Tom Servo Arm Spring Set - MST3K
Made of Stainless Spring Steel. Highly rust-resistant and can also be stretched without easily deforming.
Dimensions: 1" diameter x 1.3" long
Note: These can be used as replacements for the springs in the Bukoski's Servo kits but these wind the opposite direction so you will need to file or cut a small starting groove in the opposite direction on your servo hands.
$5.95 flat shipping, no matter what or how much you buy!
