Value Collection MP30179 Hex Head Cap Screw 1/4-28 X 1 in

Product Description

The VALUE COLLECTION MP30179 is a 1/4-28 UNF fully threaded hex head cap screw designed for secure mechanical fastening in trade and industrial applications. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers solid tensile strength and corrosion resistance suitable for general-purpose assembly work. The 1 inch length under head and fine-thread UNF profile make it well suited for applications requiring precise clamping force and vibration resistance. Each package contains 50 screws, conforming to ASME B18.2.1 dimensional standards.

This fastener is commonly used in HVAC equipment assembly, electrical panel and bracket mounting, plumbing fixture installation, and general mechanical assembly where a 1/4-28 fine-thread fastener is specified. The zinc plating provides a base level of corrosion protection appropriate for indoor and sheltered environments. Installers working on sheet metal enclosures, motor mounts, access panels, and similar light structural connections will find this screw a standard fit for those applications.

Key Features

• 1/4-28 UNF fine thread for precise clamping and vibration resistance
• 1 inch length under head, fully threaded along the entire shank
• Grade 5 steel construction for reliable tensile and shear strength
• Zinc-plated finish for corrosion resistance in sheltered environments
• Meets ASME B18.2.1 dimensional standards
• Sold in a 50-piece package for job-site and shop use

Compatibility

Designed as a standard 1/4-28 UNF hex head cap screw for use wherever ASME B18.2.1 compliant inch-system fasteners are required in mechanical, HVAC, electrical, or plumbing assembly applications.

Installation Notes

Installation is performed using a standard hex wrench or socket driver sized for a 1/4-28 hex head fastener. Always de-energize and lock out equipment before fastening or removing hardware on electrical or mechanical systems. Follow applicable codes and equipment manufacturer torque guidelines for the specific assembly. Inspect the zinc-plated finish prior to installation and avoid use in continuously wet or chemically exposed environments where a higher-grade coating may be required.
