Fastening hardware built to resist loosening and secure assemblies for workshop, automotive and construction tasks, RC Screws Serrated Flange Hex Nuts. That brings reassurance for mechanics, engineers and hobbyists who face vibration and regular use. Are these the reliable fasteners your projects need?
⚡ At a Glance
- • Holding Strength: Serrated flange surface provides superior grip and prevents loosening under vibration
- • Best for: General engineering, automotive, machinery and construction applications requiring secure fastening
- • Not ideal for: Situations that require smooth, non-serrated or purely decorative fasteners
Serrated flange hex nuts in bright zinc plated steel, supplied in packs of 20. Designed for demanding applications where vibration resistance and repeatable fastening matter.
Secure joints under vibration – with serrated flange
Serrations on the flange bite into the mating surface, increasing friction and creating a mechanical locking action that resists rotation. The flange spreads load across a wider area to reduce stress on the joint.
Keeps assemblies such as automotive and machinery components clamped reliably during movement and vibration. Reduces the need for secondary locking washers in many applications.
Reliable thread engagement – with precise threads
Cleanly formed threads ensure consistent pitch and engagement along the bolt, reducing the chance of cross-threading during installation. Even load distribution along the thread length improves torque repeatability.
Simplifies installation and gives predictable torque control for workshop and production work. Results in fewer damaged fasteners and more reliable assemblies.
Protective finish for extended use – with bright zinc plated steel
Bright zinc plating provides a protective metallic coating over the steel substrate, helping resist surface corrosion while retaining a neat finish. Steel core preserves the mechanical strength required for fastening.
Suitable where a plated protective finish is preferred alongside strength from a steel fastener. Maintains appearance and function in general engineering and maintenance settings.
