The Proto 5784 is a new, USA-made 3/4 in drive, 2-5/8 in 12-point standard (non-deep) hand socket manufactured to Proto's Professional Series specifications. Constructed from forged alloy steel with a satin chrome finish, the 12-point configuration allows engagement at every 30° of rotation, providing added flexibility in tight-access applications where a 6-point socket cannot be fully positioned. The Proto 5784 is designed for use with 3/4 in drive ratchets, breaker bars, torque wrenches, and drive extensions; the large 2-5/8 in opening is typical for heavy equipment, agricultural machinery, and structural fastener applications. All markings visible in the photos — "5784 PROTO PROFESSIONAL" and "2-5/8" — are consistent with the published Proto catalog number and size designation for this socket.
