Metric Fastening Pins & Ring Fasteners


Industrial metric pins are a type of non-threaded fastener that can be used to hold material together or hold an item in place. They are often used in areas where applying a threaded fastener is impossible or undesirable. Industrial ring fasteners are used on a shaft or in a hole to hold assemblies in place. Both pin fasteners and ring fasteners are available in many different styles, sizes, and materials.

We offer wholesale pricing and same-day shipping, with most orders arriving within two business days. Between our five stocking locations in the US and our purchasing office in Germany, we are confident that we can provide the exact metric ring or fastening pin you require.
