Hex Head Flanged Screw Selection — Quick Reference
Hex head flange screws = SECURE + VIBRATION-RESISTANT fastening for metalwork + machinery + structural applications. Integrated flange = wider bearing surface + load distribution + visual stand-off — no washer required.
| Flanged Screw Type | Best For |
|---|---|
| Standard Hex Flange Screw | Workshop + general fastening |
| Serrated Flange Screw | Vibration resistance — teeth bite mating surface |
| Smooth Flange Screw | Won't mark finished surface |
| Class 8.8 / Class 10.9 / Class 12.9 | Tensile strength grades |
| Zinc-Plated Standard | Indoor + general — common workshop |
| 304 / 316 Stainless | Corrosion + chemical + marine |
| Hot-Dip Galvanised | Heavy outdoor + extended corrosion |
| Metric (M5-M16+) | AU + EU engineering |
| UNC / UNF (Imperial) | US-origin equipment |
Critical: Serrated flange = effectively LOCKING fastener — bite into mating surface prevents loosening. ONE-TIME use generally — serrations damage surface. Smooth flange = reusable but no inherent locking. Match grade to bolted joint torque + load. Companion: flanged nuts, hex bolts, all fasteners, torque chart.
Hex head flange screws provide a secure, vibration-resistant fastening solution for metalwork, machinery and structural applications. Available in metric and imperial sizes, stainless steel, zinc plated and high tensile grades, our selection suits automotive, fabrication and general engineering projects. The integrated flange spreads load and removes the need for a washer, simplifying assembly while improving clamp strength. Choose fine or coarse thread profiles and thread lengths matched to panel thickness for reliable joints.
Engineered for repeatable performance, each hex head flange screw is sourced from trusted brands and inspected for thread accuracy and material quality. Worldwide delivery is available, with free shipping on orders over $299 for major Australian cities. *Terms and conditions apply. Browse by size, grade and head style to find compatible hex head flange screws, nuts and washers for your project.

People Also Ask — Hex Head Flanged Screws
Q: What's the difference between a serrated and a smooth hex head flange screw?
A serrated flange has teeth that bite into the mating surface, acting as an effectively locking fastener that resists loosening, while a smooth flange is reusable but has no inherent locking action.
Q: Why can't a locking flange fastener reliably be reused after removal?
The serrations damage the mating surface as they bite in, so removing and re-fitting the same screw won't reproduce the same locking bite a second time.
Q: Why doesn't a hex head flange screw need a separate washer?
The integrated flange already gives a wider bearing surface that spreads the load, doing the same job a washer would without needing a separate component.
Q: When does a screw need to sit flush against a finished surface without leaving bite marks?
Where the screw needs to sit against a finished surface without marking it, since the serrations on a locking flange would leave bite marks.
Q: What thread standards does the hex head flange screw range cover?
Both metric and UNC/UNF imperial thread standards, matched to fine or coarse thread profiles and length to suit panel thickness.
