Fastener Bolts: Types, Uses & Best Manufacturers
What Are Fastener Bolts?
Fastener bolts are threaded fasteners used to join materials securely in construction, automotive, and industrial applications. They provide high tensile strength and reliability for various structural needs.
Types of Fastener Bolts
Type | Features | Common Applications |
---|---|---|
Hex Bolts | Six-sided head, strong grip | Machinery, construction |
Carriage Bolts | Round head, square neck | Wood and metal fastening |
Anchor Bolts | Embedded in concrete | Structural foundations |
Flange Bolts | Integrated washer | Automotive, heavy-duty machines |
Eye Bolts | Loop at one end | Lifting, rigging applications |
U-Bolts | U-shaped with threads | Pipe and tube fastening |
Choosing the Right Fastener Bolt
Consider These Factors:
✅ Material: Stainless steel, carbon steel, or titanium based on strength needs.
