HDG U bolt
U-bolts are called U-bolts in English. They have threads at both ends and can be combined with nuts. This type of bolt has a wide range of applications and is often used to fix tubular objects (such as water pipes) and sheet objects (such as automobiles). According to the length of the thread, U-shaped bolts are divided into two categories: full thread and non-full thread. According to the thread profile, U-shaped bolts are divided into coarse threads and fine threads. According to the performance of the bolts, U-shaped bolts are divided into eight grades: 3.6, 4.8, 5.6, 5.8, 8.8, 9.8, 10.9, and 12.9. Among them, U-shaped bolts with grade 8.8 or above (including grade 8.8) are made through heat treatment processes such as quenching and tempering. Their raw materials are low-carbon alloy steel or medium-carbon steel, and are called high-strength bolts. U-shaped bolts below grade 8.8 (excluding grade 8.8) are called ordinary bolts.
