Often tiny, yet indispensable — a problem to the executive, engineer and experimenter until the right SOURCE is found. Our mission is to be that source — originative, thorough and trustworthy. We are not jobbers. We actually create and manufacture, producing parts and hardware here under one roof. We specialize in metal stampings, screw machine parts of brass and steel, and insulating materials. We stock a complete line of screws, nuts, washers, grommets and assorted hardware for immediate shipment.
