Value Collection 307244BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 307244BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural connections. It features a 1-8 UNC thread size with a 5-inch length under head and is partially threaded for controlled clamping force. The screw is driven by a 5/8-inch hex key. Made from alloy steel with a black oxide finish, it meets ASTM A574 specifications, which define mechanical property requirements for socket cap screws used in demanding service conditions. Licensed tradespeople and precision fabricators use this fastener where torque capacity and material strength are critical.

This screw is suited for use in industrial machinery, heavy equipment, mold and die work, and structural assemblies where a flush or low-profile head is required. The partially threaded shank provides a bearing surface for precise alignment and joint clamping. The coarse 1-8 UNC thread engages quickly in through-hole or tapped applications and offers good resistance to cross-threading in field conditions. Machinists, millwrights, and maintenance technicians are the primary installers.

Key Features

• 1-8 UNC coarse thread for fast engagement and reliable clamping in tapped steel applications
• 5-inch length under head with partial threading for accurate shank alignment
• 5/8-inch hex drive socket for high-torque installation with standard hex keys or socket tooling
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection in precision assemblies

Compatibility

Designed as an OEM-style or replacement socket cap screw for applications requiring a 1-8 UNC thread form and ASTM A574-compliant alloy steel fastener.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 5/8-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before installation. Do not exceed the torque capacity of the fastener or the mating material. Follow applicable fastener standards and equipment manufacturer specifications when determining installation torque.
