Our review of the Sunex Tools 1 in drive 6 point impact socket 3-1/8 in finds it best suited to technicians and truck mechanics who need a heavy-duty, well-made socket for large fasteners.

Key Features

• Material: Made from CR-MO alloy steel for improved wear resistance and a longer service life under heavy impact use.
• Design: 6 point configuration provides secure engagement with hex fasteners to reduce rounding and slipping.
• Drive size: 1 in drive accommodates large impact wrenches commonly used in commercial and heavy equipment work.
• Length: 3-1/8 in standard length gives a balance of reach and control for recessed or stubborn fasteners.
• Case: Comes in a double latch blow mold case for organized storage and secure transport to the jobsite.

Who It's For

This socket is aimed at professional mechanics, fleet maintenance shops, and anyone who regularly works on heavy trucks, trailers, or industrial equipment where large fasteners and square drive tools are standard. The 1 in drive and 6 point profile match the demands of commercial service bays and roadside repair tasks.

Casual DIYers and light automotive enthusiasts should look elsewhere unless they specifically need a 1 in drive size; smaller drives and sockets are more appropriate and economical for routine home projects.

Pros & Cons

• Heavy-duty CR-MO alloy construction for long-term durability and resistance to impact damage.
