Made from SAE 1035 carbon steel, these keys lock pulleys and gears tightly to transmission shafts. The key reaches into the keyway shaft to become firmly embedded. The key can rock in its seats and adjusts perfectly to an angular spine, providing a bearing surface throughout, and making rollover impossible. Stocked in thickness from 1/16" to 1/2" and lengths from 1/4" to 2 3/4".
