Roll Pins

Slotted roll pins are a heavy duty type of self retaining pin, where the spring steel they are made from allows the pin to sit in tension within the hole that they are fitted into. Slotted roll pins are also known as slotted spring pins, tension pins, split dowel pins and hollow spring pins. Conform to ISO 8752 / DIN 1481.

Spiral roll pins are similar to the slotted roll pin, but are constructed from a spiral of steel, forming a tube shape. These are stronger than the single coil of the rolled slotted pin, exerting pressure more evenly around it circumference, which helps to absorb vibrations better. These are also known as coiled spring pins and conform to ISO 8750.
