FOR THE PRECISE PINS YOU NEED FOR ANY APPLICATION, DISCOVER THE MEN OF STEEL.
At Robert A. Main & Sons, Manufacturing LLC we make quality metal parts our whole business and if a metal part you need doesn’t exist, we’ll make it. We manufacture products from round wire such as: basic steel, low carbon steel, medium carbon steel, high carbon steel, tool steel, music wire, and all types of stainless steel, monel, brass, copper, tungsten, special/unusual steels, pinned rolls and more.
Secondary operations can be performed in our plant for you as follows:
Heat treat, polish (regular or bright) [90% of our products are supplied heat treated and polished with costs that are extremely low], bend, knurl, flatten, thread, form, mill, drill, plate, tumble, butt chamfer, anneal and temper.
Main can drop ship for you, bulk package, by count, by weight, or envelope. In addition, we can head all points one way, do sub-assembly for you, drill holes, soften and supply you with cut-off wires to close tolerances, straighten and cut wires in any length up to 30″ long or longer by special request.
Our wire parts are made in diameters from .020″ to 7/16″ diameter – (and any size in between): in lengths from .125″ to 24″ long – tolerance on lengths is normally +/- 0.010”, diameters +/- 0.001” – other parts have tolerances as required.
