Value Collection D30069 Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION D30069 is a 3/8-16 hex head cap screw measuring 5-1/2 inches in length under head, manufactured from Grade 5 steel with a zinc-plated finish. This partially threaded fastener conforms to ASME B18.2.1 standards and uses a UNC thread form. It is a general-purpose structural fastener suited for mechanical assemblies, equipment mounting, and industrial maintenance work. Installers in HVAC, plumbing, electrical, and general mechanical trades use this screw type when a heavy-hex or socket drive is not required and a standard wrench-driven fastener is the right call for the job.

This fastener is appropriate for use in residential and commercial applications where Grade 5 steel strength is specified. Partial threading makes it well suited for clamping applications where the unthreaded shank spans the joint interface, providing better shear resistance and a cleaner clamp load. It is a common replacement or stock-up fastener for service vans, maintenance shops, and equipment repair.

Key Features

• 3/8-16 UNC thread size with 5-1/2 inches length under head
• Grade 5 steel construction for medium-strength fastening requirements
• Zinc-plated finish for basic corrosion resistance in indoor and sheltered applications
• Partially threaded shank for improved shear resistance and clamping performance
• Conforms to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard inch-series hex head cap screw suitable for general mechanical, HVAC, plumbing, and electrical equipment assemblies requiring a 3/8-16 UNC thread pattern and Grade 5 steel strength classification.

Installation Notes

Install using an appropriately sized open-end, box-end, or socket wrench. Torque to the value specified by the equipment manufacturer for 3/8-16 Grade 5 fasteners in the applicable joint material. Power down or de-energize any equipment before accessing fastener locations near electrical components. Do not use in applications requiring Grade 8 or stainless steel where load, temperature, or corrosion conditions exceed the rated properties of this fastener.
