Sk 46155 Impact Locking Socket Extension 31 in

Product Description

The SK 46155 is a 1/2 inch drive impact locking socket extension built for high-torque applications in professional shop and field environments. At 31 inches overall length, it bridges the gap between impact wrenches and hard-to-reach fasteners — particularly useful in automotive, heavy equipment, and industrial maintenance work. The locking mechanism retains the socket under load and vibration, reducing dropped sockets in confined spaces. A black oxide finish provides corrosion resistance for tool storage environments. Weighing 2.5 pounds, this is a solid-steel extension sized for demanding service use.

This extension is suited for mechanics, fleet technicians, and industrial maintenance professionals who need extended reach without losing socket retention during impact driving. The 31 inch length is particularly applicable when working in engine bays, undercarriage access, or equipment panels where standard-length extensions fall short. It is compatible with standard 1/2 inch drive impact sockets and impact wrenches. The locking feature is especially valuable in overhead or inverted installations where socket dropout is a safety concern.

Key Features

• 31 inch overall length provides extended reach for deep or obstructed fastener access
• 1/2 inch drive fits standard impact wrenches and impact sockets
• Locking mechanism retains socket under vibration and high-torque impact use
• Black oxide finish resists corrosion during storage and regular shop use
• Backed by a Limited Lifetime Warranty

Compatibility

Designed for use with standard 1/2 inch drive impact sockets and impact wrenches. Verify drive size compatibility before installation.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians. Ensure the impact wrench is powered down and the air supply or battery is disconnected before attaching or removing the extension. Confirm the locking collar is fully engaged before applying torque. Do not use this extension with hand ratchets or non-impact drivers where the locking retention feature may interfere with standard socket release.
