Key Features

    These fasteners have been designed to provide permanent blind threads in thin sheet (from 1mm). Blind end prevents contamination from foreign bodies. Self-locating, they are easily installed into punched or drilled holes using any standard squeeze press. Ensure surfaces remain parallel for optimum installation. Available in steel or stainless steel. Optional finish – zinc plating on steel.

Advantages

       1. Body design protects internal threads from the entrance of foreign matter
       2. Available in heat-treated carbon steel with a zinc finish, as well as a 300 series stainless steel with a passivated finish.
       3. Available in sizes M3-M6  & 4-40 through ¼-20
