Screw Jack 1in-8 UNC 1 12in Long Swivel Cup

The Screw Jack 1in-8 UNC 1 12in Long Swivel Cup by WEHRS MACHINE is a precision-engineered jack bolt designed for heavy-duty load adjustment and equipment stabilization in tactical, military, and industrial applications. This component serves a critical role in systems requiring fine-threaded vertical or lateral positioning, where controlled load distribution and secure locking are non-negotiable. Built by a manufacturer with deep expertise in mechanical fastening systems, this swivel cup jack addresses the specific demands of operators and technicians who require repeatability and reliability under demanding field conditions.

Manufactured from hardened steel and finished with a durable black powder coat, the Screw Jack 1in-8 UNC 1 12in Long Swivel Cup delivers corrosion resistance and superior wear characteristics across extended operational cycles. The 1-inch diameter 8 UNC (Unified National Coarse) thread pitch provides optimal load-bearing surface area while maintaining smooth, predictable rotation without binding or slippage. The 12-inch extended length accommodates both deep-set and surface-mounted installations, and the integrated swivel cup design minimizes rotational friction while distributing contact pressure evenly across mating surfaces. A slic pin is included to secure the jack position, preventing accidental drift during extended use or vibration exposure.

Law enforcement and military personnel rely on this component for vehicle stabilization systems, equipment mounting platforms, and load-bearing fixtures in armored or specialized vehicles. The swivel cup feature is particularly valuable when working on uneven terrain or when precise leveling under side-load conditions is required. Installation is straightforward for technicians familiar with standard threaded fasteners; the jack threads smoothly into prepared 1-inch 8 UNC mounting points and locks securely with the included pin. Weighing 2.04 lbs, it remains lightweight enough for portable or modular systems while maintaining the structural integrity demanded by tactical environments.
