Value Collection D30060 Hex Head Cap Screw 3/8-16 X 2-1/2 in

Product Description

The VALUE COLLECTION D30060 is a 3/8-16 UNC hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. It measures 2-1/2 inches under the head and features partial threading along the shank. Designed to ASME B18.2.1 standards, this fastener delivers reliable clamping strength in structural and mechanical assemblies. Machinists, millwrights, pipefitters, and general contractors rely on Grade 5 fasteners for moderate-strength bolting applications where a heat-treated carbon steel fastener is required but alloy-grade material is not specified.

This screw is suited for use in mechanical equipment mounting, structural framing connections, pipe support fabrication, HVAC equipment bases, and general industrial assembly. The partial thread configuration provides a smooth shank section that resists shear loads and allows for precise alignment in clearance holes before thread engagement. The zinc plating provides baseline corrosion resistance appropriate for indoor and light-duty outdoor installations.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard hex nuts and tapped components
• 2-1/2 inches under-head length with partial threading for shear-resistant installations
• Grade 5 steel construction meets medium-strength bolting requirements
• Zinc-plated finish provides corrosion resistance for general service environments
• Conforms to ASME B18.2.1 dimensional standards for consistent fit and interchangeability

Compatibility

Designed as a standard 3/8-16 UNC hex head cap screw per ASME B18.2.1, compatible with any 3/8-16 hex nut, flange nut, or tapped hole conforming to UNC inch-series thread standards.

Installation Notes

Install with a standard 9/16-inch hex wrench or socket driver. Torque to the value specified by the equipment manufacturer or applicable structural specification for Grade 5 fasteners at this diameter. Ensure mating threads are clean and free of debris before assembly. Do not substitute Grade 5 fasteners in joints where Grade 8 or higher is specified by the design engineer.
