Holo-krome 78032 Hex Socket Cap Screw 8-32 Unc Stainless

Product Description

The HOLO-KROME 78032 is a hex socket cap screw with an 8-32 UNC thread and a 3/4 inch length under the head. It is fully threaded and machined from 18-8 stainless steel with a bright, uncoated finish. The recessed 9/64 inch hex drive accepts a standard hex key or Allen-type driver. This fastener meets ASME B18.3 and ASTM F837 standards, making it appropriate for mechanical assemblies, equipment panels, and light structural connections where corrosion resistance is required. Machinists, maintenance technicians, and equipment fabricators are the typical installers.

This screw is suited for use in residential and commercial mechanical assemblies, HVAC equipment panels, electrical enclosures, pump housings, and similar applications where a flush, low-profile fastener head is needed. The 18-8 stainless steel construction provides good resistance to moisture, mild chemicals, and general corrosion, making it a common choice in wet or outdoor-adjacent environments. Full threading along the 3/4 inch shank allows engagement across the entire grip length.

Key Features

• 8-32 UNC thread for compatibility with standard tapped holes in that thread family
• Fully threaded shank at 3/4 inch length under head for maximum thread engagement
• 18-8 stainless steel construction for corrosion resistance in wet or outdoor-adjacent environments
• 9/64 inch hex socket drive accepts standard hex keys
• Bright uncoated finish with no plating to flake or delaminate
• Meets ASME B18.3 and ASTM F837 dimensional and material standards

Compatibility

Designed as an OEM-style replacement or standard-service hex socket cap screw for any application requiring an 8-32 UNC fully threaded fastener with a 3/4 inch length under the head.

Installation Notes

Install using a calibrated hex key or Allen driver sized to 9/64 inch to avoid rounding the socket drive. Ensure the mating tapped hole is clean and free of debris before threading. Do not use an impact driver on small-diameter cap screws, as this can shear the head or strip the socket. Follow applicable equipment manufacturer torque specifications for 8-32 stainless fasteners when reassembling safety-critical components.
