Value Collection 307148BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 307148BR is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. Built from alloy steel with a black oxide coating, this screw provides reliable clamping force and moderate corrosion resistance in demanding environments. It features a 5/8-11 UNC thread size with a 4.5-inch length under head and is partially threaded, making it well suited for applications where thread engagement must be controlled. Drive interface is a 1/2-inch internal hex socket. The part meets ASTM A574 standards for alloy steel socket cap screws.

This cap screw is used in a wide range of mechanical and industrial applications including machine frames, tooling fixtures, hydraulic components, and structural assemblies. It is appropriate for both shop fabrication and field service work where a high-strength socket head fastener is required. The partially threaded shank allows the unthreaded portion to bear shear loads while the threaded section provides secure clamping. Machinists, millwrights, maintenance technicians, and industrial tradespeople are the primary installers of this hardware type.

Key Features

• 5/8-11 UNC thread size for use with standard unified coarse-thread nuts and tapped holes
• 4.5-inch length under head provides extended grip range for thick material stacks
• Partially threaded shank supports shear load distribution in precision assemblies
• 1/2-inch hex socket drive for use with standard hex keys and socket drivers
• Alloy steel construction meets ASTM A574 for high-tensile socket cap screw service
• Black oxide finish provides mild corrosion resistance and reduced light reflection

Compatibility

Designed as a standard ASTM A574 alloy steel hex socket cap screw compatible with 5/8-11 UNC tapped holes and corresponding hex nuts in industrial and mechanical fastening applications.

Installation Notes

Installation typically requires a 1/2-inch hex key or socket drive tool. Always ensure the mating tapped hole or nut meets the appropriate thread class and material strength before assembly. Power down or de-energize any equipment before accessing fastener locations on live machinery. Do not use impact tools at full torque without a torque-limiting setting, as over-driving socket cap screws can cause thread stripping or fastener failure.
