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.

Bolts FAQ

Which bolts are best for outdoor construction in Los Angeles?

 For outdoor construction in Los Angeles, galvanized and stainless steel bolts are the best choice. These materials resist corrosion caused by coastal air, sun exposure, and seasonal weather. Common uses include decks, fencing, and structural framing where durability is critical. Supply Ontime carries a wide range of corrosion-resistant bolts, ensuring contractors and homeowners get the fasteners needed for long-lasting outdoor builds.

What is the advantage of using U-bolts in construction projects?

The advantage of using U-bolts is their ability to secure pipes, conduit, or round objects to flat surfaces. They’re commonly used in plumbing, electrical, and mechanical applications across Los Angeles construction sites. With included nuts and straps, U-bolts provide strong, stable fastening that standard bolts can’t achieve. Supply Ontime keeps U-bolts in multiple sizes and finishes, available for quick delivery to job sites citywide.
