Product Description

From the very beginning, we conducted a thorough inspection of the Streamlined Hexalobular Head Flange Bolts. First of all, the raw materials we use (high carbon steel or alloy steel) strictly comply with mainstream industry standards such as ASTM and ISO.

During the production process, the machine will check the manufacturing accuracy of the coil, flange and head. To ensure that the samples can withstand torsional strength, we conduct regular tests. Each batch of products is carefully inspected by hand to promptly detect potential defects such as cracks and uneven coating.

This type of detailed inspection can effectively ensure the reliable operation of each bolt and is particularly important in critical application scenarios.

Product Details

Before leaving the factory, every Streamlined Hexalobular Head Flange Bolts undergoes a comprehensive quality inspection. We use precise tools to check the threads to ensure the flange is flat and to inspect whether the drive system is intact. From each batch of products, we randomly select samples for strength tests (such as how much lateral force they can withstand) and corrosion tests, including salt spray tests.

Any Unqualified bolts will be removed. Only bolts that fully meet all standards will be shipped. This meticulous inspection carried out before delivery means you can be assured that these bolts will work reliably and the possibility of failure during use will be lower.

FAQ

Q: How do Streamlined Hexalobular Head Flange Bolts resist corrosion, and what coatings are available?

A:The corrosion of Streamlined Hexalobular Head Flange Bolts mainly depends on their material or the coatings added. Stainless steel type bolts can naturally resist rust due to the presence of chromium. Carbon steel bolts usually require coatings such as galvanization, tin plating or epoxy resin. Galvanization provides good protection in dry or indoor environments, while hot-dip galvanization offers stronger protection in outdoor or humid conditions. For extremely harsh environments such as marine or chemical environments, special coatings like xylan or Dacromet can be used to resist the erosion of salt water and chemical substances.
