Stainless Steel Carriage Bolts

Our company, a major player in the fastener field, manufactures a wide variety of bolts. Standard bolts are our staple products. We offer hex bolts in diverse grades. Mild - steel ones are great for everyday use, while high - strength alloy steel versions are perfect for heavy - duty tasks. They're available in both metric and imperial sizes, with lengths varying from short to long. Carriage bolts, recognized by their round heads and square necks, are popular for wood - related projects as they prevent rotation. We also produce specialty bolts. Anchor bolts, crucial for attaching structures to concrete, come in wedge - type, headed, and expansion styles. They can endure high forces, ensuring the stability of large - scale constructions. Socket head cap screws, featuring smooth, low - profile heads, are widely used in precision machinery and automotive engines for a neat look. In terms of materials, we have stainless - steel bolts that resist corrosion, suitable for marine and food - processing settings. Aluminum bolts, being lightweight yet strong, are favored in aerospace and automotive industries where weight reduction matters.

Our minimum order quantity (MOQ) varies depending on the bolt type. For standard hex bolts, the MOQ is typically 1,000 pieces per size. This helps us streamline production and cover associated costs. For specialty bolts like custom - designed anchor bolts, the MOQ is around 5,000 pieces due to the complexity of manufacturing. However, we're flexible. If you're ordering a diverse range of bolts, we can negotiate a lower MOQ for each item. For new customers looking to build a long - term relationship, we'll consider reducing the MOQ on a case - by - case basis. For common aluminum bolts, we may set the MOQ as low as 800 pieces to accommodate smaller - scale projects.

Here are the key points for choosing the right bolt size. First, consider the application. For light - duty applications like furniture assembly, small - diameter bolts such as M4 or M6 are usually sufficient. In contrast, for heavy - duty machinery or structural connections, larger bolts like M12 or M16 might be required. Second, check the thickness of the materials to be joined. The bolt should be long enough to pass through all the components and allow for proper threading. As a general rule, the bolt length should be about 1.5 times the thickness of the materials. Finally, take into account the available space. If the installation space is limited, you may need to choose a shorter or thinner bolt to fit. In some cases, you might also need to consider the bolt's head type and drive style to ensure it can be properly installed and tightened.
