Sunex Tools 228XD Extra Deep Socket - 1/2 in Drive, 7/8 in, 6-Point, CR-MO Steel

Overview

The Sunex Tools 228XD introduces a premium extra-deep socket designed to reach fasteners hidden behind long bolts, studs, and threaded rods. With a 1/2 in drive and a 7/8 in 6-point profile, this socket extends beyond standard deep sockets, helping you access tight spaces and complete challenging tasks with confidence. Built for professional use, it pairs robust materials with an industrial finish that stands up to daily shop wear.

Key advantages

• Premium Extra Deep Socket: 1/2 in drive, 7/8 in, 6-point geometry for solid fastener engagement.
• Extended reach: Extra depth reaches fasteners on long bolts, studs, and threaded rods where standard sockets fall short.
• Six-point design: Maximizes contact with fastener flats, reducing rounding and improving torque transfer.
• Radius corner design: Contacts flats rather than corners, preserving fastener geometry and enhancing grip.
• Precision fit: Machined to tight tolerances for secure engagement and reduced slippage in harsh conditions.
• Dual size markings: High-visibility laser-etched plus permanent stamped sizing for quick identification.
• Black phosphate finish: Industrial coating offering corrosion resistance for longer service life.
• ANSI/ASME compliant: Designed to meet recognized industry standards for reliable performance.

Durability and precision

Crafted from CR-MO alloy steel, the 228XD is built to withstand the impact forces typical of heavy-duty use. The radius corner geometry provides smoother engagement with fastener flats, helping reduce wear over time. The combination of a rugged finish and precise machining supports consistent torque transfer and a secure fit, even as you tackle stubborn hardware in tough environments.

Materials, finish, and compatibility

The black phosphate finish adds a layer of corrosion resistance, while the high-strength alloy composition delivers durability under high-torque impact loads. Meets or exceeds established standards, giving you confidence when selecting tools for professional tasks. The dual markings ensure you can quickly identify the correct size in cluttered toolboxes or on crowded job sites.

Real-world use cases

Ideal for automotive, industrial, and equipment maintenance tasks where fasteners sit in recessed or hard-to-reach locations. Examples include long bolts and studs on exhaust systems, frame assemblies, and machinery installations. While results vary by task, the extra depth and six-point grip can help you engage fasteners more securely with less slippage, potentially saving time during complex repairs.

Care and maintenance

• Wipe clean after use to prevent buildup of debris and moisture.
• Store in a dry, organized tray to preserve the finish and identification marks.
• Inspect for wear or rounding and replace if engagement becomes compromised.
