Value Collection MP30060 Hex Cap Screw 3/8-16 X 2-1/2 in Grade 5

Product Description

The VALUE COLLECTION MP30060 is a 3/8-16 x 2-1/2 inch hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. It features partial threading and conforms to ASME B18.2.1 standards, making it a reliable choice for structural and mechanical fastening applications. The Unified National Coarse (UNC) thread form provides strong thread engagement in standard tapped holes. Length is measured under the head. This fastener is used by maintenance technicians, pipefitters, millwrights, and general tradespeople across a range of industrial and commercial installations.

This hex cap screw is suited for bolted connections in equipment mounting, mechanical assemblies, pipe supports, panel framing, and general structural fastening. Partial threading makes it appropriate for applications requiring a grip length through unthreaded material before engaging a nut or tapped hole. It is commonly used in HVAC equipment mounting, plumbing support structures, and electrical panel and conduit support fabrication where a 3/8-16 UNC fastener is specified.

Key Features

• 3/8-16 UNC thread size with 2-1/2 inch length under head
• Grade 5 steel construction for medium-strength bolted joint applications
• Zinc-plated finish provides basic corrosion resistance in dry or mildly humid environments
• Partially threaded shank for grip-length applications requiring an unthreaded body
• Conforms to ASME B18.2.1 dimensional standards
• Sold in a 25-piece package to support job-lot usage

Compatibility

Designed for use in any application requiring a 3/8-16 UNC hex head cap screw with a 2-1/2 inch length under head, conforming to ASME B18.2.1 dimensional requirements.

Installation Notes

Install using a standard hex wrench, socket set, or impact driver with the appropriate 9/16 inch fastener drive. Verify that mating threads or nuts are also 3/8-16 UNC to avoid cross-threading. Torque to the value specified by the equipment manufacturer or applicable structural standard for Grade 5 fasteners. Do not use zinc-plated fasteners in submerged, high-humidity, or outdoor weather-exposed applications without verifying corrosion resistance requirements.
