Ananka Group is a trusted hex flange bolt manufacturer. Hex flange bolts are robust fasteners with an integrated flange beneath the hexagonal head, designed to distribute load over a wider surface area. This built in washer effect eliminates the need for a separate washer and improves resistance to loosening caused by vibration or torque. These bolts are made out of stainless steel, carbon steel and alloy steel and have protective surface coatings like zinc plating, black oxide, or hot dip galvanizing for extra corrosion protection.
The design of the flange provides even load distribution, minimizes damage to the contact surfaces and strengthens resistance under dynamic loads. Available in fully and partially threaded versions, they adhere to international specifications such as DIN 6921, ISO 4162 and ASME B18.2.1 for universal application compatibility. Designed specifically for B2B environments that feature dimensional precision, long term joint integrity and conformity to international standards, the bolts are the choice for high strength bolting in various critical industries.
Corrosion resistant fastener ideal for automotive and structural use.
Designed for high load assemblies in heavy machinery and engine systems.
What is a hex flange bolt?
A hex flange bolt is a type of fastener that features a hexagonal head with an integrated flange or washer like base. The flange helps distribute the clamping load over a wider area, improving grip and reducing the risk of damage to the joint surface. The integrated flange removes the need for a separate washer, streamlining installation while improving grip and resistance against vibration or loosening forces. Hex flange bolts are commonly used in high load mechanical assemblies across industries such as automotive, structural steel and heavy equipment.
What are hex flange bolts used for?
Hex flange bolts are used to fasten components where strong, vibration resistant clamping is needed. They are widely applied in automotive frames, machinery enclosures, heavy equipment, metal fabrication and infrastructure joints. The flange base provides enhanced stability by spreading the load, making them ideal for securing components subject to constant movement or torque. These bolts are especially useful in high torque applications where maintaining long term joint integrity is critical, including powertrain assemblies and steel construction.
What is the difference between a standard bolt and a hex flange bolt?
The key difference between a standard bolt and a hex flange bolt lies in the head design. While standard bolts typically require a separate washer to distribute pressure, hex flange bolts feature an integrated flange beneath the head that performs this function. This built in flange offers better load distribution, reduces loosening under vibration and improves installation efficiency. Hex flange bolts are preferred for dynamic environments or where simplified assembly and stronger fastening are required without the need for additional components.
