What is Heavy Hex Nuts

1. What is Heavy Hex Nuts? The heavy Hex Nuts, also referred to as structural nuts are both wider and more thick than the typical (finished) hexagon nut. They are compatible with strong and bolts with large diameters. Nuts of sizes 7/16" and less can be double chamfered. Nuts that are larger over 7/16" are double chamfered or chamfered over the top of a washer facing bearing surface. They are used most often in engineering and construction applications and are often paired with the heavy Hex (structural) bolts. The Heavy Hex Nuts Grades are: Grad A Hex Heavy Nuts Grade A Hex nuts are used in conjunction with the low-carbon heavy Hex Bolts. They are made of steel and have the following chemical compositions Carbon: 0.55% max; Phosphorus: 0.12% max; Sulfur: 0.023% max. Grade A Nuts are made with an average Core hardness that is Rockwell B68-C32. Fasteners Manufacturers in India Grade C Heavy Hex Nuts Grade C Nuts are suggested to be used in conjunction with structural bolts of A-325. They are made of steel that has the following chemical compositions Carbon: 0.55% max; Phosphorus: 0.12% max; Sulfur: 0.023% max. Grade C Nuts are characterized by the Core hardness that is Rockwell B78-C38. A 194 Grade 2H Hex Nuts Heavy Grade 2H bolts are suggested for bolts used in high-temperature or high- pressure applications. They are made of steel that has the following chemical compositions Carbon: 0.4% min; Manganese: 1.0% max; Phosphorus: 0.04% max; Sulfur: 0.05% max; Silicon: 0.40% max. Grade 2H nuts are treated with heat and have a core hardness at Rockwell C24-C38. 563 Grade Heavy Hex Nuts Grade DH Nuts are suggested to be used with A-490 type 1 bolts for structural use. They are made of steel that has the following chemical compositions Carbon: 0.20-0.55% min; Manganese: .60% min; Phosphorus: 0.04% max; Sulfur: 0.05% max. Grade DH Nuts are treated with heat and have a core hardness that is Rockwell C24-C38. The 563 grade DH3 heavy Hex Nuts +91 83690 74984 | sales@anankafasteners.com | https://anankafasteners.com/

2. Grade DH 3 Nuts are intended for use with A-490 type 3 bolts for structural use. Grade DH3 Nuts have been heat treated and have the Core Hardness in the range of Rockwell C24-C38. What is the main difference between a normal Hex nut and a heavier Hex nuts? A standard hex-nut, sometimes referred to as a finished hex-nut has a narrower width across the corners and flats when compared to a heavier Hex nut. A heavy hex nut is larger than a standard nuts that is the same size. In actuality the heavy hex nut is exactly one-eighth" greater across the flats than a typical Hex nut of all sizes and require an 1/8" larger wrench or socket to put in. Additionally, heavy hex nuts are stronger in capacity to withstand load when compared to an hex nut, as per ASTM A563. Stud Bolts and Nuts What exactly is a standard Hex Nut? A normal hex nut, or a finished hex nuts is distinct from a heavier Hex nuts. The primary difference is to be with the narrower dimensions. It's evident across flats and the corners. A stronger nut coupled with bolts that are weaker won't cause any problems, but the weaker nut coupled with a stronger bolt is likely to result in a fastener failing. What is an heavy Hex Nut? A hex nut that is heavy is thicker and more heavy in weight. The nut has a bigger size across the flats. They also require bigger wrenches and sockets to be fitted. The strength of the load is greater than that of a standard Hex nut, which means it is able to support more weight quickly. +91 83690 74984 | sales@anankafasteners.com | https://anankafasteners.com/
