Professional 3/4 Inch Drive Socket
The TEKTON SHD33121 is a 21 mm deep 6-point socket built for a 3/4 inch drive. It targets mechanics and technicians who need a single deep socket for heavy-duty fastener work. Buyers looking for a full socket set or multiple sizes will need additional pieces.
3/4 Inch Drive Compatibility
This socket only fits a 3/4 inch square drive ratchet or breaker bar. Smaller 1/2 inch or 3/8 inch drives cannot accept it, and larger 1 inch drives require an adapter not included here. Verify your drive tool matches this specification before purchase.
Direct Manufacturer Fulfilment
Orders valued at 75 or more ship free when fulfilled directly by TEKTON. Smaller orders do not qualify for that threshold. No case, rail or organiser is supplied with the socket itself.

Questions about this item
What does the 21 mm size mean when I use this socket on a fastener?
The 21 mm opening fits nuts and bolts with a 21 mm across-flats dimension, and the deep well reaches past the threads on longer studs.
How does the 3/4 inch drive square limit what I can connect to it?
It only accepts 3/4 inch drive ratchets, breaker bars or extensions; smaller 1/2 inch or larger 1 inch tools will not engage the square drive.
What clearance do I need around the socket to fit it onto a bolt head?
The 6-point deep socket requires enough room for its outer diameter and full depth to slide over the fastener without obstruction.
