SKU CH-WCS4-6F57E

3/4 Inch Drive Deep Socket

TEKTON SHD33120 is a 3/4 inch drive socket with a 20 mm deep 6-point opening. It is built for heavy-duty fastening where a standard socket cannot reach. Mechanics and technicians use it on large bolts in automotive and industrial work. The deep well clears long threads without binding.

Suited for high-torque manual or impact use

This socket fits 3/4 inch drive ratchets, breaker bars and impact guns. It serves professionals who need reach on 20 mm fasteners. It is not for smaller drive sizes such as 1/2 inch or 3/8 inch. Buyers needing other metric or SAE sizes must select different sockets.

20 mm 6-point deep opening

The 20 mm hex opening grips the flats of the fastener to reduce rounding. The deep profile accommodates extended threads and studs. This single dimension decides whether the socket matches the bolt you are turning.

Questions about this item

Will the 3/4 inch drive on the SHD33120 fit my existing ratchet and breaker bar?

The socket has a 3/4 inch square drive that matches any standard 3/4 inch drive ratchet, breaker bar or torque wrench you already own.

How can I verify the 6-point 20 mm deep socket is engaging the fastener correctly after setup?

The 6-point geometry grips the flat sides of a 20 mm nut or bolt head, so you feel solid contact without rounding the corners when torque is applied.

Does the SHD33120 come with any accessories or do I need to buy a 3/4 inch drive tool separately?

The box contains only the single 20 mm deep socket; a 3/4 inch drive ratchet, breaker bar or extension must be purchased separately if you do not already have one.
