Precision Fastening for High-Performance Applications
When it comes to industrial fastening solutions, reliability, strength, and precision are non-negotiable. That’s exactly what the ISO 15071 Hex Head Flange Bolts – Small Series deliver. These high-performance fasteners are engineered to meet the exacting ISO 15071 standard, combining a compact flange head with exceptional load distribution, making them ideal for a wide range of mechanical and structural applications.
? What Are ISO 15071 Hex Head Flange Bolts – Small Series?
The ISO 15071 Hex Head Flange Bolts – Small Series are a specific category of metric flange bolts that feature a smaller head diameter and narrower flange, designed for applications where space is limited, but performance is crucial. Unlike standard hex bolts, these fasteners include an integrated flange that acts as a washer to distribute pressure evenly over the material being fastened.
Key features include:
Hexagonal head for easy torque application
Smaller flange diameter (Small Series) to fit tight spaces
Designed per ISO 15071 standards
Available in a wide range of metric sizes (M5 – M16)
High-grade materials: carbon steel, stainless steel, and zinc-plated finishes
? “We’ve used ISO 15071 Hex Head Flange Bolts in all our compact assemblies where space was tight and clamping force was critical. Flawless every time.”
— Jason K., Mechanical Engineer
?️ Key Applications for ISO 15071 Flange Bolts – Small Series
Thanks to their design and reliability, these bolts are widely used in industries such as:
Automotive & EV Assembly
Compact Gearboxes & Motors
Precision Machinery
Aerospace Components
Construction Equipment
The smaller flange reduces weight and footprint, which is critical in high-precision or mobile applications.
✅ Why Choose ISO 15071 Bolts Over Standard Flange Bolts?
Feature | ISO 15071 Small Series | Standard Flange Bolt |
---|---|---|
Flange Size | Smaller & space-saving | Larger footprint |
Applications | Compact & weight-sensitive | General purpose |
Standards Compliance | ISO 15071 | Varies |
Torque Efficiency | High | High |
Integrated Washer | Yes | Yes |
⭐ “The reduced flange size helped us streamline our electric motor casing without sacrificing bolt strength.”
— Liam D., Product Designer

? Choosing the Right ISO 15071 Bolt
When selecting ISO 15071 Hex Head Flange Bolts – Small Series, consider:
Space constraints in your design
Load-bearing requirements
Environmental exposure (stainless steel for high corrosion areas)
Torque specifications per your equipment’s requirement
Need help selecting the right size or material? Our engineering team is ready to help you spec the perfect fastener.
? Installation Tips
Always use a calibrated torque wrench to avoid over-tightening.
Pair with matching ISO nuts and washers for maximum performance.
Consider anti-seize compound for stainless steel bolts in high-temperature applications.
⚠️ Pro Tip: Do not substitute Small Series bolts with regular flange bolts — the flange dimensions and thread engagements are different and can affect performance.
