What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve collets, are small components that fit into a groove on the valve stem. They work with the valve spring retainer to hold the valve spring assembly securely in place on the valve.

What does the '10 DEG BEAD' refer to?

The '10 DEG BEAD' refers to the angle of the groove or taper on the keeper itself. This specific angle is designed to mate with a corresponding angle on the valve spring retainer, creating a strong and secure lock.

Are these keepers compatible with all valve springs?

These keepers are specifically designed for 7mm valve stems and a 10-degree retainer angle. You should confirm that your valve springs and retainers use these specifications for proper compatibility.
