Profile: Zygology Ltd. specializes in offering assembly solutions and industrial fasteners. Speed fasteners are installed using a unique repetition mandrel system. During placement, the tool pulls the mandrel through the rivet, giving both axial and radial expansion providing clamp and hole fill. Structural blind fasteners are designed for rapid assembly where high shear and tensile strength is required. Unlike ordinary break stem rivets, in structural breakstem fasteners, the mandrel becomes an integral part of the placed fastener adding considerable strength to the assembled components.
