#5 Spline Drive Heavy Duty 4-Point (Square) Impact Socket - 13/1 - Grey Pneumatic

The Grey Pneumatic 5313SHD #5 Spline Drive Heavy Duty 4-Point Impact Socket is engineered for professional technicians working with high-torque square fasteners in demanding fleet, heavy equipment, and industrial settings. Its robust chrome-molybdenum construction and compact profile ensure reliable engagement and superior access in challenging work areas where standard sockets may not fit or perform effectively.

Key Features

• #5 Spline Drive Connection: Facilitates a secure, positive lock-up with compatible spline drive impact extensions and drivers, ensuring efficient power transfer for high-torque applications.
• 13/16" 4-Point Square Opening: Precisely machined for optimal engagement with 13/16" square fasteners, significantly reducing the risk of slippage, rounding, and damage even under heavy loads.
• Chrome-Molybdenum Alloy Steel Construction: Heat-treated and specifically engineered for repeated impact use, this material offers exceptional resistance to cracking and deformation in demanding professional shop environments.
• Short Profile Design: Delivers a compact length, greatly enhancing access to square hardware in confined chassis, suspension, frame, and bracket locations, improving technician efficiency.
• Black Oxide Finish: Provides enhanced corrosion resistance and helps minimize surface wear, extending the tool's lifespan in harsh operational conditions.

Applications

This impact socket is an essential tool for servicing 13/16" square fasteners commonly found on heavy trucks, trailers, agricultural implements, and robust construction and industrial machinery. It is particularly valuable in fleet maintenance, municipal and utility services, and truck and trailer repair, especially where impact-rated square sockets are critical for secure fastening and removal. The short pattern is especially beneficial for accessing fasteners on tight crossmembers, suspension components, and equipment frames, making it ideal for mechanics working in cramped spaces.
