With that said, A193 bolts can be ordered with UNC threads if that is specified when they are ordered. If a thread pitch is not specified, most fastener suppliers/manufacturers will supply this grade of bolt (A193 grade B7) with 8 threads per inch on bolts above 1″ in diameter. Most good suppliers will ask what thread pitch the …
Grade B6 is a heat-treated 12% chromium-ferritic magnetic 410 stainless steel with minimum tensile strength requirement of 110 ksi and yield 85 ksi. ASTM A193 specification covers requirements for chemical composition, mechanical properties, hardness, heat-treatment and recommended nuts-washers for Grade B6 Fasteners.

A194 2H nuts are a common high strength nut used with many different bolt grades, including A193 Grade B7, A325, A490, F1554 Grade 105 and others. Occasionally Portland Bolt will be asked to provide A194 Grade 2HM nuts, most often with A193 Grade B7M. In many grades an 'M' refers to metric, which is not the case here.

Since A193 Grade B7 has a maximum hardness requirement of Rockwell C35, it is highly unlikely that the tensile strength for a given lot would exceed 150 ksi. The other concern is the effect that the heat of the molten zinc might have on the strength of the A193 Grade B7 bolts. When quenched and tempered bolts are heated to within 100 …

Chemical analysis of finished products manufactured to ASTM A193 Grade B7 specification must comply with below requirement. This typical composition is in line with the AISI 4140 / AISI 4142 alloy steel used as a raw material to produce B7 bolts, studs and other external threaded fasteners.
ASTM A193 defines both SI (Metric) and inch-pound units. Grade B7 is a heat-treated chromium-molybdenum low-alloy steel with minimum tensile strength requirement of 125 ksi (860 Mpa), yield 105 ksi (720 Mpa), and maximum hardness of 35HRC. Boltport uses Alloy Steel AISI 4140 bar stock or forging stock to produce B7 headed and non-headed bolts.
B7 Heavy Hex Bolt. ASTM A193 Grade B7 heavy hex head bolts are high strength fasteners manufactured from heat treated alloy steel AISI 4140/4142, quenched and tempered. Dimensional specifications are governed by ASME B18.2.1. Grade markings consists of both the grade symbol "B7" and the manufacturer's identification mark.
Because of their application, A325 bolts must always have a forged head in order to meet the specification. These bolts can be manufactured in diameters 1/2″ through 1-1/2" in diameter. A193 bolts are designed for high-pressure, high-temperature applications. They are commonly found on pressure vessels and pipe valves.
ASTM A193 GR. B7. ASTM A193 Grade B7 is a specification that defines the requirements for high-strength alloy steel bolting materials. It is one of the most commonly used grades in the A193 standard due to its excellent mechanical properties and suitability for high-temperature and high-pressure applications.
This table shows the mechanical properties of B7, Grade 5 and Grade 8: GRADE GRADE 5 ASTM A193 B7 (Chromium Molybdenum) GRADE 8 (Heat Treated After Threading) TENSILE STRENGTH 120,000 PSI minimum 125,000 PSI minimum 1,100°F tempering temp 150,000 PSI minimum YIELD STRENGTH 92,000 PSI minimum …
Metric Medium-Strength SteelThreaded Rods—Grade B7. Made of Grade B7 steel, the tensile strength of these threaded rods is one and a half times higher than low-strength steel threaded rods. They also meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.
