Push on fasteners are a type of hardware component that allow other components to be quickly and securely attached to a smooth linear shaft. They are typically made from stainless or spring steel to ensure a secure hold. Once applied, push on fasteners are permanent and cannot be removed.

Types of push on fasteners

1. Push on nuts: they are the most common type of push on fastener. These are most commonly known as external fixing washers, or push on retainers.
2. Push on hat retainers: they consist of a cap that covers the end of the rod or shaft to provide additional protection to tools.
3. Speed nut: a speed nut works by sliding onto the shaft in a radial (circular) motion which is then locked into position for a secure fit.
4. Push-on bolt retainer: they have bolts and screws that hold them in place in a panel construction while a traditional nut is established.
