A Guide to Bolts and Bolt Tensile StrengthNov 19,2020 a % of bolt yield#0183;Steel bolts are graded according to newtons per millimeter squared for bolt tensile strength as compared to yield strength.For example,a steel bolt with a rating of 5.5 will provide roughly 500 newtons/mm2 of bolt tensile strength and approximately 400 newtons/mm2 of yield strength.What is Proof Load of a Bolt and How is it Different from The yield strength of a bolt can be defined as the tensile force that will produce a certain amount of permanent deformation within a specific fastener.In many (but not all) bolting situations,its important not to tension a bolt past its yield strength,because it no longer retains its original size and shape and ultimately its performance

The tensile strength of a grade 8 bolt is 150,000 pounds per square inch.Tensile strength is the maximum load in tension (stretching) that a part can carry without breaking.In addition to tensile strength,other mechanical factors in a connection should be considered,including yieldUS 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 boltdepota % of bolt yield.- WOODCO USABolt Yield Strength psi Enter bolt material Yield Strength in psi.(Use no comma) Enter 105000 for B7/L7 standard bolting.(Enter 95000 for B7 bolts larger than 2.5) (Enter 80000 for B7M/L7M Modified bolting up to 4) Percent Yield Enter percent of bolt Yield Strength.50% specified byTorque to Yield Bolts - FreeASEStudyGuidesTorque to Yield Bolts.With a standard bolt,a technician could torque the bolt to its yield point,and it would return to its original form and length when removed.It has elasticity; it can stretch and then return to its original form.This is not so with torque to yield bolts.

At the yield point,the force becomes strong enough that the steel will stretch and not return to its original shape.This amount of force is the yield strength.To test yield strength in our example,you would put our a % of bolt yield#189;-13 bolt into the tensile machine,stretch the part until it distends,and calculate the force at the point of yield.People also askWhat is Grade 5 bolt strength?What is Grade 5 bolt strength?They have a tensile strength of 60,000 PSI.Grade 5 bolts are a heat treated carbon bolt.Hardened to increase its strength,its most commonly found in automotive applications.Grade 5 bolts have 3 evenly spaced radial linesresembling an airplane propeller.WHAT GRADE OF BOLT SHOULD I USE?
