The Grey Pneumatic 5315S #5 Spline Drive 4-Point (Square) Impact Socket, 15/16 In, is engineered for professional technicians tackling stubborn square-head and spline fasteners in heavy-duty automotive, fleet, and industrial environments. This specialized impact socket delivers robust engagement and efficient power transfer, making it a reliable choice where standard hex sockets may struggle to provide adequate grip.

Key Features

• #5 Spline Drive Compatibility: Provides a secure fitment with #5 spline drive impact tools, maximizing power transfer and reducing cam-out under extreme loads.
• 4-Point Square Profile: Delivers solid engagement on square-head fasteners, gripping the flats to minimize rounding and slippage, crucial for older or seized components.
• Impact-Grade Chrome-Moly Steel: Manufactured from premium chrome-molybdenum alloy steel and heat-treated for superior strength and resistance to cracking under repeated impact use.
• High Torque Drive Geometry: Engineered to distribute stress away from the thinnest sections of the socket wall, enhancing strength and providing better protection for the fastener.
• Black Oxide Finish: A corrosion-resistant coating extends the tool’s service life in harsh shop, field, and industrial conditions.
• Permanent Size Markings: Features both laser-etched and roll-stamped size markings for quick and clear identification, even after extensive use.

Applications

This 15/16" impact socket is ideal for heavy-duty automotive, truck, agricultural, and industrial service where square or spline fasteners are common. It is frequently utilized on older vehicles for drivetrain and chassis hardware, and in heavy equipment and machinery maintenance where square-head plugs, set screws, or fittings are encountered. Intended for use with impact wrenches in demanding environments such as fleet garages, construction sites, and industrial plants.
