Grade 8 bolt. 4.6 Low or medium carbon steel M1.6 - M39 225 240 400 (58,000 PSI) B67 B95 8.8 … 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. Bolts Screws Pins Washers Nuts … A grade 8 bolt is stronger than the more commonly used grade 5. Home | Size / Thread Reference. Socket Head Cap Screws made from alloy steel are typically manufactured to a higher strength than SAE Grade 8: 180 ksi tensile strength for fasteners up to 1/2 inch, 170 ksi for larger sizes … ASTM A193 Grade B16 bolts and threaded studs are manufactured from a chromium-molybdenum-vanadium alloy steel. Max. Grade 8 bolts have a tensile strength of 150,000 pounds per square inch. Head Markings Metric Bolt Class Mechanical Properties Proof Load (MPa) Min Yield (MPa) Min Tensile Strength (MPa) Class 8.8 Medium carbon steel, quenched and tempered 580-600 640-660 800-830 Class 10.9 Alloy Steel, quenched and tempered 830 940 1040 Class 12.9 Alloy Steel, quenched and tempered 970 1100 1220 A2 Stainless Also called 18-8 … ... (80) percent of yield strength … 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 … Examples of hardened fasteners are steel bolts - US Grade 8 (Metric property class 10.9), hardened steel washers, spring washers, etc. Grade Marking Specification Material and Treatment Nominal Size (In.) A grade … Gr 8 bolt capability in yield (stretch) = 130,000 lbs / in2 x .03349 in2 = 4354 lbs minimum High tensile Grade 8 bolt capability in tension (failure) = 150,000 lbs / in2 x .03349 in2 = 5024 lbs minimum Grade 8 hex bolts have 6 marks on the head. You can look that up to go over on google. Proof Strength (MPa) Min. Just google that and you'll find all the information in reference to the treatment of a grade 8 bolt. Tensile (MPa) Grade Identification Marking Min. Both of these yield strengths are … It is made of alloy steel and has six radial lines on the top of the bolt head. In many (but not all) bolting situations, it’s important not to tension a bolt past its yield strength… Grade B16. So, with a grade 8, this falls under the SAE J429. We recommend using grade 8 nuts, flat washers and high alloy lock washers with any grade 8 bolts … Tensile Strenght: Proof Load Tensile Strength for Grade 2, 5, & 8, ... Alma Bolt Company & Prime Fasteners 1-800-526-2200. To put all of this into context, your typical grade 5 bolt has a tensile strength of around 120,000 psi, and a grade 8 is in the 150,000 psi range.
