Self-clinching fastener insertion is a process of inserting engineered fasteners with compression force into a metal surface. These fasteners are engineered with knurls or expansive bases that “self-clinch” when mated with the appropriate size opening and can dramatically reduce the costs of tapping or masking threads for parts that require surface coating. Utilizing two self-clinching fastener insertion machines (commonly referred to as Pem Fasteners), Proto Precision can provide high volume, repeatable products with little or no custom tooling. Fasteners can be inserted prior to paint (masking available upon request) or after the paint process.
