Value Collection MP30056 Hex Cap Screw 3/8-16 X 1-1/2 in Grade 5

Product Description

The VALUE COLLECTION MP30056 is a hex head cap screw sized 3/8-16 x 1-1/2 inches, manufactured from Grade 5 steel with a zinc-plated finish. It features partial threading and conforms to ASME B18.2.1 standards. The Unified National Coarse (UNC) thread form makes it a standard choice for general mechanical assemblies across HVAC equipment, plumbing fixtures, electrical enclosures, and structural fastening applications. Each package contains 25 screws, making this a practical stocking item for service vehicles and shop inventory. The zinc plating provides a baseline level of corrosion resistance suitable for indoor and semi-protected environments.

This fastener is suited for use in a wide range of trade applications where a reliable, standardized hex cap screw is required. It is commonly used when assembling equipment frames, mounting brackets, access panels, and mechanical components in residential and light commercial settings. The 3/8-16 UNC thread size is one of the most frequently encountered fastener sizes in HVAC, plumbing, and electrical work, making this a practical addition to any technician's parts supply.

Key Features

• Grade 5 steel construction for reliable tensile strength in standard mechanical assemblies
• Zinc-plated finish provides corrosion resistance for indoor and semi-protected installations
• Partial threading per ASME B18.2.1 for precise clamping in standard fastening applications
• 3/8-16 UNC thread form — one of the most common sizes across HVAC, plumbing, and electrical trades
• 1-1/2 inch length under head suits a broad range of bracket and panel mounting depths
• Sold in a 25-piece package, convenient for restocking service kits and shop bins

Compatibility

Designed as a standard 3/8-16 UNC hex head cap screw suitable for general mechanical fastening applications in HVAC, plumbing, electrical, and related trade work where Grade 5 steel and ASME B18.2.1 compliance are required.

Installation Notes

Install using a standard hex wrench or socket drive sized for a 3/8-16 hex head cap screw. Always de-energize electrical equipment and isolate mechanical systems before disassembly or fastener replacement. Apply torque consistent with Grade 5 fastener guidelines for the specific joint material — do not over-torque into soft substrates such as aluminum or plastic housings. Follow applicable codes including NFPA 70 for electrical enclosures or IFGC guidelines for gas equipment assemblies where fastener integrity is a safety factor.
