Value Collection R82222382 Hex Head Cap Screw 1/2-20

Product Description

The VALUE COLLECTION R82222382 is a 1/2-20 UNF hex head cap screw machined from 18-8 stainless steel and left uncoated for a clean, corrosion-resistant finish. It measures 1-3/4 inches under the head and uses a fine-thread UNF profile, which provides greater tensile strength per thread engagement compared to coarse-thread fasteners. This fastener is installed by HVAC technicians, plumbers, electricians, millwrights, and general tradespeople wherever a durable, corrosion-resistant hex cap screw is required in mechanical assemblies or structural connections.

The R82222382 is suited for applications where corrosion resistance is a priority, including outdoor equipment enclosures, wet mechanical rooms, pool equipment panels, and marine-adjacent installations. The 18-8 stainless steel grade resists oxidation and mild chemical exposure, making it a common choice for trade installations that cannot tolerate rust migration onto adjacent components. It is sold individually and is compatible with standard 1/2-20 UNF threaded holes and nuts.

Key Features

• 1/2-20 UNF fine-thread profile for higher thread engagement strength
• 1-3/4 inch length under head for precise fitment in standard mechanical assemblies
• 18-8 stainless steel construction provides corrosion and oxidation resistance
• Uncoated finish eliminates coating delamination concerns in wet or chemical environments
• Meets MS 35308-414D standard for dimensional and material compliance
• Sold as a single unit with no minimum order quantity beyond one piece

Compatibility

Designed as a standard 1/2-20 UNF hex head cap screw for use in any application requiring an inch-system fine-thread fastener in that size. Conforms to MS 35308-414D dimensional standards.

Installation Notes

Install using a standard hex wrench or socket driver sized for a 1/2-inch hex head cap screw. Ensure the mating threaded hole or nut is also 1/2-20 UNF to avoid cross-threading. De-energize or depressurize any equipment before fastener service, following applicable NEC, IPC, or IFGC requirements for the system being serviced. Applying a small amount of anti-seize compound to stainless fastener threads is a common field practice to prevent galling during installation.
