Engineered Excellence Headed Studs

Engineered Excellence Headed Studs are widely used in construction to connect steel beams and concrete slabs. They have a cylindrical body and a welded head, providing a stable fixation. The price is competitive. Orders over 500 kilograms can enjoy a 5% discount. We ship via courier companies - the delivery time is 2 to 3 days - or by standard transportation method, which is cheaper but takes 5 to 7 days. All bolts are packed in steel boxes with waterproof padding to prevent moisture. We conduct quality inspections, including material checks (the tensile strength must be at least 600 megapascals) and size checks. Each batch of products comes with a CE certificate and is tested three times before leaving the factory to ensure there are no defects. Head bolts are the ideal choice for structural engineering.

Product Details

In automotive manufacturing, Engineered Excellence Headed Studs are used to secure the chassis components together. These bolts are of relatively small size - typically ranging from 10 to 50 millimeters in length - and can be easily installed in narrow spaces. They are reasonably priced and, when you order 1000 or more pieces, you can enjoy an 8% discount. We ship by truck; this is an economical and efficient option, and deliveries are approximately 3 to 4 days. The bolts are packaged in foam-lined plastic trays to prevent scratches, and we also use waterproof bags for additional protection. We follow ISO 9001 for quality control, and each bolt undergoes a hardness test (HV 200 - 250). Our products have obtained IATF 16949 certification, thus meeting industry standards. The countersunk bolts are of high precision and help make vehicles sturdy and reliable - that's why many large automotive manufacturers use them.

Main Materials

Our Engineered Excellence Headed Studs are mainly made of carbon steel, stainless steel (such as grades 304 and 316), and alloy steel (such as A193 B7).

In high-temperature environments, alloy steel bolts perform well - they can be used at temperatures up to 650°C without deteriorating. Stainless steel has excellent high-temperature oxidation resistance and is therefore often used in high-temperature working conditions such as furnaces and exhaust systems.

All materials undergo heat treatment to make them more durable. This helps the bolts remain strong at extreme temperatures. Each batch of products comes with a material certificate so that you can know exactly where it comes from.
