Value Collection 402324BR Hex Head Cap Screw 1-8x4 Grade 2

Product Description

The VALUE COLLECTION 402324BR is a 1-8 UNC hex head cap screw designed for general-purpose mechanical assembly and structural fastening applications. The fastener measures 4 inches under the head and features partial threading along the shank, which helps maintain clamping force across joined materials without thread engagement in the grip zone. Manufactured from Grade 2 steel with a bright, uncoated finish, this screw suits dry or indoor environments where corrosion resistance is not a primary requirement. It is a standard inch-series fastener installed by maintenance technicians, millwrights, and general contractors using conventional hand or power tools.

This hex head cap screw is suited for light-to-medium structural connections in residential construction, light industrial equipment, and general machinery assembly. The 1-8 UNC coarse thread pitch offers good resistance to cross-threading and is compatible with standard UNC tapped holes and nuts of the same thread designation. Partial threading makes it well-suited for through-bolt applications where a smooth shank provides bearing support between two clamped members.

Key Features

• 1-8 UNC coarse thread standard for broad tooling and nut compatibility
• Partially threaded shank provides clamping grip support in through-bolt installations
• Grade 2 steel construction meets minimum tensile requirements for general-purpose fastening
• Bright, uncoated finish suitable for indoor and dry-environment use
• 4-inch length under head accommodates moderate material stack thicknesses

Compatibility

Designed as a general-purpose UNC inch-series fastener for use with standard 1-8 UNC nuts, washers, and tapped holes in steel, wood, and similar substrates.

Installation Notes

Installation requires a standard hex wrench or socket driver sized for a 1-inch nominal fastener. Always ensure the mating tapped hole or nut matches the 1-8 UNC thread standard before driving. Torque to values appropriate for Grade 2 steel fasteners as specified by the applicable engineering standard or job specification. Do not use in applications requiring corrosion resistance without additional protective measures such as plating or coating.
