B7 studs have very high tensile strength and are generally\nused in high pressure \u0026amp; temperature environment like petroleum or chemical\nindustry for flanges. It is generally coupled with GRADE 2H NUTS. ... Note: B7\nstuds are very similar to B16Stud Bolts ASTM 193 with the absence of Vanadium.\nB7 Threaded Rod. These rods are made from a Chromium Molybdenum alloy steel\nand are heat treated to a tensile strength of 125,000 psi minimum and a\n105,000 psi yield strength. They are used for bolting flanges, valves, and\nother maintenance applications where strength is important. Blue PTFE\npossesses a low coefficient of friction which reduces torque requirements.\nFluoropolymer metal coatings advantages include extreme durability and low\nwear. However, during assembly of fasteners in the field, the coating can\nsometimes be damaged. With most other fluoropolymer coatings, this results in\nexposed bare metal that quickly begins to show corrosion and causes the\ncoating to fail. Our metallic base coat ensures superior corrosion resistance\nand continues to provide protection even under the harshest conditions. Lamons\nensures the highest quality control of all orders, big or small. Each order\nfastener is checked for cure, thickness, adhesion and overall coverage.\nConcentrations and temperatures of all solutions and chemicals used in the\nprocess are strictly controlled and written records are maintained. Our\nadvanced, computer controlled, automated equipment keeps the coating thickness\nprecise and extremely uniform. Great care is taken during the process so that\nfasteners with a specified minimum hardness of Rockwell C32 or higher are not\nexposed to the absorption and entrapment of hydrogen which can cause hydrogen\nembrittlement failure. Why are studs stronger than bolts? Studs provide the\nability to obtain much more accurate torque values because the studs don't\ntwist during tightening as do bolts. Because the studs remain stationary\nduring nut tightening, the studs stretch in one axis alone, providing much\nmore even and accurate clamping forces. 2H Heavy Hex (2H HH) nuts are a common\nhigh strength nut used with many different stud grades, including A193 Grade\nB7, A325, A490, F1554 Grade 105 and others. Heavy hex nuts are slightly larger\nand thicker than standard (finished) hex nuts. There are numerous grades and\nthe heavy pattern is typically used for large diameter and high strength\nbolts. This extra-wide, extra-thick hex nut features increased bearing surface\nand thread engagement for improved hold.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul
