Flange Screws

South Coast Fasteners, Inc. supplies flange screws, also known as flange bolts, are designed for secure fastening with built-in load distribution. Featuring an integrated washer-like flange under the hex head, these screws spread the clamping force over a larger area reducing the need for separate washers and providing a cleaner, more efficient install. Flange screws are commonly used in automotive assembly, manufacturing, and heavy equipment applications where vibration resistance and surface load control matter.

Flange Screws - Material Options

South Coast Fasteners stocks flange screws in material grades selected for strength, corrosion resistance, and application-specific reliability.

Grade 10.9

This high-strength metric option is engineered for structural assemblies, automotive frames, and heavy-duty equipment where tensile strength and resistance to vibration matter. Grade 10.9 flange screws are frequently found in suspension systems, critical torque joints, and machine assembly work that demands consistent performance under load.

Grade 5

These medium carbon steel screws are heat-treated to provide solid strength and reliability in general manufacturing, machinery assembly, and automotive work. Grade 5 is a dependable, everyday solution when you need a screw that can handle torque, shock, and long-term use.

Grade 8

With greater tensile and yield strength than Grade 5, Grade 8 flange screws are built for high-stress fastening in demanding environments. They are widely used in engine components, structural brackets, and load-bearing connections where failure is not an option.

Grade 8.8

The metric counterpart to Grade 5, Grade 8.8 provides strong and steady performance in a wide range of industrial and commercial settings. It is ideal for manufacturers working with metric components who need strength and compatibility without over-engineering.

Stainless Steel

This versatile option offers excellent durability and corrosion resistance. Stainless flange screws are used across food processing, medical equipment, outdoor installations, and chemical environments where a clean finish and dependable longevity are both required.

Stainless Steel 18-8

A premium stainless alloy known for its superior corrosion resistance, 18-8 stainless is a great choice for flange screws used in marine, coastal, and wet environments. These screws maintain their appearance and function over time, making them a top pick for visible or outdoor applications.

Flange Screws - Available Finishes

South Coast Fasteners offers flange screws in finishes that extend the life of the fastener, protect against corrosion, and support industry-specific requirements.

Black Phosphate and Oil

A dark, matte finish that provides light corrosion resistance while reducing glare and improving lubricity during installation. This finish is often used in automotive assemblies, engine compartments, and industrial machinery where a clean, low-profile look is preferred.

Zinc Bake Cr+6

This plated finish offers improved corrosion resistance with a baked-on coating that enhances durability and helps minimize hydrogen embrittlement. Zinc Bake Cr+6 is ideal for high-strength flange screws used in structural joints, pressurized equipment, and vibration-heavy installations.

Zinc Cr+3

A bright silver finish that offers dependable rust resistance for general industrial use. Zinc Cr+3 flange screws are popular in equipment assembly, building maintenance, and metal fabrication where both aesthetics and protection matter.
