Snap-on FSUM18A 3/8 Inch Drive Swivel Socket 18mm

The Snap-on FSUM18A is a 3/8-inch drive shallow universal socket sized for 18 mm metric fasteners. This six-point socket uses Flank Drive technology to engage the fastener on its flats for better torque transfer and reduced cam-out, while the swivel head provides a full range of motion to reach fasteners in tight spaces. The shallow design keeps the tool low-profile for access in cramped engine bays, beneath dashboards, or crowded mechanical assemblies, and it pairs with a standard 3/8" drive ratchet or extension bar. Ideal for automotive and equipment maintenance where 18 mm bolts or nuts are encountered, FSUM18A belongs to Snap-on's Flank Drive Universal socket family, delivering reliable grip and versatility for metric fasteners in challenging angles. The swivel capability helps align the socket to the fastener's orientation, reducing wrist strain and improving accessibility when working in confined areas.
