ASTM A194 Grade 2H Heavy Hex Nut

Featured Heavy Hex Nuts:

ASTM A194 Grade 2H Heavy Hex Nut
The ASTM A194 Grade 2H Heavy Hex Nut is widely considered the workhorse of the industrial fastener world. Designed to be used with class 2A studs or bolts in high-pressure/high-temperature applications, the 2H Heavy Hex Nut represents an economical solution where strength and cost are paramount. The Heavy Hex Nut is made of carbon alloy with a class2B fit. The high carbon content of the Heavy Hex Nut provides for additional strength. While the product is not particularly corrosion resistant, the Heavy Hex Nut may be plated for additional protection against weathering and dilation. The mechanical properties of the 2H Heavy Hex Nut are essentially identical to the DH nut, allowing their direct substitution for each other.

ASTM 453 Grade 660B Heavy Hex Nut
The ASTM 453 Grade 660B Heavy Hex Nut is an ideal solution for extreme service where material creep, sustained corrosion resistance, and strength are imperative. The 660B Heavy Hex Nut is made of premium austenitic steel and precipitation-hardened. The 660B Heavy Hex Nut is an industry favorite for applications in extreme conditions such as those encountered in oceaneering.

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
