Metal Gears and Gear Racks—20° Pressure Angle
The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. Compared to plastic gears and racks, they’re better for high-load, high-speed, and heavy duty applications. Also known as spur gears.
Combine gears with different numbers of teeth to change speed and torque in your assembly. Combine a gear and rack to convert rotary motion into linear motion. To minimize your footprint, mount one or more standard gears inside of an internal gear.
For components to mesh correctly, they must have the same pressure angle and pitch/module.
Brass gears and racks are easy to machine, so you can add your own mounting holes and make other alterations. They won't rust when exposed to water.

Grab Latch with
Force Adjustment Screw
Grab latches work well on lightweight doors. They have a catch that grabs and holds a ball, latching screw, or strike plate to keep doors shut. Rail-to-panel grab latches have a ball that threads into a tapped hole on the panel.
Grab latches with left, right, and front grab direction work on sliding or swinging doors when the ball or strike plate is clipped into the front or side of the latch. Those with a force adjustment screw let you control how hard it is to open and close the latch.
