SATA GL16511 3/4" Drive 12 Point Socket 1.3/8"

Key features include a double hex 12-point fastener end for secure grip, off-corner loading to reduce rounding, large markings for easy size identification, and dual SAE/metric markings to help identify standards quickly.

Drive size: 3/4 inch. Socket size: 1-3/8 inch opening. Material: chrome vanadium steel. Finish: chrome plated. Geometry: 12-point. Markings: large size numerals with dual SAE and metric indicators. Compatible with 3/4 inch drive tools and designed for heavy-duty use.

A 12-point socket provides quicker engagement and easier alignment in tight spaces because it has more contact points with the fastener. A 6-point socket generally offers stronger grip and is less prone to rounding when the fit is precise and high torque is involved. For fast, flexible engagement in confined areas, go 12-point; for maximum grip on perfectly seated fasteners, 6-point can be preferable.

It's well-suited for large bolts and high-torque assemblies in automotive work, machinery maintenance, industrial equipment, and heavy-duty construction projects where 1-3/8 inch fasteners and a 3/4 inch drive are common.

Attach the socket securely to a compatible 3/4 inch drive ratchet, ensure the 12-point opening aligns with the fastener, seat fully, and apply steady torque. Use appropriate extensions or adapters if needed, and avoid banging the ratchet to engage the fastener.

The socket features large size markings on the exterior, with dual SAE and metric indicators to help you confirm the correct size at a glance.

Keep it clean and dry, wipe away grease or debris after use, and store it in a protective case or tray with your other sockets to prevent rust and impact damage. A light coating of oil can help prevent corrosion if stored for extended periods.

Wear eye protection, ensure you’re using the correct size and drive, keep hands clear of moving parts, avoid using worn or damaged fasteners, and do not use the tool for applications beyond its rated purpose or torque range.

Yes. It’s designed for heavy-duty tasks with chrome vanadium steel and a chrome-plated finish that resists corrosion, providing durability and extended service life in tough conditions.

The combination of durable construction, corrosion resistance, and the convenience of large markings and dual sizing indicators typically provides solid long-term value by reducing replacements and improving efficiency in professional workflows.
