Hex Tap Bolts

Hex Tap Bolts for Secure and Versatile Threaded Fastening

Hex tap bolts are fully threaded hex head fasteners designed for strong, reliable performance in construction, machinery, and industrial assemblies. Often confused with hex cap screws, hex tap bolts feature a fully threaded body and are commonly used in tapped holes rather than with a nut. Their uniform threading and hex head design provide excellent clamping force and easy installation with standard wrenches or sockets.

What Are Hex Tap Bolts?

Hex tap bolts are externally threaded fasteners with a six-sided head and continuous threading from under the head to the tip. Because they are fully threaded, they provide maximum thread engagement in pre-tapped holes, making them ideal for precision mechanical applications.

Common characteristics include:

• Fully threaded shank

• Standard hex head design

• Available in coarse (UNC) and fine (UNF) thread pitches

• Manufactured to industry standards such as ASME dimensional specifications

Materials and Finishes

Carbon Steel Hex Tap Bolts

Carbon steel hex tap bolts are widely used for general-purpose fastening. They offer excellent tensile strength and cost-effective performance for structural and mechanical applications.

Available finishes include:

• Plain (oil finish)

• Clear zinc plating (Cr3)

• Yellow zinc plating

• Hot-dip galvanized for corrosion resistance

Stainless Steel Options

Stainless steel hex tap bolts, such as 18-8 or 316 stainless, provide enhanced corrosion resistance for marine, food processing, and outdoor environments.

Industrial Applications

Hex tap bolts are commonly used in:

• Equipment assembly

• Steel fabrication

• HVAC systems

• Automotive repair

• Maintenance and repair operations (MRO)

Because they are fully threaded, hex tap bolts are especially effective where full-length thread engagement is required for maximum holding power.

Key Benefits

• Strong, uniform thread engagement

• Easy installation with standard tools

• Wide range of sizes and finishes

• Suitable for tapped holes or nut applications

For dependable fastening in industrial and commercial settings, hex tap bolts deliver strength, versatility, and long-lasting performance.
