Self-Clinching Concealed Head Studs provide strong captivated male threads in panels as thin as 1.60mm. Utilizing a special proven clinch feature, this fastener has excellent pull-out and torque-out characteristics. Installed into a pre-prepared milled blind hole, it leaves the underside of the panel intact. Like all self-clinching fasteners they are installed using a parallel squeezing action, so require access to both sides of the panel. Concealed Head Studs are available in a range of thread sizes and lengths, manufactured from 300 series stainless steel, aluminum and are suitable for installation in ductile panels with a recommended maximum hardness of 70 HRB for stainless steel parts and 50 HRB for aluminum parts.


300 Series Stainless Steel (A2) parts are suitable for installation in ductile panels with a maximum recommended hardness of 70 HRB. Aluminum (AL) parts are suitable for installation in ductile panels with a maximum recommended hardness of 50 HRB.
