Value Collection 403150PR Hex Cap Screw 7/16-14 X 1-3/4 in Grade 2

Product Description

The VALUE COLLECTION 403150PR is a partially threaded hex head cap screw designed for general mechanical fastening applications. It is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in dry to mildly humid environments. The fastener measures 7/16-14 thread size with a 1-3/4 inch length under the head and follows the Unified National Coarse (UNC) thread standard. A 5/8-inch hex key size is required for installation. This screw is a standard choice for light- to medium-duty structural and mechanical assemblies across HVAC, plumbing, electrical, and general trade work.

This cap screw is suited for use in residential and light commercial applications where a reliable, standardized inch-series fastener is needed. Partial threading allows for a smooth shank section near the head, which is useful when clamping two components together without thread engagement through the full grip length. Typical uses include equipment panels, brackets, mounting hardware, and general machinery assembly where Grade 2 steel strength is adequate for the load requirements.

Key Features

• 7/16-14 UNC thread for broad compatibility with standard inch-series tapped holes
• Partially threaded shank provides a smooth grip zone for clamping applications
• Grade 2 steel construction suitable for light- to medium-duty fastening
• Zinc-plated finish offers basic protection against corrosion in dry environments
• 1-3/4 inch length under head accommodates moderate material stack-ups
• 5/8-inch hex drive size compatible with standard wrenches and sockets

Compatibility

Designed for use in any application requiring a 7/16-14 UNC partially threaded hex head cap screw in an inch-series measurement system. Fits standard tapped holes or hex nuts conforming to UNC 7/16-14 thread specifications.

Installation Notes

Installation requires a 5/8-inch open-end, box, or socket wrench. Ensure mating threads are clean and free of debris before installation. Do not exceed the load ratings appropriate for Grade 2 steel in structural or safety-critical applications. Follow applicable mechanical codes and equipment manufacturer torque guidance for the specific assembly.
