Questions about this product
- What does a QX219 index plunger do?
- It's a spring-loaded lock pin for quick, repeatable positioning. You pull it to release and let the spring return it to lock, all by hand. People use it to hold jigs, fixtures, and tooling plates in place.
- What thread sizes does this plunger come in?
- It's available in M10, M12, M16, and M20. Larger sizes suit bigger bores and heavier loads. Match the thread to your fixture's tapped hole and the force you need to hold.
- Is carbon steel or stainless steel better here?
- Both are offered. Carbon steel is harder, around 40-50 HRC, and works for standard environments. Stainless steel resists corrosion better, so pick it for damp or washdown areas. The spring is steel rated roughly -30C to +120C.
