Info
Self-Clinching High Strength Studs provide high strength captivated male threads in thin panels. This fastener does not install fully flush on the underside of the panel. Utilising a special proven castellated clinch feature, this fastener has very high 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.   High Strength Studs are available in a range of thread sizes and lengths, manufactured from electro zinc plated through-hardened steel, 300 series stainless steel, phosphor bronze and are suitable for installation in ductile panels with a recommended maximum hardness of 85 HRB for steel parts, 70 HRB for 300 series stainless steel parts and 55 HRB for phosphor bronze parts. High Strength Studs can also be supplied with a dog-point thread lead-in to aid component assembly.
