5/16\" x 3/8\" S-Style Double Box End Wrench - Sunex Tools

The Sunex Tools 994001 5/16" x 3/8" S-Style Double Box End Wrench is engineered for professional technicians and mechanics who require reliable access in challenging workspaces. Its unique S-curve design allows for maximum reach around obstructions, making it an essential tool for difficult-to-access fasteners in automotive and industrial applications. This professional-grade wrench delivers both durability and precision, ensuring efficient operation in demanding environments.

Key Features

• S-Style Design: The distinctive S-shape provides superior access to fasteners located in confined and obstructed areas where traditional straight wrenches cannot reach.
• Double Box End: Features two different 12-point box ends (5/16" and 3/8") for versatile application on a range of fastener sizes, ensuring a secure grip and minimizing the risk of rounding.
• Durable Construction: Manufactured from drop-forged alloy steel, specifically chrome vanadium or chrome-molybdenum steel, for exceptional strength, resilience, and a long service life.
• Fully Polished Finish: The polished surface not only enhances corrosion resistance but also allows for easy cleaning after rigorous use.
• 12-Point Design with Radius Corners: The 12-point configuration provides more contact points for better grip and allows for smaller swing arcs in tight spaces. Radius corners grip the flat sides of fasteners, not the corners, to prevent round-off.
• Easy Identification: Sizes are clearly stamped on both sides of the wrench for quick and convenient identification.

Applications

It is particularly effective for reaching fasteners on components such as starters, alternators, power steering pumps, water pumps, and automotive door hinges, where obstructions make conventional wrenches impractical.
