Value Collection 592505BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 592505BR is a hex socket cap screw designed for high-strength fastening in structural, mechanical, and industrial assemblies. It features a 1-8 UNC thread size with a 4.5-inch length under head and is driven by a 3/4-inch hex key. Manufactured from 18-8 austenitic stainless steel with a bright, uncoated finish, this fastener offers solid corrosion resistance and is suitable for applications where appearance and surface integrity matter. The partial threading configuration provides a smooth shank section for improved shear strength and precise clamping force.

This cap screw is suited for use in general manufacturing, equipment fabrication, and maintenance applications where a recessed hex drive is preferred for flush or countersunk installation. The 1-8 UNC coarse thread pattern provides reliable engagement in tapped holes and is a common thread form across a wide range of mechanical assemblies. Installation is typically performed by machinists, millwrights, or maintenance technicians working in industrial or commercial settings.

Key Features

• 1-8 UNC coarse thread for broad compatibility with standard tapped holes
• 4.5-inch length under head with partial threading for shear load capability
• 3/4-inch hex socket drive for secure torque application with a hex key or socket tool
• 18-8 austenitic stainless steel construction per ASTM F837 for corrosion resistance
• Bright, uncoated finish maintains dimensional tolerances and surface appearance
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as a standard hex socket cap screw replacement for assemblies requiring a 1-8 UNC thread, 4.5-inch length under head, and 3/4-inch hex drive in stainless steel construction.

Installation Notes

Installation should be performed by a qualified mechanic or technician using a calibrated hex key or socket drive sized to 3/4 inch. Ensure the tapped hole is clean and free of debris before threading to avoid galling, which is a common risk with stainless steel fasteners. Apply an anti-seize compound appropriate for stainless steel threads to reduce galling risk during installation and future removal. Always verify thread engagement depth meets the requirements of the assembly before applying full torque.
