Value Collection R52001347 Hex Cap Screw 1/2-13 X 10 in Grade 2

Product Description

The VALUE COLLECTION R52001347 is a partially threaded hex head cap screw designed for general fastening applications in mechanical, structural, and industrial assembly work. Sized at 1/2-13 (half-inch diameter, 13 threads per inch) with a 10-inch length under head, it conforms to UNC thread standards and meets ASME B18.2.1 and SAE J429 specifications. Constructed from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this fastener is suited for use in low-to-medium strength clamping and bolted joint applications. Machinists, millwrights, pipefitters, and general maintenance tradespeople commonly install this type of fastener.

This screw is appropriate for residential and light commercial construction, equipment mounting, and general mechanical assembly where Grade 2 steel strength is sufficient. The partial threading provides a smooth shank section near the head, which is useful in applications requiring a clamp length without thread engagement along the full grip. At 10 inches under head, it accommodates stacked material assemblies or through-bolt configurations in thicker workpieces or structural members.

Key Features

• Thread size 1/2-13 UNC, partially threaded with smooth shank under head
• 10-inch length under head for deep through-bolt and stacked-material applications
• Grade 2 steel construction per SAE J429 for general-purpose strength
• Zinc-plated finish provides basic corrosion protection in dry or mildly humid environments
• Conforms to ASME B18.2.1 dimensional standards for consistent hex head geometry

Compatibility

Designed as a general-purpose UNC hex head cap screw for use with standard 1/2-13 threaded holes, nuts, and inserts in steel, wood, and similar substrates where Grade 2 fastener strength is specified.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a standard hex socket or open-end wrench sized for a 1/2-inch bolt head. Ensure mating threads are clean and free of debris before engagement. Do not exceed torque values specified by the joint design engineer for Grade 2 fasteners, as this grade has lower proof load than Grade 5 or Grade 8. Thread lubricant or anti-seize may be applied per the application requirement.
