Grades of Bolts - Bolt Grade Marking Chart | AFT Fasteners
This chart helps to identify the grades of bolts using the identification marks on the bolt's head along with the strength and hardness of common grade bolts. Please note the bolt heads may also include the manufacturer's identification stamp, especially with high strength bolts. Grade 8 - SAE J429. Grade 8.2 - SAE J429.
Bolt Grade Markings and Strength Chart
Tensile Strength: The maximum load in tension (pulling apart) which a material can withstand before breaking or fracturing. Yield Strength: The maximum load at which a material exhibits a specific permanent deformation.
Grade 8 Bolts: Strength & Applications - Wilson-Garner
2023年8月2日 · Grade 8 bolts are made of medium-strength carbon or alloy steel and can be finished in a variety of coatings and platings for added corrosion resistance and lubricity. You can identify a Grade 8 bolt by looking at its head markings. An SAE J429 Grade 8 bolt’s head marking will show six radial lines like this:
