4mm diameter Spiral Roll Pins in 301 Stainless Steel

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.
