More secure attachment of vehicle components
Autospec self-clinching fasteners are designed to reduce the number of parts needed for attachment, accelerate assembly, and promote neater and lighter component designs
They are available in dozens of types and thousands of variations, including free-running, self-locking, floating, and blind hole types meeting unified, ISO, and MIL standards.
Self-clinching fasteners can be installed permanently in metal sheets as thin as 0.51mm and can eliminate a need for washers, lock washers, nuts, and bolts to attach components.
Since they become an integral part of a sheet in which they are installed and reduce the amount of necessary attaching hardware, these types of fasteners promote quicker product assembly and reduced costs for applications including electronics, communications, aerospace, and automotive products and components.
Installation of self-clinching fasteners is accomplished simply by pressing the fastener into place in a properly sized drilled or punched hole.
This process causes displaced sheet material to cold flow into a specially designed annular recess in the shank or pilot of the fastener, locking the fastener in place.
A serrated clinching ring, knurl, ribs, or hex head prevents the fastener from rotating in the metal when tightening torque is applied to the mating screw or nut.
