Screw Jack 1in-8 UNC 10in Long Swivel Cup

The Screw Jack 1in-8 UNC 10in Long Swivel Cup from WEHRS MACHINE is purpose-built for mechanics and fabricators working on engine hoists, transmission jacks, and custom lifting equipment. This precision screw jack provides controlled vertical adjustment on shop equipment where reliability and repeatability matter most. Whether you're raising a vehicle for undercarriage work, positioning an engine for installation, or fine-tuning hoist height on a home or professional lift, this swivel-cup design distributes load pressure evenly and prevents point-contact damage to delicate engine blocks, transmission housings, and subframes.

The 1-inch diameter, 8 threads-per-inch (UNC) design delivers smooth, predictable travel with minimal backlash—critical for safe load positioning during engine swaps, suspension work, or transmission drops. The 10-inch extended length allows adequate clearance when used with deep-pocket lifting brackets or custom fabrications, while the integral swivel cup automatically compensates for angular loads and prevents binding during angled raises. This single-piece construction eliminates connection points that could fail under shock loads, and the proven screw-jack mechanism requires no hydraulic fluid, air compressors, or external power—just hand-cranked or low-speed drill operation. The compact 1.67-pound weight ensures easy portability between bays, and the precision-machined cup face prevents marring of engine valley pans or transmission bell housings.

This screw jack is ideal for technicians building custom engine hoists, restorers fabricating transmission stands, and fabrication shops constructing load-handling fixtures. The UNC thread standard ensures compatibility with standard nuts and couplings, making integration into larger lift assemblies straightforward. Pair this with a hand crank or corded drill for infinite height stops—no pneumatic waste, no fluid seepage onto freshly painted engine bays. For any mechanic serious about safe, damage-free equipment handling, this WEHRS MACHINE unit represents the professional standard.
