Understanding Fastener Grades and Classes - Fastener Mart

SAE Grade 8 Screws are marked on the top of their heads, the exceptions being small (under about 1/4"), slotted and recessed head fasteners where there is insufficient room for head markings. A head with no markings is Grade 2, one with 3 lines spaced 120 degrees is Grade 5, and 6 lines spaced at 60 degree intervals is Grade 8.Strength Requirements by GradesStrength Requirements by Grades. Yield strength, or working load limit, is the amount of stress a material can withstand without permanent deformation.. Tensile strength is the maximum amount of axial stress that a material can take before breaking.. All strength measurements are in ksi (kilo-pound per square inch). To find the actual weight a bolt can withstand you would have to multiply by grade 8 steelStrength Requirements by GradesGrade Material Size Range Yield (ksi) Tensile (ksi) Hardness; Grade 2: Carbon Steel: 1/4 - 3/4 (7/8 - 1 1/2) 57 (36) 74 (60) B80-B100: Grade 5: Carbon Steel: 1/4 - 1 (1 1/8 - 1 1/2) 92 (81) 120 (105) C25-C34: Grade 8: Alloy Steel: 1/4 - 1 1/2: 130: 150: C33-C39: Sockets: Alloy Steel: 1/2 (1/2 -
