Info
Self-Clinching Flush Head Studs for Stainless Steel  provide strong reusable captivated male threads in thin stainless steel panels. Utilising a special proven castellated clinch feature, this fastener has excellent torque-out, pull-through and push- out characteristics whilst providing a flush finish on the underside of the panel, meaning that minimal surface finishing is required after installation. Like all self clinching fasteners they are installed using a parallel squeezing action, so require access to both sides of the panel.   Flush Head Studs for Stainless Steel are available in a range of thread sizes and lengths, manufactured from hardened 400 series stainless steel and are suitable for installation in ductile stainless steel with a recommended maximum hardness of 92 HRB. Flush Head Studs for Stainless Steel can also be supplied with a dog-point thread lead-in to aid component assembly.
