CNC Fastener Insertion
Overview
Commonly referred to as “inserting”, Self-clinching fastener insertion is a process of inserting engineered fasteners, usually threaded, with hydraulic force into a metal surface. These fasteners are engineered with knurls or expansive bases that “self-clinch” when mated with the appropriate size opening in a sheet metal component. Utilising one automatic and three semi-automatic self-clinching fastener insertion machines, MTI can accurately process components in small to large volumes. Fasteners can be inserted before or after powder coating. Key advantages include:
- Provide strong threads or attachment points in metal as thin as 0.20 mm
- Drastically reduced installation and assembly times in comparison to “loose nuts, screws and bolts”
- Provide high pushout and torque-out resistance.
- Do not require special hole preparation, such as chamfering and deburring.
- Reverse side of metal sheet remains flush – no swaged rim protrusion.
- No retapping necessary after application.
- Low installed costs.
