Are roll pins and spring pins the same?
A spring pin is an unthreaded mechanical fastener that expands to securely fit in a hole. Spring pins, also known as roll pins, are designed to be inserted into a hole that has a smaller diameter than the pin.
What is a coiled spring pin?
Spiral pins are also referred to as coiled spring pins or, simply, coiled pins. They are a type of spring pin, typically produced by rolling a sheet of sprung steel into a spiral to form a pin. They’re used to provide enhanced strength, flexibility, and fatigue resistance.
Are roll pins hardened steel?
Roll pins are very hard indeed, heavily rolled and heat treated. I am guessing that the hardness is around 800 Vickers, not far off the same as a metal file and an HSS drill.
What size hole do you drill for a 3/32 roll pin?
Spring Roll Pins
| Spring Pins, Slotted Type | ||
|---|---|---|
| Nominal Size or Basic Pin Diameter | Recommended Hole Size | |
| 1/16 | 0.062 | 0.065 |
| 5/64 | 0.078 | 0.081 |
| 3/32 | 0.094 | 0.097 |
What are the sizes of roll pins?
Roll Pins
| Diameters | Lengths | |
|---|---|---|
| Metric | 1 – 12mm | 4 – 100mm |
| Imperial | 1/16 – 1/2″ | 3/16 – 4″ |
Can spring pins be reused?
Well-known member Things which only deform elastically (and spring back) are fine to re-use; think which deform plastically (so come out a different shape) aren’t.

Things which only deform elastically (and spring back) are fine to re-use; think which deform plastically (so come out a different shape) aren’t. I think roll pins are elastic.
Can you drill out roll pins?
Drill Out. Some roll pins may be so tight or rusted inside the hole that the only alternative is to completely remove the pin by drilling it out with a carbide bit. Caution must be exercised as the drill bit may attempt to wander off the center of the pin. This can cause a mis-centered or an oblong hole.
