Value Collection 403194PR Hex Cap Screw 1/2-13 X 2-3/4 in Grade 2

Product Description

The VALUE COLLECTION 403194PR is a hex head cap screw designed for general-purpose fastening in mechanical, structural, and industrial applications. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this fastener features a 1/2-13 UNC thread size and measures 2-3/4 inches under the head. The partial threading leaves a smooth shank section near the head, which is appropriate for applications requiring precise clamping or shear load transfer. Installation requires a 3/4-inch hex key or wrench. Tradespeople, maintenance technicians, and fabricators working with bolted assemblies commonly specify this fastener type.

This screw is suited for light-to-moderate duty bolted connections in residential and commercial construction, equipment assembly, and maintenance work. The 1/2-13 UNC coarse thread profile threads quickly into tapped holes and standard nuts, making it a common choice for field assembly and repair situations where speed and availability matter. The zinc plating provides a basic barrier against moisture in dry to mildly humid environments.

Key Features

• 1/2-13 UNC coarse thread for fast engagement and wide compatibility with standard hardware
• Partial threading for accurate clamping and shear load transfer in bolted joints
• Grade 2 steel construction suitable for general-purpose, non-critical fastening
• Zinc-plated finish provides basic corrosion resistance in dry to mildly humid environments
• 3/4-inch hex drive for standard wrench or socket installation
• 2-3/4-inch length under head accommodates moderate stack-up thicknesses

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, flat washers, and lock washers in general mechanical and structural bolted assemblies.

Installation Notes

Installation is performed with a 3/4-inch open-end, box-end, or socket wrench. Always ensure mating threads are clean and free of debris before assembly. Do not exceed the torque rating appropriate for Grade 2 fasteners as specified in your project engineering documentation. For structural or safety-critical connections, verify that Grade 2 steel meets the load requirements of the application before use.
