Bolts

At South Coast Fasteners, Inc., we offer a broad range of bolts designed to fit the exact needs of professionals across industries. Whether you’re working on construction, manufacturing, automotive, or DIY projects, our bolts deliver the strength and reliability your work demands. From common hex bolts to specialized structural and anchor bolts, we provide solutions built to last.

• Hex Bolts
  The workhorses of fastening, with hexagonal heads for easy wrench grip. Made from steel or stainless steel in various sizes and grades, they fit countless applications from construction to machinery.

• Carriage Bolts
  Recognizable by their smooth rounded heads and square necks, carriage bolts are perfect for wood-to-metal or metal-to-metal connections. The square neck keeps the bolt from turning while tightening.

• Structural Bolts
  Heavy-duty bolts with large hex heads designed for strength and reliability in construction and engineering. Used with nuts and washers to secure steel frameworks, bridges, and other critical infrastructure.

• Tap Bolts
  Fully threaded bolts that screw directly into a pre-threaded hole or nut. They offer flexibility and are common in machinery, automotive, and furniture industries.

• Lag Screws
  Also called lag bolts, these are large wood screws with coarse threads and pointed tips, ideal for wood-to-wood or wood-to-metal fastening in decking, construction, and furniture.

• Flange Screws
  Screws with an integrated flange beneath the head that distributes load over a larger area, reducing damage and offering stable connections often used in automotive and machinery assembly.

• Plow Bolts
  Designed for heavy-duty applications like plow blades and agricultural equipment. They have flat, countersunk heads and square necks to resist rotation under stress.

• Step Bolts
  Featuring large flat heads and cylindrical shanks, step bolts are used in structural steel applications to provide secure footing on stairs and walkways.

• Elevator Bolts
  Used in conveyor systems and elevators, these bolts have large flat heads and are designed to evenly distribute load without damaging material.

• Timber Bolts
  Heavy-duty bolts with domed heads and square necks designed for timber construction and landscaping projects, providing strong wood connections.

• Square Head Bolts
  Bolts with square-shaped heads offering more grip in tight spaces, common in woodworking and machinery.

• Anchor Bolts
  Used to secure structural elements to concrete foundations, available in L and J shapes to fit different installation needs.

• Eye Bolts
  Bolts with looped heads for attaching cables or ropes, common in lifting, rigging, and marine applications.

• Toggle Bolts
  Designed for hollow materials like drywall, featuring spring-loaded wings that open to provide secure anchors for light to medium loads.

• Hanger Bolts
  Dual-threaded bolts with wood screw threads on one end and machine threads on the other, perfect for attaching hardware to wood.

Material and Grades

• Grade 2
  Basic bolts made from low or medium carbon steel, not heat-treated. Suitable for general low-strength applications.

• Grade 5
  Made from medium carbon steel, quenched and tempered for higher strength. Common in automotive and machinery uses.

• Grade 8
  High-strength bolts made from medium carbon alloy steel, heat-treated for maximum durability. Used in heavy machinery and structural projects.

• Stainless Steel
  Corrosion-resistant bolts, ideal for wet or chemical environments. Common grades include 18-8 (Type 304) and 316 stainless steel.

• Alloy Steel
  Heat-treated bolts designed for increased strength and durability, used in high-stress applications.

Plating Options

• Zinc Plating
  Offers corrosion resistance and a decorative finish, suitable for general outdoor use.

• Hot-Dip Galvanizing
  Thick, durable zinc coating applied by dipping, excellent for harsh outdoor environments.

• Cadmium Plating
  Provides corrosion resistance and lubricity for aerospace and military, though restricted due to environmental concerns.

• Nickel Plating
  Corrosion-resistant with a bright finish, popular for decorative and high-performance applications.

• Chrome Plating
  Shiny, corrosion-resistant coating often used in automotive and motorcycle hardware.

• Black Oxide Coating
  Dark finish that improves corrosion resistance and offers a sleek look, common in machinery and firearms.
