Engineering Superiority: Why Our Serrated Flange Hex Nuts Outperform

Our serrated flange hex nuts feature dual-security technology: 360° radial serrations (0.012" depth) + 12-point flange contact. Tested to withstand 45 ft-lbs torque – 22% higher than ISO 4161 standards. Choose from zinc-plated or stainless steel variants with temperature resistance from -65°F to +450°F.

Precision Match: How We Beat Generic 1/4-20 Serrated Flange Nuts

Why settle for undersized 1/4-20 serrated flange nuts when our 5/16-18 variants deliver 38% greater load distribution? Our flange diameter (0.875" vs 0.656") and serration count (72 vs 48) outperform competitors in stress tests.

FAQS on 5 16 18 serrated flange nut

Q: What is the purpose of a serrated flange hex nut?

A: A serrated flange hex nut combines a hexagonal nut with an integrated flange featuring serrations. The serrations grip surfaces to resist loosening from vibration, while the flange distributes pressure evenly.

Q: What applications suit a 5/16-18 serrated flange nut?

A: The 5/16-18 serrated flange nut is ideal for automotive, machinery, and structural applications requiring vibration resistance. Its 5/16" diameter and 18 threads-per-inch ensure secure fastening in high-stress environments.

Q: How does a serrated flange hex nut differ from standard nuts?

A: Unlike standard nuts, serrated flange hex nuts have a built-in washer-like flange with teeth. This design eliminates the need for separate washers and provides anti-vibration locking without adhesives.

Q: Can a 1/4-20 serrated flange nut be used in outdoor environments?

A: Yes, if made from stainless steel or coated materials. The 1/4-20 serrated flange nut resists corrosion and maintains grip in outdoor or humid conditions when paired with compatible hardware.

Q: What tools are required to install a 5/16-18 serrated flange nut?

A: Use a standard 1/2" wrench or socket. The serrated flange nut installs like a regular hex nut but requires sufficient torque to engage the serrations with the mating surface for vibration resistance.
