Tap Bolts - Material Options

South Coast Fasteners stocks tap bolts in materials selected for durability, corrosion resistance, and reliable performance in everyday and specialized applications.

A307 Grade A

A solid choice for general-purpose fastening. These low carbon steel bolts are used in non-critical assemblies where heavy load or high temperature is not a concern. A307 Grade A tap bolts are often found in light construction, HVAC systems, and fixture mounting where strength and simplicity are both required.

Brass

Known for its natural resistance to corrosion, brass is ideal when aesthetics, conductivity, or moisture exposure are a factor. These tap bolts are common in plumbing systems, marine hardware, and decorative installations where a clean finish matters as much as performance.

Grade 5

Made from medium carbon steel and heat-treated for added strength, Grade 5 tap bolts are a dependable option for automotive repairs, agricultural equipment, and machinery. They offer increased tensile strength over standard grades and can handle moderate stress without deformation or premature wear.

Grade 8

Grade 8 hex tap bolts are made from medium carbon alloy steel, heat-treated for maximum strength and durability. They’re ideal for high-stress applications such as heavy machinery, construction equipment, and automotive assemblies. Known for their superior tensile strength and reliability under load.

Tap Bolts - Available Finishes

South Coast Fasteners offers tap bolts in finishes selected to provide corrosion resistance, wear protection, and visual clarity across multiple industries.

Hot Dip Galvanized

This heavy-duty zinc coating protects steel tap bolts from rust and surface wear in outdoor, coastal, or wet environments. The finish is commonly used in structural framing, fencing systems, and infrastructure installations where weather resistance is a top concern.

Plain

Raw, uncoated steel for indoor applications or projects where the bolts will be painted or treated after installation. This finish is simple, cost-effective, and perfect for custom fabrication or controlled environments.

Yellow Zinc Cr+6

This bright, chromate-rich finish offers improved corrosion resistance with a gold appearance that makes inspection and part ID easier. Yellow zinc is widely used in automotive, electrical, and industrial assemblies where performance and visibility go hand in hand.
