S-Type Captive Threaded Stud Inserts function like the Knurled Blind Threaded Inserts, but leave a threaded stud protruding from the panel after installation. Components can then be attached and secured by a mating nut. These studs can be used in place of clinch or weld studs, before or after finish. Optional head designs include a weathertight PVC foam sealed head, or a wedged head for more torque capabilities. As these are installed, the knurled body expands 360º to fill the hole, creating exceptional torque strength and resistance to vibration. A backside flange is also formed, even in multiple thicknesses of materials without any need for adjustments.
