Questions about this item

What does the 6-point drive design mean when I use this socket on a fastener?

The six-point drive contacts the flats of a 7/8 inch fastener rather than the corners, reducing the chance of rounding off the head under high torque.

How does the 3/4 inch drive square affect the tools I can connect to this socket?

The 3/4 inch drive square fits any 3/4 inch drive ratchet, breaker bar or extension, and the ANSI-standard dimensions ensure secure engagement with those tools.

What clearance do I need around a 7/8 inch fastener for this socket to fit?

The socket's outer diameter is sized for a 7/8 inch hex fastener, so you need enough space for the socket body to slide over the head without obstruction from adjacent components.
