Etokfoks Adjustable Screw Jack Two Pack Heavy Duty Machinist Jack Posts From 2 75 In To 4 25 In For Leveling And Support

This two pack of adjustable screw jacks offers a height range from 2 75 in to 4 25 in with a 2 in diameter so you can support and level heavy objects securely when working with machinery assemblies or other stable loads in the workshop

Each machinist jack is made of strong 45 steel that is wear resistant with a load capacity of 5 tons to provide reliable stability and efficient performance for repeated use under demanding conditions in industrial and maintenance tasks

These adjustable jacks are essential assistants for positioning large machines setting up equipment leveling on milling and drilling machines and serving as a pad or support under a pressing board during precision alignment work

The screw jack rotates smoothly so you can raise or lower the post to a flexible height and select an appropriate size to suit your specific application whether you are aligning machine beds supporting fixtures or leveling workpieces

After adjusting the screw to the desired height you can tighten and lock it with the nut to enhance security and help prevent position changes during operation so the supported load remains steady while you work around it

A patterned design on the bottom of each jack enhances friction and stability which helps resist slipping during leveling and machine setup work and contributes to safer more accurate support on firm flat surfaces
