What Are the Different Grades of Bolts? Hunker

The SAE marking standard starts with grade 2,indicated by a bolt head with no markings whatsoever.A grade 2 bolt made of low-carbon steel has a tensile strength of 64,000 pounds per square inch or less.Tensile strength is the amount of pull the bolt can withstand before breaking.Understanding Fastener Grades and Classes - Fastener MartGrade B Nuts Strength is similar to Grade 5.Grade B7 Threaded Stud Rod Same as Grade 5.Use with Grade 2H and Grade C nuts.Grade C Nuts Strength exceeds Grade 5.Use with heat-treated medium-strength steel fasteners like ASTM A325 structural bolts.Grade G Nuts Strength is similar to Grade 8.Use with ASTM A325 structural bolts.Grade 2 US BOLTS(HEAD MAUS BOLTS(GRADE AUS BOLTS(NOMINAUS BOLTS(MECHANINo MarkingsGrade 2 Low or mediu1/4 thru 3/455,000No MarkingsGrade 2 Low or mediuOver 3/4 thru 1-1/233,0003 Radial LinesGrade 5 Medium carb1/4 thru 185,0003 Radial LinesGrade 5 Medium carbOver 1 thru 1-1/274,000 23 rows on boltdepotBolt Grade Markings and Strength ChartBolt Grade Markings and Strength Chart Mechanical Properties Head Marking Grade and Material Nominal Size Range (inch / mm) Proof Load (psi / MPa) Min.Yield Strength (psi / MPa) Min.Tensile Strength (psi / MPa) US Bolts No Markings Grade 2 Low or medium carbon steel 1/4 thru 3/4

Jan 07,2017 Bolt Grade Markings and Strength Chart#0183;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.The Grade 5 bolt will therefore always fail first whether in tension or shear.The only gotcha with the Grade 8 bolt is that,being harder,it is more notch sensitive.Strength and Grades of Fasteners QuadratecJan 07,2017 Bolt Grade Markings and Strength Chart#0183;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.The Grade 5 bolt will therefore always fail first whether in tension or shear.The only gotcha with the Grade 8 bolt is that,being harder,it is more notch sensitive.Strength Requirements by Grade - Portland BoltAlthough markings are shown on hex heads,stamping is a requirement on one end of rods and studs.The exception is F1554 and A307 grade C in which stamping is a supplemental requirement while color coding is required.Although markings are shown on hex heads,grade markings apply equally to products with other head configurations.
