Value Collection D30010 Hex Head Cap Screw 1/4-20 2-1/2 in

Product Description

The VALUE COLLECTION D30010 is a 1/4-20 hex head cap screw measuring 2-1/2 inches under the head, manufactured from Grade 5 steel with a zinc-plated finish. It features partial threading along the shank and conforms to ASME B18.2.1 dimensional standards. This fastener is suited for general mechanical assembly, structural connections, and equipment maintenance tasks across HVAC, plumbing, and electrical trade applications. Installation is performed using a standard hex wrench or socket driver. The zinc plating provides a baseline level of corrosion resistance for indoor and light-duty service environments.

This screw is used in a wide range of trade and industrial assembly applications where a Unified National Coarse thread fastener is required. The partial threading design allows for a smooth shank section, which is useful when fastening through clearance holes or when shear loading is a consideration. It is appropriate for residential and light commercial equipment installation and repair work where Grade 5 steel strength is specified.

Key Features

• 1/4-20 UNC thread size for compatibility with standard coarse-thread tapped holes and nuts
• 2-1/2 inch length under head for extended reach in deep clearance applications
• Grade 5 steel construction provides medium-strength tensile performance
• Zinc-plated finish offers baseline corrosion resistance for indoor and light-duty use
• Partially threaded shank for smooth-bore clearance hole applications
• Conforms to ASME B18.2.1 dimensional and tolerance standards

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw per ASME B18.2.1, suitable for use with any 1/4-20 tapped hole or compatible hex nut in general mechanical and trade assembly applications.

Installation Notes

Install using a properly sized socket, box wrench, or hex driver. Ensure the mating tapped hole or nut is clean and free of debris before threading. Always power down or de-energize equipment before fastening or removing hardware on electrical or mechanical assemblies. Do not exceed the rated torque range for Grade 5 1/4-20 fasteners as specified by the equipment manufacturer or applicable trade code.
