Rubber well nuts

A elastic and virbation-reducing connection for sensitive materials. The EPDM-body protects the cap nut against corrosion, provides oil resistance and is non-conductive. This product can be applied one-sided. When screw-mounted the elastic body engages itself to a secure and dense closing head. In blind holes the cap nut will be pressed onto the hole wall serving as a frictional connection.
