What grade bolt is B7?
Grade B7 is the most common grade of A193 bolts used in construction. B7 threaded studs and short, headed bolts are readily available in the marketplace. Grade B7 bolts are commonly used in pipe flange connections.
Is B7 the same as Grade 5?
B7. This chromium molybdenum steel has similar strength to SAE grade 5 fasteners, however, it is specifically used in high temperature and pressure applications. This grade is for fittings, flanges, valves, and pressure vessels. It is also used as threaded rod in concrete and epoxy.
What is B7 grade steel?
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.
Does B7 have threaded rods?
ASTM A193 Grade B7 fully threaded rods and studs provide high wear resistance, high temperature resistance, and high strength. Made of alloy steel that has been heat treated, they are typically used in high pressure applications, such as valves and pressure vessels in petroleum and chemical equipment.

What are the different grades of bolts?
– SAE Bolt Grades—The standards for bolt strength grades in the U.S. – Metric Bolt Grades—Metric grades are set according to rules set by the ISO (International Standards Organization). – ASTM Bolt Grades—The ASTM grade standard is set by the American Society for Testing and Materials.
What is grade B7?
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.
Can B7 rod be welded?
There are several and each has different properties. In general the materials are weldable, but you might have to follow pre-heat and post-heat procedures to control thermal response. Grade B7 is quenched and tempered, so you might not want to weld on that, depending on your application.
What is Grade A carriage bolt?
Grades 2 and 5, steel, and stainless steel, are the most prevalent types of carriage bolts. Common finishes for Grade 2 are zinc plating and hot dip galvanizing, and zinc plating for Grade 5. Zinc, the most popular and least expensive commercial plating, offers moderate corrosion resistance. Click to see full answer.
