3/4" Drive 46mm 12pt Socket
The Powerbuilt 643240 is a 3/4 inch drive socket with a 46mm opening and twelve-point geometry. It fits heavy-duty fasteners found on commercial vehicles, agricultural equipment and industrial machinery. Professional technicians and serious hobbyists use it for high-torque applications where smaller drives cannot deliver enough leverage. This single socket adds a specific large size to an existing 3/4 inch drive set.
No bundled accessories or software
The product ships as a single socket with no case, no extension bars, no adapters and no digital content. Buyers who want a complete storage solution or a full range of sizes must purchase those items separately. The absence of bundled items keeps the purchase focused on replacing or expanding one specific socket size only.
Check drive compatibility and Proposition 65 notice
Verify that your ratchet, breaker bar or impact gun uses a 3/4 inch square drive before ordering. The socket is marked with a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. Users should follow local safety regulations and wear appropriate protective equipment when handling the tool.

Questions about this item
Will the 12-point 46 mm socket need periodic replacement under normal use?
The chrome-vanadium socket is built for professional torque loads; inspect the drive square and 12-point walls for rounding or cracks after heavy jobs and replace only if wear is visible.
What is the first limitation when the 3/4" drive 46 mm socket is used continuously on high-torque fasteners?
The 12-point geometry distributes load across more contact area than a 6-point, but sustained extreme torque can still deform the fastener corners before the socket itself yields.
Does the 46 mm 12-point socket generate noticeable heat or noise during all-day use in a busy shop?
No — it is a solid steel hand tool with no moving parts, so it produces no operational noise and only absorbs ambient heat from the fastener or impact gun.
