, while the included 3/8-inch adapter integrates standard square drive sockets for versatile, high-torque jobsite fastening.

Best Used For:

• Deep Threaded Rod Fastening: Running hex nuts continuously down extended 3/8-inch threaded rods for suspended electrical conduit and HVAC trapeze hangers without deep socket depth limitations.
• Low-Clearance Hardware Installation: Accessing and driving fasteners inside shallow junction boxes or crowded utility bays utilizing the slim 1.31-inch high profile ratchet head.
• Standard Socket System Integration: Converting the specialized pass-through ratchet handle to operate traditional 3/8-inch square drive impact sockets for standard mechanical bolting.

Key Performance & Safety Features

• 90-Tooth Pass-Through Head: Hollow gear design allows threaded rods to pass completely through the wrench while providing a minimal 4-degree swing arc for tight spaces.
• 3/8-Inch Square Drive Adapter: Included converter locks securely into the KNECT™ M interface to run standard 3/8-inch square drive sockets.
• Directional Selector Switch: Clearly labeled reversing lever enables rapid one-handed switching between clockwise ratcheting and counterclockwise loosening.
• Cr-Mo and Cr-V Steel Forging: High-tensile alloy construction withstands heavy manual torque applications without flexing or stripping internal gears.
• Black Manganese Phosphate Coating: Industrial surface treatment delivers advanced corrosion and rust resistance in harsh or damp environments.
• Ergonomic Contoured Handle: Molded steel grip geometry reduces operator hand fatigue during continuous overhead threaded rod installations.

What's Included

• (1) Klein Tools KNECT™ (M) Pass-Through Ratcheting Wrench Handle
• (1) KNECT™ (M) Interface to 3/8-Inch Male Square Drive Socket Adapter

Technical Specifications

Pro-Tip: When installing unistrut trapeze hangers overhead, slide the hex nut onto the threaded rod first, then slide the pass-through ratchet directly over the rod. This eliminates the depth limitations of traditional deep sockets and allows for continuous ratcheting until the strut hardware is fully seated against the mount.
