FAQ
Frequently Asked Questions
Yes, in most practical contexts they are the same type of fastener. 'Circlip' is the more common term in British English and formal international standards (e.g., DIN), while 'snap ring' is prevalent in American English.
It is generally not recommended. Snap rings are designed to spring into place and can lose tension or become deformed upon removal. Reuse can compromise their retaining force and lead to mechanical failure.
Specialised snap ring pliers (circlip pliers) are used. They have tips that fit into the holes or notches on the ring. Internal snap rings require expanding pliers, while external snap rings require contracting pliers.
An internal snap ring fits into a groove inside a housing or bore to retain a component from the outside. An external snap ring fits onto a groove on a shaft or pin to retain components from the inside.
