Value Collection MP30064 Hex Cap Screw 3/8-16 X 3-1/2 in Grade 5

Product Description

The VALUE COLLECTION MP30064 is a 3/8-16 x 3-1/2 inch hex head cap screw 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. The Unified National Coarse (UNC) thread form provides reliable clamping force in general fastening applications. This screw is sized by length under head and is sold in a package of 10. It is a standard hardware item installed by mechanical contractors, HVAC technicians, plumbers, electricians, and maintenance professionals across a wide range of trade and industrial applications.

This hex head cap screw is suited for structural and mechanical fastening tasks in residential and commercial trade work. The partially threaded shank makes it appropriate for through-bolting applications where a smooth shank section is needed to bear shear loads or allow proper clamping between two members. The zinc plating provides basic corrosion resistance for indoor and moderate-exposure environments. Common uses include equipment mounting, bracket installation, and panel fastening across HVAC, plumbing, and electrical trades.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard hex nuts and tapped holes
• 3-1/2 inch length under head — partially threaded shank for shear-load and through-bolt applications
• Grade 5 steel construction provides medium-strength clamping performance
• Zinc-plated finish offers basic corrosion resistance in indoor and low-moisture environments
• Conforms to ASME B18.2.1 dimensional standard for consistent fit and interchangeability
• Sold in a 10-piece package for small-quantity job or service use

Compatibility

Designed for use with standard 3/8-16 UNC hex nuts, lock nuts, and tapped holes conforming to inch-series thread standards. Compatible with general mechanical and structural fastening applications across HVAC, plumbing, electrical, and maintenance trades.

Installation Notes

Install with a standard hex wrench or socket drive sized for a 3/8-16 hex head cap screw. Ensure mating threads are clean and undamaged before installation. Do not exceed the rated torque range for Grade 5 fasteners as specified in applicable mechanical or equipment codes. Zinc-plated fasteners are not recommended for outdoor or high-moisture environments where a higher corrosion-resistance finish would be required.
