FAQ

What is the difference between Grade 2, Grade 5 and Grade 8?
Grade 2 is low carbon steel with no head markings (74,000 psi minimum tensile in 1/4" to 3/4"). Grade 5 is medium carbon steel, heat treated, with 3 radial lines on the head (120,000 psi). Grade 8 is medium carbon alloy steel, heat treated, with 6 radial lines on the head (150,000 psi). Pair each grade with a nut of the same grade or higher.

What do USS coarse and SAE fine thread mean?
USS (UNC) coarse thread has fewer threads per inch and is the general purpose standard; it assembles fast and is less likely to cross thread. SAE (UNF) fine thread has more threads per inch, which gives a little more strength and finer adjustment, and is common on vehicles and machinery. The nut must match the thread.

How is the length of a hex bolt measured?
From under the head to the end of the bolt. The head is not included.

What finish do these bolts have?
Zinc plating (clear or yellow) resists rust indoors and in dry areas. Plain (black) steel has only a light oil and should be painted or kept dry. For outdoor or wet use, choose hot dip galvanized or stainless steel bolts.
