Holo-krome 79020 Hex Socket Cap Screw 10-32 Unf Stainless

Product Description

The HOLO-KROME 79020 is a hex socket cap screw designed for secure, high-torque fastening in tight-clearance applications. It features a 10-32 UNF thread pattern and a 1/2 inch length under head, with full threading from head to tip. The 5/32 inch hex drive accepts a standard Allen-type key. Constructed from 18-8 stainless steel with a bright, uncoated finish, it resists corrosion in wet or chemically exposed environments. This fastener meets ASME B18.3 and ASTM F837 standards, making it suitable for precision mechanical assemblies, HVAC equipment panels, plumbing fixtures, and electrical enclosures requiring dimensional consistency and material traceability.

The HOLO-KROME 79020 is commonly used in light industrial, commercial, and residential trade applications where a compact, recessed-drive fastener is required. Typical install scenarios include mounting components inside HVAC unit enclosures, securing control board brackets, assembling plumbing manifolds, and attaching electrical panel hardware. The fully threaded shank provides uniform clamping force across the full grip length, which is particularly useful when joining thin material stacks. Trade professionals in HVAC, plumbing, and electrical work reach for this screw when stainless corrosion resistance and a clean, uncoated finish are specified.

Key Features

• 10-32 UNF thread for fine-pitch engagement and vibration resistance
• Fully threaded shank for maximum clamping across thin material stacks
• 5/32 inch hex socket drive for use with standard Allen keys or hex bits
• 18-8 stainless steel construction for corrosion resistance in wet or chemically exposed settings
• Bright uncoated finish maintains dimensional tolerances without coating buildup
• Meets ASME B18.3 and ASTM F837 fastener standards

Compatibility

Designed as an OEM-style replacement or service fastener for any assembly specifying a 10-32 UNF hex socket cap screw with a 1/2 inch length under head in 18-8 stainless steel per ASME B18.3.

Installation Notes

Installation is performed with a 5/32 inch hex key or Allen-type driver bit. De-energize and lock out all electrical circuits and shut off fluid supply lines before servicing any assembly that requires fastener replacement. Apply appropriate thread engagement depth per the mating material to avoid stripping fine UNF threads. Do not mix stainless fasteners with dissimilar metals in environments where galvanic corrosion is a concern.
