Manufacturing note
Nascent fittings produces high quality stainless steel hexagonal bars in stainless steel grades. It also manufactures corrosion resistance quality of stainless steel hexagonal bars which make them suitable for various applications. Nascent supplies stainless steel hexagonal bars cut to size in both small and large widths. The hexagonal bars range in thickness from 12 mm to 75 mm and are accompanied by Ultrasonic Test Reports, Chemical Test Reports, and Mechanical Test Reports. Our stainless steel bright hex bar is flexible to use in different manufacturing applications due to its high strength and corrosion resistance durability. It is also used in the manufacturing of nuts, valves, hose ends, fasteners and hex bolts. Hexagonal bars, also known as hex bars, are used for nuts, bolts and fasteners in a variety of industries such as; electrical, heating and plumbing and marine. Hex bars are also used in applications where the machining process is assisted through the shape or grade of material. Stainless steel square bars are certified to the highest industry standards and are accompanied by a Mill Test Certificate.
