Value Collection 011373PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 011373PR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Featuring a 1/2-13 UNC thread size and a 3/8-inch hex drive, this fastener is partially threaded with a 3.25-inch length under the head. Constructed from alloy steel with a black oxide coating, it delivers corrosion resistance and a clean finish suited for demanding service environments. Installation requires a 3/8-inch hex key or Allen driver. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for maintenance, repair, and OEM assembly work.

This cap screw is used across a wide range of commercial and industrial settings, including HVAC equipment frames, mechanical panel enclosures, pump and compressor assemblies, and general structural fabrication. It is suited for applications where a recessed drive head and high clamping force are required. The partial threading allows for proper load distribution in bolted joints where full thread engagement is not necessary or desirable. Machinists, millwrights, pipefitters, and maintenance technicians commonly install this fastener type.

Key Features

• 1/2-13 UNC thread form for broad compatibility with standard UNC tapped holes
• 3.25-inch length under head accommodates moderate-depth fastening applications
• 3/8-inch hex socket drive for secure torque transfer with standard hex keys or Allen drivers
• Partially threaded shank for proper load distribution in bolted assemblies
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection

Compatibility

Designed as a standard UNC hex socket cap screw for use in any application requiring a 1/2-13 internally threaded hole and a 3/8-inch hex drive fastener conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Install using a 3/8-inch hex key or Allen-drive tool; confirm the mating tapped hole meets 1/2-13 UNC thread specifications before installation. De-energize and lock out any equipment before performing fastener service on powered assemblies. Do not exceed the torque capacity of the hex drive socket or the rated shear strength of the fastener. Follow applicable facility maintenance procedures and any relevant ASME or OSHA guidelines for bolted joint assembly.
