Grade 8 Standard Specification for Carbon and Alloy Steel Nuts for Bolts for High Pressure or High Temperature Service, or both. ASTM A194 specification covers a variety of carbon, alloy, and martensitic stainless steel nuts in the size range 1/4 through 4 in. and metric M6 through M100 nominal.
ASTM, SAE and ISO Grade Markings for Steel Fasteners Hardnesses are Brinell Hardness Numbers. The nut manufacturer, at his option, may add other markings to indicate the use of atmospheric corrosion resistant steel. Specifications ASTM A563 Carbon and Alloy Steel Nuts. ASTM A194/A194M Carbon and Alloy Steel Nuts for Bolts for High Pressure and High Temperature Service.

EN Class 8.8 EN ISO 898-1 - BBN STEEL STORESEN Class 8.8 EN ISO 898-1 mechanical. Introduction of mechanical properties EN Class 8.8 EN ISO 898-1 Yield points When the stress of EN Class 8.8 EN ISO 898-1 or specimen exceeds the elastic limit in tension, even if the stress does not increase, the EN Class 8.8 EN ISO 898-1 or specimen will continue to undergo obvious plastic deformation.

A grade 8 bolt is stronger than the more commonly used grade 5. It is made of alloy steel and has six radial lines on the top of the bolt head. Grade 8 bolts have a tensile strength of 150,000 pounds per square inch. We recommend using grade 8 nuts, flat washers and high alloy lock washers with any grade 8 bolts / hex cap screws.
Grade 8 Bolts - Lightning Bolt & SupplyGrade 8 typically has a core Rockwell hardness of C33-C39, while Grade 5 have a core Rockwell hardness of C25-C34. 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.
