Structural Integrity Stud Bolts

Structural Integrity Stud Bolts are widely used in heavy machinery because they perform well under high pressure and effectively ensure the structural stability of such equipment. Both ends of the screws are threaded rods that can effectively fix components together. We offer screws of different sizes, with specifications ranging from 1/4 inch to 2 inches. You can also choose the appropriate length as per your needs.

We will ship promptly with reliable partners, so domestic orders usually arrive within 2-3 days. The shipping cost depends on the quantity you order and the destination of the goods. Each screw is packed in a sturdy metal box, which is filled with foam to prevent damage. All items are wrapped in plastic to prevent water ingress.

We perform special tests on each batch of products to accurately verify the thread size accuracy and screw tightening performance to ensure that core indicators meet the standards. For each batch of products, we will carry out a rigorous testing process to confirm whether the thread accuracy is compliant and whether the screw firmness meets the use requirements.

Product Benefits

In the oil and gas industry, Structural Integrity Stud Bolts play a crucial role in ensuring a tight seal between flanges and pipes. The product's performance remains excellent even in high-temperature and chemical conditions; the thread structure supports precise tightening operations and reliably prevents leakage problems.

Our bolts are treated with galvanization to prevent corrosion. However, if you require a more robust material, we also offer bolts with hot-dip galvanization. Due to the strict time requirements in this field, we provide a fast delivery service - urgent orders can be delivered within 48 hours. For large orders exceeding 500 pieces, we also offer a 15% discount on shipping costs.

We pack them in sealed steel drums, which have waterproof and impact-resistant properties. Therefore, even if the transportation process is quite intense, they can be protected. Each bolt undergoes ultrasonic testing, and we have obtained API 5L certification, so you know they meet industry standards.

Material grades and certifications

We have different grades of Structural Integrity Stud Bolts: ASTM A193 B7, B8, L7, and A320 L7. We can trace the origin of all materials and provide factory test certificates (MTCs) that comply with the EN 10204 3.1 standard. These certificates ensure that the bolts meet international standards for pressure vessels and valves, making them both reliable and safe.
