Hex Flange Bolts Manufacturer in China

Zhenkun offer Hex Flange Bolts in different sizes & standards.Hex Flange Bolts are also available in different materials and grades.Hex Flange Bolts used for construction materials for projects such as docks, bridges, highway systems, and homes, among other things.

Flange bolts

Flange bolts virtually eliminate the need for washers because the area under the bolt head is wider and creates a larger area for even distribution of pressure. We also supply hex flange nuts that work in tandem with our hex flange bolts. We have different grades of hex flange bolts, hex flange nuts, and hex flange screws to fit a wide range of applications.

Non-Serrated Flange Screw

Frame Bolts are hex washer head bolts with a flat washer bearing surface. They are made from high-alloy steel, and commonly used on truck frames, hence the name frame bolt. The flange eliminates the need for washers. They are covered under ASME Standard B18.2.1

Hex Flange Screws are a form of hex head bolt with a wider flange under the head. The circular flange under the head serves as a washer spreading the load and providing nearly four times the bearing area of a regular hex screw. Flange bolts are commonly used in the frames of vehicles, especially trucks. Non-serrated flange bolts are most commonly used.
Common applications of Non-Serrated Flange Screw are:

• • Automotive
• • Plumbing
• • Electronics
