Steel Grades A, C, 2H, DH, DH3 Heavy Hex Nut Properties

Description	A six sided internally threaded fastener which is both thicker and wider than a same-sized finished nut. Nuts size 7/16 and smaller shall be double chamfered. Larger sizes are either double chamfered or chamfered on top with a washer faced bearing surface.
Applications & Advantages	The strongest of all comparably graded nuts because of its greater length of thread engegement and greater resistance to dilation (widening or stretching). Grade-A nuts are used with low carbon heavy hex bolts. Grade-C nuts are recommended for use with A-325 structural bolts. Grade-2H nuts are recommended for use with bolts in high-pressure and high-temperature applications. Grade-DH nuts are recommended for use with A-490, Type-1 structural bolts. Grade-DH3 nuts are for use with A-490, Type-3 structural bolts.
Material	Nuts are to be made from a steel that conforms to the following chemical composition requirements (heat analysis): Grades-A and C: Carbon: .55% max Phosphorus: .12% max Sulfur: .023% max Grade-2H: Carbon: .40% min Manganese: 1.00% max Phosphorus: .12% max Sulfur: .05% max Silicon: .40% max Grade-DH: Carbon: .20-.55% Manganese: .60% min Phosphorus: .04% max Sulfur: .05% max Grade-DH3: Carbon: .02-.53% Manganese: .40% min Phosphorus: .046% max Sulfur: .05% max Copper: .20% min Chromium: .45% min (Either Nickel: .20% min or Molybdenum: 15% min may be used).
Heat Treatment	Grade-2H" Shall be heat treated by quenching in a liquid medium from a temperature above the transformation temperature and tempered at a temperature of at least 850°F. Grades- C, DH and DH3: Shall be heat treated by quenching in a liquid medium from a temperature above the transformation temperature and tempered at a temperature of at least 800°F.
Core Hardness	Grade-A: Rockwell B68 - C32 Grade-C: Rockwell B78 - C38 Grades-2H, DH, and DH3: Rockwell C24 - C38
Proof Load	Grade-A: Course: 100,000 psi Fine: 90,000 psi Grade-C: 144,000 psi Grade-2H: 150,000 psi Grades-DH and DH3: 175,000 psi
Product standards require all grade-marked nuts 1/4 inch and larger to have a raised or depressed grade-marking and insignia identifying its manufacturer. The X in the images above represent one location where suck marking may appear.

Stainless Steel, 18-8 and 316, Nut Properties

Description	A six sided internally threaded fastener which is both thicker and wider than a same-sized finished hex nut, made of 18-8 stainless steel. Nuts size 7/16 and smaller shall be double chamfered. Larger sizes are either double chamfered or chamfered on top with a washer faced bearing surface.
Applications & Advantages	The strongest of all the 18-8 nuts because of its greater thread length and greater resistance to dilation (widening or stretching).
Material	Nuts shall be made from one of the following austenitic stainless alloys: 303, 302SE, 304 or XM7, all of which are characterized as having a chromium content of 18% and a nickel content of 8%.
Heat Treatment	The austenitic alloys develop their strength through work hardening during the manufacturing process, as seen from their hardness properties below. The only hjeat treatment normally available on austenitic stainless steel alloys is annealing, which is done at approximately 1900°F to a dead soft condition and is not normally thermally reversible.
Hardness	1/4 thru 5/8: Rockwell B95 - C32 3/4 thru 1 inch: Rockwell B80 - C32
Proof Load	1/4 thru 5/8: 100,000 psi Fine Thread: 85,000 psi
