Assembly screws are specially engineered for cabinet installation and box construction applications, featuring a unique design that acts like steel dowels to form strong, stiff butt joints. These fasteners incorporate a large shoulder under the head that locks the screw into the material and prevents pulling through into softer substrates. One of the key advantages of these assembly screws is their reusability—they can be removed and reinstalled several times without loss of holding power, making them ideal for applications requiring maintenance access or periodic disassembly. Manufactured with precision threading and passivation processes under ISO working instruction compliance, our SEMS and assembly screws deliver reliable performance across diverse industrial applications.
