Value Collection R52001242 Hex Head Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R52001242 is a partially threaded hex head cap screw designed for general-purpose mechanical fastening applications. It features a 5/8-11 UNC thread and a 6.5-inch length under head, making it suitable for through-bolt and bolted-joint assemblies where full thread engagement is not required. Manufactured from Grade 2 steel with a zinc-plated finish, it offers basic corrosion resistance appropriate for indoor and sheltered environments. This fastener conforms to ASME B18.2.1 and SAE J429 standards and is installed by millwrights, pipefitters, plumbers, electricians, and general mechanical contractors working with structural and equipment connections.

This cap screw is commonly used in light to medium-duty bolted assemblies across residential and commercial construction, equipment mounting, and mechanical infrastructure. The partial threading allows the unthreaded shank to act as a bearing surface in clearance holes, providing shear resistance in appropriate joint designs. It is well suited for use with standard hex nuts and flat or lock washers in inch-series hardware installations.

Key Features

• 5/8-11 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes
• 6.5-inch length under head accommodates assemblies requiring a longer fastener with partial thread engagement
• Grade 2 steel construction meets SAE J429 and ASME B18.2.1 specifications
• Zinc-plated finish provides basic corrosion resistance in sheltered environments
• Partially threaded shank offers shear-bearing surface in clearance-hole joints

Compatibility

Designed for use with standard 5/8-11 UNC hex nuts, flat washers, and lock washers in inch-series bolted assemblies conforming to ASME and SAE fastener standards.

Installation Notes

Install using a standard 15/16-inch hex wrench or socket driver. Ensure mating threads and seating surfaces are clean and free of debris before assembly. Apply appropriate torque per the joint design requirements specified by the engineer of record or applicable mechanical code. Do not use in applications requiring Grade 5 or Grade 8 fastener ratings without confirming Grade 2 suitability for the load conditions involved.
