Flange Bolts in China
Flange bolts need the flange treated as part of the function, so supplier comparison should cover flange diameter, serration, head style, grade, coating, thread rolling, and inspection. Haizol helps you review Chinese fastener factories before production.
The RFQ should define thread size, length, flange diameter, serration requirement, head height, grade, material, coating, quantity, and certificate needs. Those details affect load distribution and the manufacturing route.
A clear RFQ should include thread size, length, flange diameter, serration requirement, head style, grade, material, coating, quantity, and certificate needs. Haizol profiles help you review heading and flange-forming equipment, gauges, QC machines, claimed certifications, factory photos, and similar flange bolt work.
If the project needs a standard hex head, compare hex bolts. If the assembly also uses flanged mating hardware, review flange nuts before sending the RFQ.
Haizol helps you compare flange bolt suppliers using profile evidence: heading and flange-forming equipment, gauges, QC machines, claimed certifications, factory photos, and similar flange bolt work.

Frequently Asked Questions
What Types of Flange Bolts Can Factories Make?
Flange bolt types vary by flange diameter, serration, head height, grade, thread length, material, and coating. Those details affect load distribution and assembly behavior, so they should be fixed before factories compare tooling, heading, thread rolling, and inspection.
What Specifications Matter When Sourcing Flange Bolts by Size?
For flange bolts by size, include thread size, length, flange diameter, serration requirement, grade, material, coating, and quantity. The flange dimensions matter because they change the bearing surface and the manufacturing route.
What Should I Check Before Sourcing Flange Bolts?
Before sourcing flange bolts, check flange diameter, serration, head geometry, thread rolling, grade control, coating, and gauge inspection. Haizol profiles help confirm whether a Chinese fastener factory can control the flange feature as part of the bolt, not as a generic head style.
What Is the Flange Bolt?
Flange bolts have an integrated flange under the head to spread load over a wider bearing surface. Serration, flange diameter, head style, grade, coating, and thread standard affect both performance and quote comparison. On Haizol, you can compare Chinese factories by heading and flange forming capability, thread rolling, heat treatment, coating, dimensional gauges, and product examples before sending the RFQ.
What Is the Difference Between a Hex Bolt and a Flange Bolt?
A hex bolt has a standard hex head, while a flange bolt adds an integrated flange under the head to spread load over a wider bearing surface. Serration, flange diameter, grade, coating, and mating surface condition should be defined before comparing factories. On Haizol, the directory step is to compare Chinese factories by heading and flange forming capability, thread rolling, heat treatment, coating, dimensional gauges, and product examples before sending the drawing package.
