Technical Superiority: How Non-Serrated Flange Nuts Outperform
Traditional serrated flange nuts? They rely on teeth that wear down after 3-5 stress cycles. Our non-serrated 1/4-28 flange nuts use patented radial compression. Test data shows 40% higher torque retention at 90+ psi vibration environments.

FAQS on 1 4 28 flange nut non serrated
Q: What is the difference between a 1/4-28 flange nut non-serrated and a 1/4-20 serrated flange nut?
A: The 1/4-28 non-serrated flange nut has a smooth flange for even pressure distribution, while the 1/4-20 serrated version has teeth to prevent loosening under vibration. Thread sizes differ: 1/4-28 (UNF) vs. 1/4-20 (UNC).
Q: Where are non-serrated flange nuts typically used?
A: Non-serrated flange nuts are ideal for static applications requiring uniform clamping force, like machinery assemblies or plumbing fixtures. They avoid surface damage from serrations and suit softer materials.
Q: Can I replace a serrated flange nut with a non-serrated one?
A: Only in low-vibration environments. Non-serrated nuts lack locking teeth, making them unsuitable for dynamic loads. Always verify torque and application requirements first.
Q: What tools are needed to install a 1/4-28 non-serrated flange nut?
A: Use a standard wrench or socket matching the nut’s size (typically 7/16" hex). A torque wrench ensures proper tightening without over-compressing the flange.
Q: How do I choose between 1/4-28 and 1/4-20 flange nuts?
A: Match the nut’s thread to the bolt’s (1/4-28 UNF or 1/4-20 UNC). Use serrated for vibration resistance and non-serrated for smooth surfaces or delicate materials.
