Grade 8 bolts are manufactured in different materials, thread types, lengths, coatings, and classes of fit, so it is critical that all those factors are taken into account when choosing the type of Grade 8 bolt is best.Fasteners | Bolt Grades, Strength & MaterialsThese letters that you're seeing is the manufacturer's markings, so they can identify, should the bolt fail, they can identify if this is their bolt or not. So typically grade eight, in most cases, is coated in yellow zinc. You can see this bolt, it's coated with a yellow zinc.
USA Grade 8 bolts are alloy and are stronger than grade 5 bolts. They are used in demanding applications.

To take full advantage of strength properties the shank of the bolt body should be within the shear planes. To illustrate, consider the difference in shear strength between the two Grade 8 bolts
Grade 5 bolts have 3 evenly spaced radial lines on the head. Grade F is roughly equivalent to Grade 5. Grade F nuts are used with Grade 5 bolts. Grade 8 / Grade G. Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions.Bolt Depot - Bolt Grade Markings and Strength Chart23 rows · Grade 8 Medium carbon alloy steel, quenched and tempered: 1/4" thru 1-1/2" 120,000: No MarkingsGrade 2 Low or mediu1/4" thru 3/4"55,000No MarkingsGrade 2 Low or mediuOver 3/4" thru 1-1/2"33,0003 Radial LinesGrade 5 Medium carb1/4" thru 1"85,0003 Radial LinesGrade 5 Medium carbOver 1" thru 1-1/2"74,000See all 23 rows on www.boltdepot grade 8 bolt hardness material equivalentB7 vs. Grade 8 - All America Threaded ProductsJun 17, 2020 · Grade 8 (SAE J429) is a medium carbon alloy steel with one of the highest tensile strengths grade 8 bolt hardness material equivalent
Jun 08, 2018 · However, as you can see in the following table, both tension and shear are higher in Grade 8 bolts over Grade 5 bolts; in fact over 21% higher in shear and 25% in tension. The same is true in metric when comparing 8.8 vs 10.9. To be fair, the higher the grade of bolt, the harder it becomes as rated by the rockwell scale.Alloy Steel Grade 4140 | Elgin FastenersAISI 4140 Steel, normalized at 870°C (1600°F), air cooled, 25 mm (1 in.) round.
