Value Collection R52000927 Hex Head Cap Screw Grade 2

Product Description

The VALUE COLLECTION R52000927 is a partially threaded hex head cap screw designed for general-purpose fastening in structural and mechanical assemblies. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this fastener measures 1-8 thread size with a 3.5-inch length under head. The UNC (Unified National Coarse) thread form provides reliable engagement in standard tapped holes and nuts. It conforms to ASME B18.2.1 and SAE J429 standards, making it suitable for applications where dimensional and strength compliance is required. Installers across general construction, light fabrication, and mechanical maintenance will find this a practical stock fastener.

This cap screw is suited for residential and light commercial construction, equipment assembly, and general maintenance work where a Grade 2 steel fastener with coarse threading meets the load and torque requirements. The partial threading leaves a shank section that aids alignment and shear load distribution in through-bolt applications. It is appropriate for wood-to-metal connections, framing hardware, brackets, and similar structural fastening tasks where a standard hex head drive is specified.

Key Features

• Grade 2 steel construction meets SAE J429 minimum tensile strength requirements for general fastening
• Zinc-plated finish provides basic corrosion protection in dry and mildly humid environments
• Partially threaded shank aids alignment and handles shear loads in through-bolt applications
• UNC thread form for compatibility with standard coarse-thread nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standards for hex head cap screws
• Hex head drive accepts standard hex wrenches and sockets for installation and removal

Compatibility

Designed as a standard UNC coarse-thread hex head cap screw for use with Grade 2 compatible nuts, washers, and tapped holes in general construction and mechanical assemblies.

Installation Notes

Installation should be performed by a qualified tradesperson or mechanic using an appropriate socket or open-end wrench sized for the hex head. Ensure mating threads and tapped holes are clean and free of debris before installation. Do not exceed the load ratings associated with Grade 2 fasteners in high-stress or safety-critical structural applications where a higher grade may be specified by engineering design. Follow applicable building codes and fastener specifications for the project type.
