Stainless Steel Metric Hex Nuts, Square Nuts & Flange Nuts for use in applications requiring general corrosion resistance
ASTM F836M Specification covers the chemical and mechanical requirements for Metric Hex Nuts, Square Nuts & Flange Nuts with nominal thread diameters M1.6 through M36 and intended for use in engineering applications requiring general corrosion resistance. Eight groups of stainless steel alloys are covered, including three austenitic (Grades A1, A2, and A4), one ferritic (Grade F1), three martensitic (Grades C1, C3, and C4), and one precipitation hardening (Grade P1). Seventeen property classes are covered, including nine austenitic, one ferritic, six martensitic, and one precipitation hardening
Product Shall be Marked with our manufacturing trade mark Adfast Component LTD along with the designated Grade.
Grade and manufacturer’s identification symbols shall be applied to one end of studs and to the heads of bolts and screws of all sizes. (If the available area is inadequate, the grade symbol may be marked on one end and the manufacturer’s identification symbol marked on the other end.) For bolts and screws smaller than 1⁄4 in. [6 mm] in diameter and studs smaller than 3⁄8 in. [10 mm] in diameter and for 1⁄4 in. [6 mm] in diameter studs requiring more than a total of three symbols, the marking shall be a matter of agreement between the purchaser and the manufacturer.
