Info
Self-Clinching Concealed Head Standoffs provide strong captivated female threads in panels as thin as 1.60mm. Utilising 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 Standoffs are available in a range of thread sizes and lengths, manufactured from 300 series stainless steel and are suitable for installation in ductile panels with a recommended maximum hardness of 70 HRB.
