Plain A354 Grade 8 Heavy Hex Bolt
The bolt performance of steel structure connection is divided into 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 and other more than 10 grades. Among them, the bolts of grade 8.8 and above are made of low carbon alloy steel or medium carbon steel, and after heat treatment (quenching and tempering), they are generally referred to as high-strength bolts, while the rest are generally referred to as plain bolts.

| A354 Grades | |
| BD | Higher in strength than A354 grade BC and equal in strength to ASTM A490 bolts. The A354 BD specification has no restrictions on configuration. A354 BD should be considered for anchor bolts, threaded rods, other styles of headed bolts, and bolts larger than 1-1/2″ diameter where properties similar to A490 are needed. A354 grade BD does not require a magnetic particle test. |
| BC | Lower in strength than grade BD |
