Flanged Metric Bolts: Secure Fastening with Built-In Washer Support
Flanged metric bolts are specialized fasteners designed to provide strong, secure, and evenly distributed clamping force. These bolts feature an integrated flange under the hex head, which acts like a built-in washer to spread the load and reduce the risk of damage to the bolted material. Whether used in automotive, construction, machinery, or industrial applications, flanged metric bolts ensure enhanced grip, ease of installation, and reliable performance.
Made according to international metric standards, flanged metric bolts are widely used across global industries where precision, strength, and consistency matter.
What Are Flanged Metric Bolts?
Flanged metric bolts are hex head bolts with a wide, flat flange that extends beneath the head. This flange helps to distribute the clamping force over a larger surface area, minimizing stress concentrations and improving the stability of the fastening. Unlike standard bolts, flanged metric bolts eliminate the need for a separate washer, simplifying assembly while maintaining high mechanical strength.
Key features of flanged metric bolts include:
Integrated Flange Head: Acts as a washer to reduce pressure and enhance load distribution.
Hex Drive: Allows easy installation with standard tools.
Metric Threading: Designed to fit metric nuts and components.
Various Grades and Finishes: Available in zinc-plated, black oxide, stainless steel, and more.
Benefits of Flanged Metric Bolts
Improved Load Distribution
The built-in flange of flanged metric bolts reduces surface stress, preventing the bolt from pulling through soft materials and enhancing overall joint integrity.Simplified Installation
Because the flange replaces the need for a separate washer, flanged metric bolts reduce part count and streamline the assembly process.High Vibration Resistance
The flange provides additional surface contact and resistance to loosening in high-vibration environments, making flanged metric bolts ideal for engines and heavy equipment.Corrosion Protection
Many flanged metric bolts are available with corrosion-resistant finishes such as zinc or stainless steel, making them suitable for indoor and outdoor use.Consistent Clamping Force
With standardized thread pitch and dimensions, flanged metric bolts deliver uniform tension and load-bearing capabilities across multiple applications.
Applications of Flanged Metric Bolts
Flanged metric bolts are widely used in:
Automotive Assemblies: Engine mounts, chassis, and suspension systems.
Heavy Machinery: Gearboxes, pumps, and hydraulic systems.
Construction and Infrastructure: Steel framework, bridges, and scaffolding.
Metal Fabrication: Equipment enclosures, control panels, and bracket mounting.
Electrical Installations: Panels, conduit supports, and grounding systems.
Their versatility, strength, and reliability make flanged metric bolts essential components in high-stress and precision-demanding environments.
Types of Flanged Metric Bolts
Serrated Flanged Metric Bolts
These feature radial serrations under the flange to bite into the material, offering greater resistance to loosening under vibration.Non-Serrated Flanged Metric Bolts
Smooth under the flange, ideal for applications where surface protection is critical.Fully Threaded vs. Partially Threaded
Choose fully threaded flanged metric bolts for thin materials and maximum engagement, or partially threaded types for higher shear strength.Different Grades
Available in property classes such as 8.8, 10.9, and 12.9 depending on the required strength.
Choosing the Right Flanged Metric Bolts
When selecting flanged metric bolts, consider the following:
Bolt Length and Diameter: Based on the thickness and type of materials.
Thread Pitch: Ensure compatibility with corresponding nuts or threaded holes.
Material and Finish: Select corrosion-resistant options for outdoor or marine use.
Serration Requirement: Serrated for high vibration; non-serrated for smoother finishes.
Always refer to relevant ISO or DIN standards for dimensional and strength specifications of flanged metric bolts.
Conclusion
Flanged metric bolts are a superior fastening solution where strength, stability, and efficient load distribution are essential. Their built-in flange offers numerous advantages—from improved vibration resistance to simplified installation—making them ideal across automotive, industrial, and construction sectors. With reliable performance and consistent quality, flanged metric bolts are the go-to choice for high-performance fastening systems.
