Info

Self-Clinching Standoffs provide strong captivated reusable female threads in a spacer format in panels as thin as 1.0mm. Utilising a hexagon head and a special proven 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. Self-Clinching Standoffs are available in a range of thread sizes and lengths, in through-threaded, blind-threaded and clearance-hole styles. Manufactured from electro zinc plated carbon steel, 300 and 400 series stainless steel, aluminium and are suitable for installation in ductile panels with a recommended maximum hardness of 80 HRB for steel parts, 70 HRB for 300 series stainless steel parts, 88 HRB for 400 series stainless steel parts and 50 HRB for aluminium parts.
