These serrated flange nuts are carbon steel with yellow zinc plating. The integrated flange with serrated teeth increases friction against the contact surface to prevent loosening under vibration. The flange spreads clamping pressure evenly without extra washers. They are commonly used for vehicle chassis, suspension, trailer frames and agricultural machinery. Multiple metric thread sizes are available.

FAQ
Q: What is yellow zinc plated serrated hex flange nut for truck chassis assembly used for?
A: This serrated flange nut is a self-anti-loosening fastener. The serrated teeth bite into the surface to increase friction, preventing nut loosening caused by vibration on chassis and trailer parts.
Q: Do I need to add an extra washer when using this nut?
A: Normally no, the built-in flange works as a washer to distribute pressure.
Q: What is the difference between yellow zinc and white zinc plating?
A: Yellow zinc plating provides better anti-corrosion performance than ordinary white zinc.
Q: Can these nuts be used on wheel hubs?
A: They are mostly for chassis and frame fastening. Wheel lug nuts use dedicated heavy-duty designs.
Q: Can you supply matching bolts?
A: Yes, we can provide matched hex bolts, carriage bolts and lock nuts as a set.
