Almost 20,000 pieces of these custom long machine screws were manufactured for our injection molding customer, made using 302 stainless steel material with plain finish. 4/40 thread was incorporated with 1" of usable thread minimum on each screw. Overall length was set to 4.625"-4.725" and the head was a standard philips pan head for a #4 machine screw. Concentricity was the more difficult aspect of these parts, with the combination of length and #4 diameter making it almost impossible to keep the parts straight after packaging.
