Heavy Duty Stud Bolts

In construction projects, Heavy Duty Stud Bolts are often used for steel structure connections because they can provide a more secure fixation to components than ordinary bolts. Due to the common hexagonal head shape, this type of bolt can be easily tightened with a wrench. Their lengths range from 6 inches to 3 feet.

We can deliver the goods in different ways: for larger orders, we offer land transportation service (delivered within 3-5 days); if urgent delivery is needed, we provide air transportation service (arrives the next day). For orders over $10,000, we offer free delivery service, which helps save costs. The goods will be placed on sturdy wooden pallets and tightly wrapped with plastic film - this ensures that the goods are dry and safe even if stored outdoors for a period of time.

We will also conduct hardness and size tests on each batch of products. All our bolts comply with the ASTM A325 standard. In addition, if any defects occur in the products, we also offer a 5-year warranty service.

Product Details

In automotive manufacturing, Heavy Duty Stud Bolts are widely used during the engine assembly process because they are very sturdy (with a strength of up to 12.9 grade) and do not tend to loosen due to vibration. They have fine threads, which helps you tighten them to the exact position, and usually come with a black oxide coating to prevent rust.

We adopt a shipping method that can adapt to the tight production schedule - if you place an order before 10 a.m., we can deliver it on the same day, and you will receive the goods within two days. Our reliable transportation partners will provide services for you. The freight is calculated based on the weight per kilogram, and old customers can enjoy a 10% freight discount.

They are packed in anti-static bags and placed in cardboard boxes to prevent them from being scratched or dirtied. We also use magnetic detection tools to check each bolt to detect any potential cracks. Our factory has obtained TS 16949 certification, so it fully complies with the quality standards of the automotive industry.

Comply with international standards

Our Heavy Duty Stud Bolts fully comply with all major international standards. For instance, in terms of materials, they follow the ASTM A193/A320 standard, and in terms of dimensions, they adhere to the ASME B16.5 standard. Simply put, these things are very convenient to use with other components, and can meet the requirements of any country's engineering standards. Therefore, installation is very straightforward and there are no complications at all.
