The nut material for Grade B7 bolts is typically ASTM A194 heavy hex nuts (2H nuts). This is supposed to be a stack of B7s on a job site.Bolt Depot - Selecting Fastener Materials - Steel Grades Fasteners Bolt Grades Strength MaterialsFasteners are manufactured in a wide range of materials from common steel to titanium, plastic and other exotic materials. Many materials are further separated into different grades to describe specific alloy mixtures, hardening processes, etc. In addition, some materials are available with a variety of coatings or platings to enhance the corrosion resistance or alter the appearance of the fastener.Bolt Gradesdefined as failure at stresses apparently below the strength of the bolt material with little or no evidence of plastic deformation. Typically, fasteners are not brittle below 180 ksi ultimate tensile strength. Grade 5s have an ultimate tensile strength of 120 ksi and a grade 8 fastener has an ultimate tensile strength

Grade B16. ASTM A193 Grade B16 bolts and threaded studs are manufactured from a chromium-molybdenum-vanadium alloy steel. Although A193 Grade B16 bolts and studs have similar strength requirements as Grade B7, the vanadium and higher tempering temperature helps the fasteners retain their molecular structure and strength under higher ambient temperatures than Grade B7.Grades - ASTM A320A320 Grade B8M bolts also do not require an impact test. Grade L43. ASTM A320 Grade L43 bolts and threaded studs are manufactured from AISI 4340 material and are also quenched and tempered.

Yield strength, or working load limit, is the amount of stress a material can withstand without permanent deformation.. Tensile strength is the maximum amount of axial stress that a material can take before breaking.. All strength measurements are in ksi (kilo-pound per square inch). To find the actual weight a bolt can withstand you would have to multiply by Fasteners Bolt Grades Strength Materials
Jan 07, 2017There exists an often quoted myth, that Grade 5 bolts are better in shear than Grade 8 since they will bend before breaking. Not true. Shear strength of alloy steel is approximately 60% of its ultimate tensile strength. Reference to Table 1 shows that the yield strength of a Grade 8 bolt is higher than the ultimate strength of a Grade 5 bolt.Stud Bolt - A complete Guide of Pipe FastenersAlloy steel quenched and tempered studs and bolts material grades are ASTM A354 Gr BC, BD.
