Slotted Tapered Shims
The slot lets you install these rigid shims around screws. Shims are made of plastic to resist moisture and prevent rot. Use them to align cabinets, doors, and windows, or for other rough leveling.

Maintenance-Free Lockable Turntables
The sealed ball bearings will never need additional lubrication. These turntables lock into one of four positions. To unlock, pull the ring on the spring-loaded locking pin and turn it 90°. Turntables add rotational positioning to machinery and equipment.

Ball Screws and Nuts
Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start ball screws and nuts, they have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts. To ensure compatibility, select components that have the same thread direction and size. Ball nuts are furnished with a tube to keep ball bearings in place. Do not remove the tube until you are ready to install the nuts onto the screws.
Black-oxide alloy steel ball screws and nuts have mild corrosion resistance.
Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.
