Category 8.8/S refers to any bolt of Property Class 8.8, tightened using a standard wrench to a snug-tight condition in the same way as for category 4.6/S. Essentially, these bolts are used as higher grade commercial bolts in order to increase the capacity of certain connection types. In practice they will normally be high-strength

Bolt torque chart reference guides include Grade 2, B7, A307, A325, Grade 8, A490, and Grade 5. AFT Fasteners is your trusted source for fastener information.
Grade 8 Bolts - Coarse and Fine Thread - Grade 8 Nut and 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 Steel Threaded Studs McMaster-CarrGrade 8 steel threaded rods are about 25% stronger than medium-strength steel rods. Zinc yellow-chromate plated steel threaded rods resist corrosion in wet environments. Black-oxide steel threaded rods have a dark surface color and are corrosion resistant in dry environments.

Stainless Steel Nuts, Bolts, Screws, Washers and Fasteners Stainless steel fasteners, bolts, nuts, screws, washers and pop rivets are used to fight corrosion. Contrary to popular belief stainless steel fasteners are not stronger but they do provide superior resistance to rust, staining and corrosion. When looking for fasteners to fight the outdoor elements, especially water, stainless steel nuts, bolts, screws, washers and pop rivets should be your
The two figures indicate the tensile and yield strengths of the bolt or screw. In the case of a 8.8 grade bolt the first figure signifies that the Tensile Strength is at least 800MPa. The second figure signifies that the fastener will begin to yield at 80% of the Ultimate Tensile Strength, i.e. at least 640MPa.
