Value Collection 30071 Hex Head Cap Screw 3/8-16 X 6-1/2 in 25pk

Product Description

The VALUE COLLECTION 30071 is a partially threaded hex head cap screw designed for general mechanical fastening applications across trade and industrial environments. Built to Grade 5 steel specifications and finished with a zinc plating for corrosion resistance, this fastener meets ASME B18.2.1 and SAE J429 standards. The 3/8-16 UNC thread pattern and 6-1/2-inch length under head make it suitable for through-bolting structural assemblies, equipment mounting, and mechanical connections where a longer grip length is required. Sold in packs of 25, this screw is a standard choice for HVAC equipment installation, plumbing support structures, and general mechanical assembly work.

This fastener is appropriate for residential and commercial trade applications where UNC-threaded fasteners are specified. Common install scenarios include securing HVAC equipment brackets, condenser mounting frames, pipe support hardware, and electrical enclosure structures. The partial threading provides a smooth shank section that resists shear loads and allows for precise clamping without thread engagement through the full grip length. Technicians across HVAC, plumbing, and electrical trades regularly use Grade 5 zinc-plated hardware in these environments.

Key Features

• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish provides basic corrosion resistance for indoor and sheltered outdoor use
• Partially threaded shank supports shear loads and clean clamping
• 3/8-16 UNC thread for compatibility with standard inch-system nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standards for hex head cap screws
• Sold in a pack of 25 for stocking and repeat-use applications

Compatibility

Designed for use with standard 3/8-16 UNC nuts, washers, and tapped components conforming to inch-system thread standards. Suitable as a general-purpose fastener in mechanical, HVAC, plumbing, and electrical support assembly applications.

Installation Notes

Install using an appropriately sized hex wrench or socket drive rated for Grade 5 fastener torque ranges per applicable industry standards. Ensure mating threads are clean and free of debris before assembly. When used in outdoor or high-moisture environments, consider additional corrosion protection beyond the zinc plating. De-energize and isolate equipment per NFPA 70E or applicable safety codes before fastening near electrical components.
