#5 Spline Drive 4 Pt (Square) Impact Socket - 15/16" - Grey Pneumatic

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

Key Features

• #5 Spline Drive Compatibility: Engineered for a secure fitment with #5 spline drive impact tools, this design maximizes power transfer and reduces the risk of cam-out under extreme loads.
• 4-Point Square Profile: Provides solid engagement on square-head fasteners, gripping the flats to minimize rounding and slippage, which is crucial for maintaining integrity on older or seized hardware.
• Impact-Grade Chrome-Moly Steel: Manufactured from premium chrome-molybdenum alloy steel and heat-treated, ensuring superior strength and resistance to cracking or fracturing under repeated impact use.
• High Torque Drive Geometry: Designed to distribute stress away from the thinnest sections of the socket wall, enhancing overall strength and offering improved protection for both the socket and the fastener.
• Black Oxide Finish: A corrosion-resistant coating extends the tool’s service life, making it suitable for 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 and exposure to grime.

Applications

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