Value Collection MP39302 Hex Cap Screw 1/4-28 X 3/4 in Grade 8

Product Description

The VALUE COLLECTION MP39302 is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, industrial, and trade service work. Built to Grade 8 steel specifications, this fastener delivers superior tensile strength compared to lower-grade alternatives, making it appropriate for high-load assemblies and vibration-prone environments. The zinc yellow dichromate finish provides corrosion resistance while serving as a visual identifier for Grade 8 classification. Thread size is 1/4-28 UNF with a 3/4-inch length under head, conforming to ASME B18.2.1 dimensional standards. Sold in a package of 50 pieces.

This fastener is suited for use in precision mechanical assemblies, equipment repair, and structural connections where fine-thread engagement and high clamping force are required. The 1/4-28 UNF thread pitch is common in automotive, HVAC equipment frames, electrical enclosures, and light industrial machinery. Licensed tradespeople and maintenance technicians installing or servicing equipment will find this screw appropriate for applications demanding a standardized, torque-rated fastener with documented material grade and finish.

Key Features

• Zinc yellow dichromate finish for corrosion resistance and grade identification
• Fully threaded shank along the 3/4-inch length under head
• 1/4-28 UNF fine thread for improved fastening torque and vibration resistance
• Meets ASME B18.2.1 dimensional standards for hex head cap screws
• Packaged in quantities of 50 for service stock and job-site use

Compatibility

Designed as a standard 1/4-28 UNF hex head cap screw conforming to ASME B18.2.1, suitable for any application specifying a Grade 8 fastener in that thread size and length.

Installation Notes

Installation should be performed by a qualified technician familiar with proper fastener torque procedures for Grade 8 hardware. Always verify thread engagement and mating material compatibility before installation. Use a calibrated torque wrench to achieve the specified clamp load for the joint design. Do not mix Grade 8 fasteners with lower-grade nuts or threaded inserts that are not rated for equivalent load.
