Industry Trusted Round Head Bolts are very practical for fixing car interiors - for instance, when fixing dashboard components or installing seat brackets. The low-profile round head design allows it to be easily embedded in narrow spaces without interfering with the normal operation of other components.
These bolts are stored in warehouses in the United States and the European Union. So if you place an order from a nearby area, we can ship it on the same day. Usually, delivery takes 2-3 days. Orders over $300 are eligible for free delivery. Large orders (1000 bolts or more) can enjoy a 15% discount.
We pack them in sturdy plastic bags and place them in hard boxes to prevent deformation during transportation. Each box is labeled with operation instructions. We also follow strict automotive industry quality standards: each bolt must undergo rust prevention and torque strength tests. Before shipping, we randomly inspect 10% of each batch of goods to ensure everything is in good condition. In addition, each order comes with a test certificate.

The Industry Trusted Round Head Bolts made of 316 stainless steel are highly suitable for use in the maritime industry - for instance, for securing hardware on the ship deck. They are highly resistant to saltwater erosion and their rounded heads do not allow oysters to attach to them.
For transportation services, we offer sea transportation for larger orders (approximately 10 to 18 days to reach Asia or Europe), and air transportation for faster delivery (3 to 5 days). For orders of 10,000 bolts or more, a 20% discount on sea transportation fees is available.
All the bolts are packed in moisture-proof bags and then placed in waterproof boxes to keep them dry. We test for corrosion by spraying saltwater on them for 500 hours and checking the threads with measuring tools. Each batch of products also undergoes third-party inspection, and we have obtained DNV GL certification, so you know they meet maritime standards.
Q: What is the maximum load capacity of your Industry Trusted Round Head Bolts?
A: As a widely recognized round head bolt in the industry, the weight it can bear needs to be determined in combination with the specific size specifications, selected material and thread type. Taking a 10 mm stainless steel bolt as an example, its typical tensile load-bearing capacity is about 20 kilonewtons. In comparison, the larger 16 mm carbon steel bolt can often withstand tensile forces exceeding 50 kilonewtons.
We have attached data sheets for each type of bolt, which list all the important specification parameters, such as tensile strength, compressive strength and yield strength, etc. Choosing the appropriate bolt for your project is very important - our team can help you select the correct size and type to ensure safety and reliability under load conditions.
