Value Collection MP30000 Hex Cap Screw 1/4-20 X 1/2 in Grade 5 50pk

Product Description

The VALUE COLLECTION MP30000 is a 1/4-20 x 1/2 inch hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. Fully threaded along its entire shank length, this fastener meets ASME B18.2.1 dimensional standards and uses a Unified National Coarse (UNC) thread form. The zinc coating provides baseline corrosion resistance suitable for general indoor and light outdoor applications. Sold in packs of 50, it is used by electricians, HVAC technicians, plumbers, and general tradespeople wherever a standard 1/4-20 hex drive fastener is required for panel mounting, bracket attachment, or equipment assembly.

This screw is suited for light-duty to medium-duty fastening tasks in residential and commercial trade applications. Common install scenarios include securing electrical enclosure covers, HVAC access panels, plumbing support brackets, and general sheet metal or structural steel assemblies where a fully threaded 1/4-20 fastener and standard hex wrench drive are appropriate. The 1/2 inch length under head is measured per ASME B18.2.1 convention.

Key Features

• Grade 5 steel construction for reliable tensile strength in general trade fastening applications
• Fully threaded shank provides maximum thread engagement for the 1/2 inch grip length
• Zinc-plated finish offers corrosion resistance for dry and light-duty environments
• UNC 1/4-20 thread form is one of the most common inch-series thread standards in the trades
• Meets ASME B18.2.1 dimensional standards for consistent sizing and interchangeability
• Pack of 50 reduces per-unit cost and supports job-site stock replenishment

Compatibility

Designed as a standard UNC inch-series hex head cap screw compatible with any 1/4-20 threaded hole or nut conforming to ASME B18.2.1 specifications.

Installation Notes

Install with a standard hex wrench, socket, or hex bit driver sized for a 1/4-20 hex head cap screw. Ensure the mating thread or nut is also rated for 1/4-20 UNC before installation. De-energize any electrical equipment and shut off fluid systems before accessing panels or enclosures where this fastener is used. Do not exceed the load rating appropriate for Grade 5 hardware in the specific application.
