Holo-krome 720003365 Hex Socket Cap Screw 3/4-10 Unc

Product Description

The HOLO-KROME 720003365 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. It features a 3/4-10 UNC thread and measures 12 inches in length under the head with partial threading. The 5/8-inch hex drive socket accepts a standard hex key or Allen driver. Manufactured from alloy steel with a black oxide finish, it delivers corrosion resistance and maintains dimensional integrity under load. This fastener meets ASME B18.3 and ASTM A574 standards, making it appropriate for demanding mechanical and industrial environments where tensile strength and precision fit are required.

This cap screw is suited for heavy machinery assembly, structural steel fabrication, maintenance and repair operations, and industrial equipment manufacturing. The 3/4-10 UNC thread pitch is a coarse-thread designation commonly used where fast assembly is needed or where thread stripping in softer tapped materials is a concern. The partial threading and 12-inch length under head make it well suited for through-bolt and long-reach fastening applications. It is installed by maintenance technicians, millwrights, and mechanical contractors working on production equipment, frames, and structural components.

Key Features

• 3/4-10 UNC coarse thread for reliable engagement in standard tapped holes
• 12-inch length under head accommodates long-reach and through-bolt applications
• Partial threading provides unthreaded shank section for shear-load resistance
• 5/8-inch hex socket drive compatible with standard hex keys and Allen drivers
• Alloy steel construction meets ASTM A574 high-strength cap screw requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection

Compatibility

Designed as an OEM-style fastener replacement for industrial and mechanical applications requiring a 3/4-10 UNC hex socket cap screw conforming to ASME B18.3 and ASTM A574 standards.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or mechanical contractors using a calibrated torque wrench with the appropriate 5/8-inch hex bit. Always ensure the mating tapped hole is clean, properly formed, and free of debris before installation. De-energize and lock out all equipment before fastening work begins on any machinery or structural assembly. Refer to the equipment manufacturer specifications for required torque values, as these vary by application and joint design.
