Carbon Steel Hexagon Cap Nuts
Product Overview
Hexagon Cap Nuts, also known as acorn nuts, are a type of fastener designed with a domed top to protect screw threads and provide a finished appearance. Typically used in applications where exposed threads need protection from external elements or aesthetic integration is desired, these nuts serve both functional and decorative purposes. With their six-sided design, hex cap nuts offer excellent grip and can be easily installed using standard tools. The carbon steel construction ensures strength and durability, while optional coatings enhance corrosion resistance. Flybear Fastener offers a wide range of high-performance hexagon cap nuts tailored to industrial, automotive, and construction needs.

Material and Manufacturing Process
Hexagon Cap Nuts from Flybear Fastener are primarily made from high-quality carbon steel, selected for its excellent machinability and mechanical strength. The production process includes precision cold forging to achieve the desired dome shape and uniform thread formation. Threads are then rolled to enhance fatigue resistance. Depending on customer requirements, a range of coatings such as zinc plating or black oxide are applied for corrosion resistance. Each finish is carefully tested to ensure it meets industry performance standards. Advanced CNC equipment ensures minimal size deviations, offering end-users confidence in fit and functionality.
Common Applications and Industries
Hexagon Cap Nuts are widely used in various industries that prioritize both mechanical safety and cosmetic appearance. Applications include:
- Automotive: Securing wheel bolts and under-the-hood assemblies
- Construction: Architectural paneling and exposed fastener systems
- Electrical Equipment: Enclosures, switchboards
- Furniture: Assembly of wood or metal structures
- Machinery: Equipment housings and gear covers
- DIY and home projects
Their compatibility with a wide range of thread types and materials makes hexagon cap nuts a go-to solution for engineers and maintenance professionals.
