Grey Pneumatic 1164QL Drive Impact Locking Extension - 3/8 24

The Grey Pneumatic 1164QL is a 24-inch impact locking extension with a 3/8-inch drive, designed for secure socket retention and maximum durability in high-torque applications. This professional-grade extension features a unique quick-lock mechanism that prevents accidental socket disengagement during use.

Key Features:

• Quick-lock design securely locks sockets to the extension and will not disengage until the knurled sleeve is pulled back
• Pin on the square drive provides maximum security against accidental socket release
• Constructed from premium chrome-molybdenum steel for superior strength
• Heat treated for enhanced durability and resistance to wear
• Hard-stamped size markings for easy identification that won't wear off
• 24-inch length provides extended reach for deep or hard-to-access fasteners

Grey Pneumatic's impact sockets grip fasteners across a broader contact area, reducing the risk of rounding off bolt heads and allowing up to 20% more torque application compared to conventional impact sockets. The optimized pressure distribution enables reduced socket wall thickness, providing better access in tight spaces while maintaining exceptional strength.
