Value Collection MP30177 Hex Head Cap Screw 1/4-28 X 3/4 in

Product Description

The VALUE COLLECTION MP30177 is a fully threaded hex head cap screw sized 1/4-28 x 3/4 inches, manufactured from Grade 5 steel with a zinc-plated finish. This fastener meets ASME B18.2.1 standards and features a Unified National Fine (UNF) thread form, making it a reliable choice for close-tolerance mechanical assemblies. The zinc plating provides a base level of corrosion resistance for general-purpose applications. Packaged in quantities of 50, these screws are well suited for shops, field service kits, and maintenance operations where consistent hardware stock is essential. Installed using standard hand tools or power drivers with the appropriate hex socket or wrench.

This screw is appropriate for use in residential and light commercial mechanical assemblies where a 1/4-28 UNF fastener is specified. Common installation scenarios include securing sheet metal components, brackets, motor mounts, control board housings, and similar hardware found in HVAC equipment, electrical enclosures, and plumbing fixtures. The fully threaded shank provides maximum thread engagement across the full 3/4-inch length under the head, which is useful when fastening thin material stacks or when a nut and washer are used on the opposite side.

Key Features

• 1/4-28 UNF thread for fine-pitch engagement in close-tolerance assemblies
• Fully threaded shank maximizes thread engagement along the full 3/4-inch length under head
• Grade 5 steel construction provides solid tensile strength for general mechanical fastening
• Zinc-plated finish offers baseline corrosion resistance in interior and protected environments
• Conforms to ASME B18.2.1 dimensional standards
• Sold in packs of 50 for shop stock and field service use

Compatibility

Designed as a general-purpose 1/4-28 UNF hex head cap screw suitable for use wherever ASME B18.2.1 inch-series fasteners are specified in mechanical, HVAC, electrical, or plumbing assemblies.

Installation Notes

Installation requires a standard 7/16-inch hex wrench or socket driver. De-energize any electrical equipment and shut off fluid or gas supply before replacing fasteners on live systems. Do not exceed the torque rating appropriate for Grade 5 hardware at this thread size as published in standard torque reference charts. Zinc-plated fasteners are intended for dry or protected interior environments and should not be substituted in applications requiring stainless or hot-dip galvanized hardware.
