Value Collection C703011 Hex Head Cap Screw 1/4-28 Grade 8

Product Description

The VALUE COLLECTION C703011 is a 1/4-28 UNF hex head cap screw designed for high-strength fastening applications. Measuring 1-1/4 inches under the head with partial threading, this fastener is manufactured from Grade 8 steel in an uncoated finish. Grade 8 steel provides a tensile strength rating suitable for demanding mechanical assemblies, making it a reliable choice for structural and industrial installations. It conforms to ASME B18.2.1 dimensional standards. Licensed tradespeople and experienced assemblers working on machinery, equipment frames, and structural sub-assemblies rely on this fastener where a standard-strength bolt is not sufficient.

This screw is suited for use in mechanical, industrial, and trade applications that require fine-thread engagement in ferrous or high-strength substrates. The 1/4-28 UNF thread pitch offers finer threads per inch than the standard UNC series, improving resistance to vibration loosening in environments subject to dynamic loads. Partial threading allows the unthreaded shank to bear shear loads, making it appropriate for lap joint and clearance-hole applications. Sold in a package of 100 units, this fastener is appropriate for shop stock, MRO replenishment, and production assembly use.

Key Features

• Grade 8 steel construction for high tensile strength in demanding fastening applications
• 1/4-28 UNF fine thread for improved vibration resistance over coarse-thread equivalents
• Partially threaded shank supports shear load bearing in clearance-hole installations
• Uncoated finish — compatible with additional field-applied coatings or used as-is in dry environments
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment
• Packaged in quantities of 100 for shop stock and production replenishment

Compatibility

Designed as an OEM-style replacement or shop-stock fastener for mechanical assemblies requiring a 1/4-28 UNF hex head cap screw in Grade 8 steel meeting ASME B18.2.1 specifications.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for a 1/4-28 fastener. Always verify that mating threads in the receiving component are clean, undamaged, and of compatible thread class before installation. Apply torque in accordance with the equipment manufacturer's specifications for Grade 8 fasteners at this diameter. Do not use impact tools without a torque-limiting setting, as over-torquing Grade 8 fasteners can cause thread stripping or fastener failure.
