مقبس سداسي صدمي (1") من ساتا قياس (39mm) موديل (ST34827SC)

Key features include: 1" drive compatibility for high-torque impact tools; a 6-point fastener engagement for better torque transfer; off-corner loading to reduce fastener rounding; impact-grade chrome molybdenum steel for durability; black phosphate coating for corrosion and wear resistance; a large size marking for quick identification; and a 39mm size suitable for various large fasteners.

A 6-point design provides a larger contact area on the flat faces of a fastener, delivering a more secure grip and reducing the risk of rounding off corners under high torque. It’s especially beneficial for stubborn or oversized fasteners encountered in heavy-duty work.

This socket is built from premium chrome molybdenum steel, which offers excellent strength and durability under impact loading. It features a black phosphate coating that resists corrosion, rust, and wear, helping extend tool life and maintain a sharp appearance in tough working environments.

The socket is designed for use with 1" drive impact wrenches. It’s well-suited for large fasteners on automotive, construction, and heavy machinery applications where high torque and reliable engagement are required.

Off-corner loading minimizes edge or corner contact with the fastener, reducing the chance of rounding and damage under heavy torque. This helps preserve fastener integrity and improves torque transfer efficiency during demanding tasks.

Steps: (1) Ensure you’re using a genuine 1" drive impact wrench and the correct 39mm socket size. (2) Align the socket with the fastener squarely and push it fully onto the fastener. (3) Attach to the impact wrench securely and begin with moderate torque, increasing gradually as needed. (4) Avoid side loads or misalignment, which can cause damage. (5) After use, inspect for cracks or wear and store in a dry, organized tool chest.

Ideal for large automotive fasteners, heavy equipment and machinery maintenance, and construction tasks requiring high-torque removal or installation of large nuts and bolts. Its 39mm size and 1" drive make it versatile for many heavy-duty scenarios.

Keep it clean and dry after use, wipe away any debris, and store in a dry location to prevent rust. Regularly inspect for cracks or rounding, especially after high-torque sessions. If the socket shows noticeable wear, replace it to maintain safe and reliable performance.

If you’re working with different fastener sizes, consider these nearby options on Fepy.com: 41mm variant: https://fepy.com/product/sata-st34828sc-1-drive-6-point-impact-socket-41mm and 37mm variant: https://fepy.com/product/sata-st34826sc-1-drive-6-point-impact-socket-37mm. The 41mm version offers a slightly larger grip for bigger fasteners, while the 37mm version provides access to slightly smaller large fasteners. All are designed for 1" drive impact wrenches and share the same build quality and durability features.

This socket is specifically engineered for impact tools, using high-strength chrome molybdenum steel and a corrosion-resistant black phosphate coating. The 6-point design and off-corner loading help prevent rounding and withstand high torque, delivering greater durability and reliability in demanding environments where non-impact sockets may fail or wear quickly.

Yes. Always match the socket to a compatible 1" drive impact wrench, ensure the fastener size is appropriate for 39mm, avoid using misaligned or angled engagement, and limit peak torque to what your tool and fastener can safely handle. Wearing eye protection and keeping the workspace clear will help prevent injuries during high-torque tasks.

Consider the fastener size (39mm), the torque required, the material being fastened, and the working environment. If you’re consistently working with very large fasteners at high torque, this 39mm 1" drive 6-point socket offers secure engagement, durability, and resistance to wear, making it a strong value for heavy-duty tasks.
