Value Collection 50120CH2 Hex Head Cap Screw 1/2-13

Product Description

The VALUE COLLECTION 50120CH2 is a partially threaded hex head cap screw sized at 1/2-13 x 7-1/2 inches, manufactured from Grade 2 steel with a zinc-plated finish. The 1/2-13 designation indicates a 1/2-inch nominal diameter with 13 threads per inch on a Unified National Coarse (UNC) thread form. The zinc plating provides basic corrosion resistance for general fastening applications in maintenance, mechanical assembly, and structural connections. This fastener meets ASME B18.2.1 and SAE J429 standards, confirming dimensional and mechanical-grade compliance. It is installed by maintenance technicians, millwrights, plumbers, pipefitters, and general tradespeople using standard hex tooling.

This cap screw is suited for general-purpose bolted connections in residential and commercial construction, HVAC equipment mounting, mechanical equipment assembly, and trade-service applications where a partially threaded grip is needed. The partial threading allows the unthreaded shank to pass through clearance holes and provide a clean bearing surface in the joint, which is standard practice for bolted structural and mechanical connections. Sold individually with a minimum order quantity of 25 pieces.

Key Features

• 1/2-13 UNC thread form for broad hardware compatibility
• 7-1/2 inch length under head suits deep-reach or through-bolt applications
• Partially threaded shank provides a clean bearing surface in bolted joints
• Grade 2 steel construction meets SAE J429 mechanical requirements
• Zinc-plated finish offers basic corrosion resistance in dry or mildly humid environments
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment

Compatibility

Designed as a general-purpose inch-series hex head cap screw compatible with any standard 1/2-13 UNC tapped hole or hex nut in mechanical, structural, and equipment-mounting applications.

Installation Notes

Install using a standard hex wrench, socket, or open-end wrench sized for a 1/2-inch hex head cap screw. De-energize and lockout any equipment before fastening components on live systems. Follow applicable torque guidelines from the equipment manufacturer or relevant codes such as AISC or ASME standards for the joint class. Do not substitute Grade 2 fasteners in applications that specify higher-grade hardware without verifying load requirements.
