Klein Tools Slotted Impact Socket 66031 3 in 1 SAE 12 Point (1/2 Square Drive 4140 Steel Hot Line Clamp Pole Hardware Tool)

Klein Tools 66031 3-in-1 Slotted Reversible 12-Point SAE Impact Socket

The Klein Tools 66031 3-in-1 Slotted Impact Socket combines 3/4-inch and 9/16-inch hex openings into a single high-torque driving attachment engineered for electrical utility pole hardware installation and maintenance. Forged from heat-treated 4140 alloy steel, this ultra-lightweight 0.8 oz (0.05 lb) ASME B107.2 compliant socket mounts directly onto standard 1/2-inch square drive power impact drivers and wrenches. Featuring an integrated side alignment slot specifically designed to engage curved hot-line clamp eyebolts, J-hooks, and pole steps, this hands-free dual-ended tool allows power line technicians and electrical contractors to transition between hardware sizes without detaching the socket or taking off protective work gloves aloft.

Best Used For:

• Hot-Line Clamp & Utility Pole Hardware Fastening: Tightening and loosening hot-line clamp loops, J-hooks, pole steps, and eyebolts utilizing the integrated side clearance slot.
• Dual-Size Square & Hex Bolt Driving: Securing 3/4-inch and 9/16-inch hex bolts or 4-point square utility nuts using high-torque 12-point socket geometry.
• Overhead High-Torque Power Tool Operation: Driving pole line hardware directly on 1/2-inch square impact wrenches during aerial distribution line repairs.

Key Performance & Safety Features

• 3-in-1 Reversible Slotted Design: Combines 3/4-inch hex, 9/16-inch hex, and an integrated hot-line clamp alignment slot within a single socket body.
• Hands-Free Size Adjustment: Inner spring mechanism compresses smoothly to allow instant transitions between fastener sizes without stopping work.
• High-Torque 12-Point Socket Geometry: Delivers flexible multi-angle positioning for fast seating over square nuts and standard hex fasteners.
• Forged 4140 Steel Construction: Premium heat-treated alloy steel meets ASME B107.2 standards to handle continuous rotational impact shocks.
• Transverse Cross-Hole Safety Retention: Cross-hole alignment keeps the socket securely locked onto impact tool drive anvils under severe vibration.
• Double-Line Color-Coded Identification: High-visibility painted double rings provide fast visual size and slotted feature identification in dark environments.

What's Included

• (1) Klein Tools 66031 3-in-1 Slotted 12-Point Impact Socket (3/4" x 9/16")

Technical Specifications

Pro-Tip: When installing hot-line clamps or curved eyebolts overhead, position the side alignment slot directly over the wire loop before applying power. The slot bypasses extended hardware loops so the 12-point socket seats completely over the base nut without binding.
