The automotive industry uses clinching studs that are pressed into mating materials such as steel plates. To meet the requirements for higher precision and quality products, Nitto Seiko developed JOISTUD-S to reduce warpage and burrs while providing greater anti-rotation.
They conducted research using manufacturing and dies making technologies to develop JOISTUD-HT with high anti-rotation capability, JOISTUD-SS with space saving function, JOISTUD-WP with water resistant function and JOISTUD-S with high strength. JOISTUD-WP is a product with water resistant function. Like JOISTUD-S, JOISTUD-HT can be simply pressed onto fastening elements to achieve higher product quality than ever before, providing strong support for customers' production.
While conventional clinching stud bolts has an evenly thick leaf-shaped protruding anti-rotation part, the JOISTUD series has an anti-rotation protruding part with a ring design only on the edge of the leaf. The anti-rotation part is also designed to prevent the buckling of the fastener. In addition, the groove inside the anti-rotation protrusion can accommodate the fastener that is deformed during pressing, preventing the deformed part from protruding toward the screw and forming burrs, and increasing the anti-rotation capability in the rotation direction.
