The concealed-head design maintains a smooth surface on the opposite side of installation, making them ideal for a variety of applications. Installation is straightforward using a hollow anvil and solid punch, with sheet preparation requiring only a milled blind hole to the recommended depth. With their aluminum construction, these studs offer durability and reliability, meeting RoHS compliance standards for environmental sustainability.
