Streamlined Round Head Bolts

These heavy Streamlined Round Head Bolts (rated at 12.9) are specifically designed for mining equipment (such as tunnel support structures). They are made of extremely strong alloy steel and can withstand high pressure. Their circular head design helps to avoid damage caused by falling rocks.

We transport the goods to remote mining sites by off-road transportation, which usually takes 7 to 10 days. For urgent needs, we can complete rapid delivery within 4 to 5 days. Order 10,000 or more bolts and receive 30% off shipping.

These bolts are packed in sturdy wooden boxes and are coated with a thick anti-rust layer. We will test them to ensure they can withstand heavy loads and work normally in cold conditions. Each batch of products will be inspected to meet the DIN 931 standard and obtain ISO 14001 certification. If any bolts are damaged during transportation, we will replace them.

Product Details

Streamlined Round Head Bolts are very common in bicycles - they are used to fix components such as the frame and handlebars. These bolts are usually made of lightweight aluminum or titanium and come in different colors such as black, silver or bright neon colors.

For orders of smaller quantities (less than 100 bolts), we ship by express delivery, which takes 2 to 3 days and costs between $5 and $12. For larger orders, we use standard delivery (5 to 7 days, costs between $10 and $25). Orders over $300 are free of charge. In addition, we provide samples for you to try before purchasing.

These bolts are packed in small boxes and sorted by size and color. We test each batch of bolts to ensure the threads are accurate and do not loosen under pressure. They also undergo fatigue tests to simulate driving conditions. All bolts comply with the safety standards of the U.S. Consumer Product Safety Commission and come with warranty terms covering any manufacturing defects.

FAQ

Q: How are Streamlined Round Head Bolts packaged for international shipping to prevent damage?

A: To ensure that our Streamlined Round Head Bolts arrive in perfect condition, we pack them in sturdy cardboard boxes or metal cases. Smaller orders are sealed in plastic bags to prevent moisture damage.

During work, we first complete the classification according to the size of the bolts; if necessary, we will also apply anti-rust oil to the bolts to provide dual protection against scratches and corrosion. For large orders, we will stack the cargo boxes neatly on the pallet and then wrap them tightly with packaging materials to fully ensure the safety of all items during transportation and handling. Each package is clearly marked with product details, quantity, and any special handling instructions.

In this way, the bolts can be delivered intact and put into use immediately.
