Holo-krome 720002510 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The HOLO-KROME 720002510 is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural components. It carries a 1/2-13 UNC thread size and measures 4-3/4 inches under the head. The drive is a 3/8-inch internal hex socket, requiring a standard Allen or hex key for installation and removal. The fastener is manufactured from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection. This screw is typically installed by millwrights, maintenance mechanics, and industrial technicians working on machinery, equipment frames, and fixture assemblies.

This hex socket cap screw is suited for applications requiring a low-profile head, flush clearance, or recessed fastening in tight spaces where a standard hex bolt head would interfere. Its partial threading allows for precise clamping force in through-bolt configurations where a fully threaded fastener is not appropriate. It meets ASME B18.3 and ASTM A574 standards, making it appropriate for industrial and commercial mechanical applications where dimensional and strength compliance is specified.

Key Features

• 1/2-13 UNC thread size for compatibility with standard inch-series tapped holes and nuts
• 4-3/4 inch length under head accommodates thicker stackups and structural members
• 3/8-inch hex socket drive allows precise torque application with standard hex keys or socket drivers
• Partially threaded shank provides accurate clamping without thread engagement across the shear plane
• Alloy steel construction delivers high tensile and shear strength for demanding load conditions
• Black oxide finish reduces surface corrosion and minimizes galling during installation
• Meets ASME B18.3 and ASTM A574 standards for dimensional and mechanical property compliance

Compatibility

Designed as an OEM-style replacement or standard hex socket cap screw for industrial machinery, equipment assemblies, and structural fixtures requiring a 1/2-13 UNC partially threaded fastener with a 3/8-inch hex socket drive.

Installation Notes

Installation is typically performed by millwrights or maintenance mechanics using a calibrated torque wrench with a 3/8-inch hex bit or Allen key. De-energize and lock out all equipment before fastener service per applicable OSHA lockout/tagout procedures. Inspect the tapped hole for thread condition and debris before installation. Do not exceed the torque specifications listed in the applicable equipment service manual or ASME fastener guidelines for this size and grade.
