Our Zinc Plated Hex Flange Self Tapping Construction Bolt is designed for efficient fastening in construction, metal fabrication, machinery assembly, and industrial installation projects. Featuring a hex flange head design and self-tapping thread structure, this bolt provides strong holding force, easy installation, and reliable fastening performance.
The zinc plated surface treatment improves corrosion resistance and extends service life in various working environments. This Hex Flange Self Tapping Bolt is widely used for fixing metal sheets, steel structures, equipment components, and construction materials.
As a professional Fastener Manufacturer, we supply a complete range of fastening solutions, including bolts, screws, nuts, washers, expansion anchors, and customized Industrial Fasteners for global distributors and OEM customers.
Hex Flange Head Self Tapping Bolt is a durable industrial Bolt engineered for fast and secure fastening without pre-threaded holes. The integrated flange head distributes clamping force evenly, improving holding performance while reducing the risk of material deformation.
Manufactured from high-quality carbon steel or stainless steel, these self tapping bolts are available with zinc plated, hot dip galvanized, Dacromet, or plain finishes to suit indoor and outdoor applications. Precision thread forming ensures excellent penetration, reliable fastening, and long service life in demanding environments.
Designed for wholesale distribution, OEM manufacturing, and export projects, this product is widely used in steel structures, roofing systems, machinery assembly, ventilation equipment, electrical cabinets, and construction industries. Stable quality, competitive pricing, and flexible customization make it an ideal solution for global B2B buyers.
The integrated flange under the hex head increases the bearing surface area and helps distribute tightening pressure evenly.
The Hex Flange Bolt design eliminates the need for separate washers in many applications, improving installation efficiency and reducing assembly costs.
The special thread design allows the bolt to create its own mating thread during installation, providing strong fastening performance without requiring pre-threaded holes.
The Flange Head Self Tapping Screw structure is widely used for sheet metal, steel plates, and lightweight industrial assemblies.
The integrated flange head increases the bearing surface area and helps distribute fastening pressure evenly.
The Flange Head Bolt reduces the need for additional washers and provides improved installation stability.
Hex Flange Head Self Tapping Bolts are produced through advanced cold heading, precision thread rolling, and heat treatment processes to achieve consistent mechanical properties and dimensional accuracy. The self tapping thread is designed to cut and form mating threads during installation, reducing assembly time while ensuring a secure connection.
The hex flange head provides a larger bearing surface than standard hex head bolts, helping distribute clamping force evenly and improving fastening stability. Surface finishes such as zinc plating, hot dip galvanizing, and Dacromet coating enhance resistance to corrosion and wear, making the bolts suitable for humid, outdoor, and industrial environments.
Each production batch undergoes comprehensive inspections, including dimensional measurement, thread gauge verification, torque testing, tensile strength testing, hardness testing, and coating thickness inspection. Strict quality control ensures every shipment meets export standards and customer specifications.
Available in a wide range of diameters, lengths, and coating options, these bolts can also be customized for specific applications, packaging requirements, and private label programs to support large-scale procurement and OEM projects.
The Zinc Plated Hex Flange Self Tapping Construction Bolt is widely used in:
