Description : F-HFH-Thread ø-Length-Finish : eg F-HFH-M4-16-Z

Unlike our Flush Head Clinch Studs these fasteners do not install flush on the back of the material. Install using a squeezing action - the material is displaced in to the coining ring thus firmly fixing the fastener.

Available in Steel and Stainless Steel in thread sizes M5 - M10.
