Industrial Fasteners: A Comprehensive Guide to Bolts, Nuts, and Washers

Fasteners are the unsung heroes of industrial manufacturing, holding together everything from simple assemblies to complex machinery. At CDCOMPOSITE, we supply a comprehensive range of high-quality industrial fasteners to meet the most demanding applications.

Understanding Fastener Grades

Bolt Grades

The grade of a bolt indicates its mechanical properties, particularly tensile strength:

Stainless Steel Grades

For corrosion resistance, we offer various stainless steel options:

• A2 (304): General purpose, good corrosion resistance
• A4 (316): Marine grade, superior corrosion resistance
• Duplex: High strength with excellent corrosion resistance

Types of Fasteners

Bolts

Our bolt range includes:

• Hex bolts: Standard industrial fastening
• Carriage bolts: Smooth dome head for security
• Anchor bolts: Foundation and structural applications
• Eye bolts: Lifting and rigging applications
• U-bolts: Pipe and conduit clamping

Nuts

Complementary nut options:

• Hex nuts: Standard pairing with hex bolts
• Lock nuts: Vibration-resistant applications
• Flange nuts: Built-in washer for load distribution
• Coupling nuts: Rod extension and joining
• Wing nuts: Tool-free assembly/disassembly

Washers

Essential load distribution and protection:

• Flat washers: Load distribution
• Spring washers: Vibration resistance
• Lock washers: Anti-loosening
• Fender washers: Large bearing surface
• Belleville washers: High-load spring action

Material Selection Guide
