1 Thread Form & ie Button Units For Type A, B, AB, & C Metal Screws ayton Thread Form & ie Button Units offer you a single-step method for punching and forming threads. ayton Thread Form works by punching the hole, lancing the material, and cutting a helical spiral in the material to form the proper thread helix for the desired type of metal screw. Thread Form creates a complete self-locking fastening system that holds the screws more tightly with metal tension thereby reducing vibration, cutting assembly costs, and increasing productivity. Single-step, in-die process provides exceptional holding power. Cost-effective. Creates superior self-locking system.

4 Options Inverted Form For design flexibility, an inverted form is available. Simply specify Inverted Form on your order. Material Thickness If thicker material is used, the area can be coined in a previous station in the die to thin the material. Coining hardens the material, and affects tool life. Thread Form & ie Button Units Form Applications of 200,000+ For larger runs, it is recommended that a keyhole shape be punched in a previous station. The keyhole shaped insert eliminates the wear created from the lance during the forming operation. C4 A A ayton rogress C4 standard punch and die button shape is used. The table below shows the keyhole dimensions and the die button clearance for each of the thread sizes.
