Value Collection D30233 Hex Head Cap Screw 3/8-24 X 2 in

Product Description

The VALUE COLLECTION D30233 is a 3/8-24 UNF hex head cap screw designed for applications requiring a fine-thread fastener with reliable clamping strength. Manufactured from Grade 5 steel with a zinc-plated finish, this screw measures 2 inches under the head and is partially threaded along its shank. The zinc plating provides a baseline level of corrosion resistance suitable for general indoor and light-duty mechanical assemblies. Licensed trades and maintenance professionals working in HVAC, plumbing, electrical, and equipment service will find this fastener meets ASME B18.2.1 dimensional standards for hex head cap screws.

This screw is suited for residential and light commercial mechanical assemblies where fine-thread engagement is required. The 3/8-24 UNF thread profile provides tighter thread pitch than its coarse-thread counterpart, making it appropriate for applications where vibration resistance or precise torque control is important. Partial threading allows the unthreaded shank to act as a locating or bearing surface in certain joint configurations, which is common in equipment mounting and bracket attachment applications.

Key Features

• 3/8-24 UNF fine thread for improved vibration resistance compared to coarse-thread equivalents
• Grade 5 steel construction for moderate-strength fastening requirements
• Zinc-plated finish for basic corrosion protection in dry and light-moisture environments
• Partially threaded shank for use as a locating or bearing surface in joint assemblies
• Meets ASME B18.2.1 dimensional standards for hex head cap screws
• Standard hex head accepts common wrenches and sockets for straightforward installation

Compatibility

Designed as a general-purpose replacement or service fastener for equipment and assemblies requiring a 3/8-24 UNF hex head cap screw with a 2-inch length under head and partial threading per ASME B18.2.1.

Installation Notes

Install using an appropriately sized hex wrench or socket drive. Always confirm the mating thread is 3/8-24 UNF before installation to avoid cross-threading. Apply thread torque per the equipment manufacturer's specification for Grade 5 fasteners in the applicable joint material. Replace any screw that shows thread damage, corrosion, or deformation during inspection.
