Screw Jack 3/4in-10 UNC 10in Long Swivel Cup

The Screw Jack 3/4in-10 UNC 10in Long Swivel Cup is a precision bottle jack component designed for automotive enthusiasts and professional mechanics who require reliability during frame work, suspension modifications, and engine bay operations. This heavy-duty screw jack assembly acts as the load-bearing interface between your lifting equipment and vehicle contact points, ensuring safe and controlled elevation during restoration projects and structural repairs.

Built with a 3/4 inch–10 UNC (Unified National Coarse) threaded specification, this jack features a swivel cup head design that rotates freely to accommodate angled lifting surfaces and uneven contact geometry common in automotive work. The swivel mechanism reduces binding and ensures threads remain perpendicular to the load path, preventing cross-threading and extending service life under repeated use. With compact dimensions, this component integrates seamlessly into standard bottle jack assemblies and aftermarket lifting systems.

This screw jack assembly is ideal for fabricators, transmission specialists, and anyone involved in automotive restoration or modification. Its design prevents damage to painted surfaces and distributes load evenly across contact areas, making it essential for anyone looking to perform precise lifting tasks safely.
