7/8-Inch Twist Socket

The Lock Technology 4400-40 is a 7/8-inch twist socket built for automotive service tasks. It fits fasteners of that exact size and is sold as a new tool. The manufacturer listed the item in February 2025 under the Lock Technology brand.

Mechanics needing a single 7/8-inch socket

This socket suits technicians who only require one 7/8-inch drive tool for transmission or general repairs. Buyers needing a full socket set, multiple sizes or a ratchet included should look at broader kits instead.

7/8-inch drive size

The 7/8-inch opening is the sole specification that determines whether this socket matches the fastener you are working on. Verify that dimension against the component before purchase.

Questions about this item

Will the 4400-40 7/8" twist socket fit the drain plug on my older transmission without rounding the corners?

The 7/8 inch opening matches fasteners of that size; verify the plug hex on your specific unit before use.

How can I confirm the 4400-40 twist socket is engaging the fastener correctly after positioning it?

The twist mechanism grips the flats when turned; smooth rotation without slipping shows proper engagement.

Does the 4400-40 package include an extension or ratchet, or must I supply my own drive tools?

Only the 7/8 inch twist socket is included; a compatible ratchet or breaker bar is purchased separately.
