Square-Neck Carriage Bolts made from Grade 8 steel, these bolts are at least 25% stronger than medium-strength steel bolts and can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems.
High-Steel Square-Neck Carriage Bolts Grade 8 | |
Standard: | Square-Neck Carriage Bolts made from Grade 8 steel, these bolts are at least 25% stronger than medium-strength steel bolts and can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. |
Size: | 1/4″ – 3″, Dimensions meet ASME B18.5 specifications |
Material: | Material meets SAE J429,Grade 8: 40Cr, 42CrMo…… |
Grade: | Grade 8 |
Grade 8, Grade 8 steel bolts are marked with six radial lines. | |
Thread: | UNC, UNF, Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration. |
Thread Length: | Partially Thread, Fully Thread |
Finish: | Plain, Zinc Plated (Clear/Blue/Yellow/Black), Black Oxide, Nickel, Hot Dip Galvanized, |
Zinc-plated steel screws resist corrosion in wet environments. Hot-dipped galvanized steel screws are 10 times more corrosion resistant than zinc-plated screws. They have a thicker coating than other finishes; to ensure compatibility, use these screws with hot-dipped galvanized steel nuts. |
