#5 Spline X 15" Extension With Lock Button GP5515E

Grey Pneumatic professional-grade #5 spline drive 15-inch impact extension designed for high-torque industrial and commercial truck applications. It features an integrated lock button socket retention system that provides a secure, positive connection to prevent heavy spline sockets from accidentally detaching during operation. Forged from high-strength chrome-molybdenum alloy steel, this extension is engineered to handle the extreme power of spline-drive impact tools while providing the necessary reach for deep or obstructed fasteners.
Key Features
Lock Button Retention: Features a mechanical lock button that securely holds the socket in place, offering superior safety and reliability compared to standard friction ball retainers.
#5 Spline Drive System: Specifically designed for use with #5 spline drive impact wrenches and sockets, providing multiple contact points for maximum torque transfer and reduced vibration.
GP High Torque Drive: Innovative design transfers pressure away from the thinnest part of the tool toward the thicker sections, increasing overall strength and durability.
Industrial Construction: Manufactured from premium heat-treated chrome-molybdenum steel for an optimal balance of strength and impact resistance.
Corrosion Resistance: Finished with a protective black oxide coating to resist rust and wear in harsh shop or industrial environments.
Extended Reach: The 15-inch length provides critical access to deeply recessed fasteners in truck wheels, hubs, and heavy equipment assemblies.
