Holo-krome 78018 Hex Socket Cap Screw 6-32 Unc Stainless

Product Description

The HOLO-KROME 78018 is a hex socket cap screw designed for secure, high-torque fastening in applications where a standard hex head is not practical. Featuring a 6-32 UNC thread and a 3/8-inch length under head, this screw is fully threaded and driven with a 7/64-inch hex key. Constructed from 18-8 stainless steel with a bright uncoated finish, it provides solid corrosion resistance in environments exposed to moisture or mild chemicals. It meets ASME B18.3 and ASTM F837 fastener standards, making it suitable for precision assemblies, machine components, and control panel hardware.

This screw is commonly used in light mechanical assemblies, electrical enclosures, instrumentation panels, and HVAC control components where small-diameter, socket-drive fasteners are required. The 6-32 UNC thread is a widely used coarse thread for this screw size, compatible with standard 6-32 tapped holes in metal and hard plastic. Installers working on panel fabrication, equipment maintenance, or component mounting will find this fastener fits standard hardware layouts without modification.

Key Features

• 6-32 UNC thread for compatibility with standard tapped holes in metal and hard plastic
• Fully threaded 3/8-inch length under head maximizes thread engagement in thin material
• 7/64-inch hex socket drive for use with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction for corrosion resistance in wet or chemically active environments
• Bright uncoated finish — no plating that can flake or interfere with tight-tolerance fits
• Meets ASME B18.3 and ASTM F837 standards for dimensional and mechanical compliance

Compatibility

Designed as a standard 6-32 UNC hex socket cap screw suitable for any application requiring an ASME B18.3-compliant fastener in that thread size and length.

Installation Notes

Installation requires a 7/64-inch hex key or ball-end Allen driver. Ensure the mating tapped hole is clean and free of debris before threading to avoid galling, which is a common risk with stainless steel fasteners. Apply appropriate anti-seize compound if repeated removal is expected. Follow applicable mechanical assembly codes and torque guidelines for 6-32 stainless fasteners as specified by the equipment manufacturer.
