For machinery manufacturers, maintenance companies and industrial distributors, Heavy Duty Industrial Flange Bolts need to provide consistent dimensions, dependable fastening and suitable material performance. At Hanyang Machinery, I supply flange bolt solutions for machinery, equipment, structural and industrial applications, with support for wholesale, bulk and OEM purchasing.
As Alisa, Export Director at Hanyang Machinery with 10 years of industrial equipment export experience, I understand that international buyers need more than competitive pricing. Bolt diameter, length, thread, material, surface treatment and application requirements all need to be confirmed before production.

Technical note: Exact dimensions, thread pitch, material grade, mechanical class and surface treatment must be confirmed according to the selected SKU or technical drawing.
The flange head provides a wider bearing surface than a conventional hex-head bolt, making it suitable for applications where load distribution around the fastening point is important.
The appropriate bolt size and grade should always be selected according to the joint design and engineering requirements.
The product can be considered for machinery and equipment assemblies where reliable bolted connections are required.
Typical applications include:
Industrial machinery
Equipment frames
Mechanical assemblies
Steel structures
Maintenance and repair
Production equipment
We support:
Wholesale orders
Bulk purchasing
OEM production
Custom specifications
Export packaging
Repeat orders
Machinery OEMs can use Industrial Flange Bolts Wholesale for equipment assembly and replacement-part programs.
Buyers can specify bolt diameter, length, thread, material grade and surface treatment according to the machine design.
Maintenance teams need replacement fasteners that match existing equipment specifications.
Heavy Duty Flange Bolts Bulk purchasing can help MRO distributors and maintenance companies maintain commonly required bolt sizes in inventory.
Flange bolts can be considered for suitable metal and structural assemblies where the bolt specification meets the joint requirements.
Material grade, tightening torque and connection design should be confirmed by the project engineer.
For mechanical assemblies requiring a flanged fastening head, the product can be evaluated according to component dimensions, vibration conditions and required mechanical properties.
For Industrial Flange Bolts Custom projects, we can review drawings or samples for:
Diameter
Length
Thread
Material
Strength grade
Surface treatment
Packaging
Product labeling
Before purchasing, confirm:
Bolt diameter
Bolt length
Thread pitch
Material
Strength grade
Surface treatment
Joint thickness
Operating environment
Required tightening torque
For critical machinery or structural applications, bolt selection should follow the relevant engineering specification and applicable standard.
For a quotation, please provide:
Diameter + Length + Thread + Material + Grade + Quantity + Application + Finish
For OEM projects, technical drawings or samples allow our team to review the required dimensions before production.
We can also discuss customized packaging and labeling for distributors and private-label brands.
