Value Collection 403122PR Hex Head Cap Screw 3/8-16x3in

Product Description

The VALUE COLLECTION 403122PR is a 3/8-16 x 3 inch partially threaded hex head cap screw manufactured from Grade 2 steel with a zinc-plated finish. Designed for general-purpose fastening applications, this UNC-threaded fastener provides reliable mechanical joining in light- to medium-duty assemblies. The zinc plating offers basic corrosion resistance suitable for indoor and mildly exposed environments. The 9/16-inch hex key size allows installation with standard wrenches and sockets. Tradespeople, maintenance technicians, and mechanical assemblers commonly use this fastener for equipment mounting, structural bracketing, and general mechanical work where high-strength grades are not required.

This hex head cap screw is suited for residential and light commercial mechanical assemblies, HVAC equipment mounting, plumbing fixture bracketing, electrical enclosure hardware, and general maintenance tasks. The partial threading allows the unthreaded shank to bear shear loads and align mating components before the threaded section engages the nut or tapped hole. It is a standard inch-series fastener compatible with any 3/8-16 UNC tapped hole or standard hex nut of the same thread specification.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard nuts and tapped holes
• 3-inch length under head for fastening thicker assemblies or when additional grip length is needed
• Partial threading allows the shank to carry shear loads and aid component alignment
• Grade 2 steel construction suitable for light- to medium-duty general fastening
• Zinc-plated finish provides basic corrosion resistance for indoor and mildly exposed installations
• 9/16-inch hex drive compatible with standard wrenches and socket sets

Compatibility

Compatible with any standard 3/8-16 UNC tapped hole or hex nut. Suitable as a general-purpose replacement or stock fastener wherever a Grade 2 steel, zinc-plated, partially threaded 3/8-16 x 3 inch hex head cap screw is specified.

Installation Notes

Install using a standard 9/16-inch wrench or socket. Ensure the mating tapped hole or nut is clean and free of debris before threading. Do not overtighten, as Grade 2 fasteners have lower proof load ratings than Grade 5 or Grade 8 hardware. Follow applicable mechanical or structural codes when using fasteners in load-bearing or safety-critical assemblies.
