Stanley PROTO J74418MP 18mm Universal Impact Socket, 1/2" Drive, 6 Point
- The PROTO J74418MP universal impact socket features a ½ inch drive and 18 mm metric size with a flex-joint design, offering professional-grade access and power for stubborn fasteners in automotive, industrial or maintenance settings.
- Features
- Ball and spring design which allows for a 30° working angle.
- Smooth 360° rotation.
- Proto 6 Point Impact Sockets are ideal for use on stubborn or damaged fasteners, and also on fasteners made from soft materials.
- The TorquePlus design is a high performance drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners.
- The TorquePlus configuration employs a radius-corner design, shifting contact area and stress away from the fastener corners and distributing contact stresses over a large area of the socket, minimizing slippage.
- The TorquePlus internal design minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded, or rusted fasteners.

PROTO’s J74418MP universal impact socket brings superior design for mechanics, service techs and industrial users who need access and strength in one socket. With its flex-joint articulation, 6-point contact and high-quality alloy steel construction, it’s engineered to tackle seized or obstructed 18 mm fasteners with confidence.
Q: Will this socket connect to my standard ½ inch drive impact wrench?
A: Yes — the PROTO J74418MP features a ½ inch square drive and is designed for use with standard ½ inch drive impact wrenches.
Q: What advantages does the flex-joint (universal) design provide?
A: The flex-joint design allows the socket head to articulate up to ~30°, improving access to fasteners located in awkward or angled positions where a straight socket might not reach.
Q: Why choose this socket over a standard fixed socket?
A: Because of the 6-point geometry combined with PROTO’s Radius-Corner TorquePlus design, this socket offers improved engagement on fastener flats, reduced rounding risk, and better performance on damaged or stubborn fasteners compared with standard sockets.
