Bolts: What You Need to Know

Bolts: What You Need to Know

Bolts, also known as threaded fasteners or mechanical connectors, are designed for securing metal, wood, and composite materials. They are available in various lengths (1-½ inches to 10 inches) and diameters (5/16 inch to 1-⅝ inches) to suit different load requirements and structural needs. With a range of head styles and materials, bolts provide high-strength fastening for construction, automotive, and industrial projects.

Types:

  • Carriage Bolts: Have a round head and a square neck that prevents rotation. Used in wood-to-metal connections for a smooth, secure finish.
  • Connecting Bolts: Designed for structural joints with high shear strength and precise threading for heavy-duty applications.
  • Eye Bolts: Feature a looped head for securing ropes, cables, and chains. Provide strong load-bearing capacity for lifting and anchoring.
  • Flange Bolts: Include a built-in washer-like flange under the head for increased load distribution and reduced surface damage.
  • Hex Bolts: Feature a six-sided head for high-torque tightening. Commonly used in construction and machinery.
  • U-Bolts: Shaped like the letter "U" and used to secure pipes, tubes, and round surfaces. Their threaded ends allow for strong clamping pressure.

Material:

  • Black: Provide enhanced corrosion resistance and a sleek finish for aesthetic and structural applications.
  • Galvanized: Coated with zinc to resist rust and corrosion. Ideal for outdoor and high-moisture environments.
  • Stainless Steel: Offer excellent corrosion resistance and strength. Suitable for marine and outdoor applications.
  • Zinc: Provide a protective barrier against corrosion while maintaining a clean finish.

Sizing:

  • #1 to #10: Ideal for small assemblies, machine parts, and lightweight construction.
  • #13 to #20: Used in general construction for framing, decking, and metal-to-metal fastening.
  • #23 to #50: Suitable for heavy-duty structural applications, including roofing, industrial setups, and load-bearing frames.
  • #60 to #120: Best for high-stress applications in industrial, automotive, and large-scale infrastructure projects.
