SATA ST16311SC 3/4" Drive 6 Point Socket 1.3/8"

Key specs include: 3/4\" drive compatibility, 6-point fastener end design, chrome vanadium steel construction with a chrome-plated finish, off-corner loading design for reduced fastener rounding, large size markings, and dual SAE/metric identification to help you quickly confirm the socket size.

The 6-point configuration provides a strong grip on the flats of fasteners, distributes torque more evenly, and minimizes rounding under high torque. This leads to longer tool life and safer operation when dealing with stubborn or seized fasteners.

The socket features large size markings for quick identification and uses a dual marking system (SAE) with a knurled line (MM) to distinguish standard vs metric sizing, helping you select the right tool at a glance.

It's well-suited for automotive repair, heavy machinery maintenance, and any task that requires high torque on fasteners sized around 1-3/8" head size. Its robust chrome plating also stands up to corrosive environments encountered in shop work.

Use a compatible 3/4\" drive ratchet and ensure the fastener seats fully into the socket before applying torque. The off-corner loading design helps prevent rounding, and a proper seating reduces slippage and improves safety during use.

The socket is made from chrome vanadium steel and finished with chrome plating. This combination provides excellent strength, wear resistance, and corrosion resistance for long-term tool life in challenging environments.

This ST16311SC offers a high-torque capable 6-point design with durable chrome vanadium construction and easy size identification at a competitive price point. When comparing value, consider tool longevity, torque endurance, and the convenience of SAE/metric markings that save time on job sites.

This socket is engineered for 3/4\" drive ratchets and will work with compatible 3/4\" drive ratchets from multiple brands, provided the drive size matches. Always ensure proper seating to maximize safety and performance.

Yes. Ensure the fastener is properly aligned and seated before applying torque, use a compatible ratchet to avoid over-torquing, keep the socket clean and free of debris, and inspect the socket for cracks or wear after heavy use to prevent sudden tool failure.

Absolutely. If you need more sizes or a broader set, you can explore other 3/4\" drive 6-point sockets and complete tool sets in Fepy’s catalog, often grouped by drive size and marked with SAE/metric identifications for quick comparison.

Wipe the socket after use to remove oil, coolant, and grime; store it in a dry, organized toolbox; and periodically inspect for chrome wear or edge rounding. Proper storage and cleaning help preserve the chrome finish and structural integrity.
