Value Collection 97301 Hex Head Cap Screw 1/4-28 X 5/8 in Grade 5

Product Description

The VALUE COLLECTION 97301 is a fully threaded hex head cap screw engineered to Inch system standards. It features a 1/4-28 UNF thread size with a 5/8-inch length under head, manufactured from Grade 5 steel in an uncoated finish. This fastener meets ASME B18.2.1 dimensional standards, making it a reliable choice for precision mechanical assemblies, equipment maintenance, and general industrial fastening applications. It is installed by HVAC technicians, plumbers, electricians, and maintenance professionals wherever a fine-thread hex head fastener is required. Sold in packs of 100, this screw suits both job-site stock and routine service calls.

This screw is suited for applications requiring a fine unified thread (UNF) engagement, commonly found in tapped metal components, brackets, equipment housings, and mechanical assemblies across residential and commercial trade work. The Grade 5 steel construction provides adequate tensile strength for medium-duty clamping loads. The uncoated finish is appropriate for interior or dry-environment use where corrosion resistance is not a primary concern.

Key Features

• 1/4-28 UNF fully threaded profile for strong fine-thread engagement in metal substrates
• Grade 5 steel construction offers reliable tensile strength for medium-duty fastening

Compatibility

Designed as a standard ASME B18.2.1 Inch-series hex head cap screw compatible with any tapped or through-hole application requiring a 1/4-28 UNF thread pattern.

Installation Notes

Install using a standard hex wrench or socket driver sized for a 1/4-inch hex head cap screw. Ensure the mating tapped hole is clean and free of debris before driving. Do not overtighten in soft or thin metal substrates. Follow applicable equipment manufacturer torque guidelines where specified in service documentation.
