Value Collection 402328BR Hex Head Cap Screw 1-8x5 Grade 2

Product Description

The VALUE COLLECTION 402328BR is a partially threaded hex head cap screw designed for general-purpose fastening applications in mechanical, structural, and industrial assembly work. Manufactured from Grade 2 steel with a bright uncoated finish, this fastener measures 1-8 inch thread size with a 5-inch length under head. The UNC (Unified National Coarse) thread standard ensures wide compatibility with standard tapped holes and nuts. Measured by length under head, this screw suits applications where a defined grip length and unthreaded shank are required. Installation is typically performed by machinists, millwrights, maintenance technicians, or general tradespeople using standard hex wrenches or socket tools.

This fastener is suited for light-to-medium duty bolted connections in residential, commercial, and industrial settings. The coarse UNC thread pattern makes it well-suited for use in softer base materials and for applications requiring faster thread engagement. The uncoated bright finish is appropriate for indoor or dry environments where corrosion resistance is not a primary concern. It is commonly used in equipment assembly, jig and fixture work, and general mechanical fabrication where Grade 2 steel strength is sufficient.

Key Features

• 1-8 UNC thread size with 5-inch length under head for defined grip and shank clearance
• Partially threaded shank allows controlled clamping without thread engagement through the full grip length
• Grade 2 steel construction provides adequate strength for light-to-medium duty fastening
• Bright uncoated finish suitable for dry, indoor assembly environments
• UNC thread standard ensures compatibility with standard coarse-thread nuts and tapped holes
• Hex head drive accepts standard hex wrenches and socket sets

Compatibility

Designed as a standard UNC coarse-thread hex head cap screw for use with any 1-8 inch coarse-thread nut or tapped hole conforming to Unified National Coarse thread standards.

Installation Notes

Installation is performed using a standard hex socket or open-end wrench sized to the hex head. Always verify that the mating nut or tapped hole matches the 1-8 UNC thread specification before installation. Do not exceed the load ratings associated with Grade 2 steel in high-stress or safety-critical structural connections. Follow applicable mechanical codes and torque guidelines for the specific joint material and application.
