Info
Self-Clinching Thin Panel Studs provide strong captivated male threads in panels as thin as 0.51mm. This fastener does not install fully flush on the underside of the panel. Utilising a special proven castellated clinch feature, this fastener has good torque-out, pull-through and push-out characteristics whilst providing minimal protrusion on the underside of the panel (refer to S dimension). Like all self clinching fasteners they are installed using a parallel squeezing action, so require access to both sides of the panel.   Reduced Head Studs are available in a range of thread sizes and lengths, manufactured from electro zinc plated steel, 300 series stainless steel and are suitable for installation in ductile steel and aluminium panels with a recommended maximum hardness of 80 HRB for steel parts and 70 HRB for 300 series stainless steel parts. Reduced Head Studs can also be supplied with a dog-point thread lead-in to aid component assembly.
