15 rows Grade B Nuts : Strength is similar to Grade 5. Grade B7 Threaded Stud Rod: Same as Grade 5. Use with Grade 2H and Grade C nuts . Grade C Nuts : Strength exceeds Grade 5. Use with heat-treated medium-strength steel fasteners like ASTM A325 structural bolts . Grade G Nuts : Strength is similar to Grade 8 . Use with ASTM A325 structural bolts . Machined Brass Fasteners (Screws, nuts , bolts , etc.) are made from alloy 360 brass, and non-machined parts like washers are made from alloy 270 brass. Grade C , Grade 2, Grade 5 and Grade 8 . Untreated alloy steel fasteners are black. Titanium. A metric bolt designated as ISO class 6. 8 roughly corresponds in strength to an SAE Grade 2 bolt. Bolts of ISO class 8 . 8 and the slightly stronger class 9. 8 roughly correspond to an SAE Grade 5 bolt. An ISO Class 10.9 bolt roughly corresponds to an SAE Grade 8 bolt.
