Value Collection R57001112 1/4-28 X 1 in Hex Cap Screw Ss

Product Description

The VALUE COLLECTION R57001112 is a fully threaded hex head cap screw designed for secure mechanical fastening in precision and general-purpose applications. Machined to a 1/4-28 UNF thread specification with a 1-inch length under head, this fastener is manufactured from 18-8 stainless steel and left uncoated to preserve its natural corrosion resistance. The 18-8 alloy provides reliable resistance to oxidation and mild chemicals, making it a practical choice where a finished or galvanized fastener would be unsuitable. HVAC, plumbing, electrical, and pool service technicians commonly reach for UNF-thread stainless fasteners when securing equipment panels, brackets, and component assemblies.

This fastener is suited for installations requiring a fine-thread engagement in thin-gauge metal, aluminum, or stainless components. Fully threaded construction maximizes thread engagement along the entire grip length, which is beneficial when fastening into shallow threaded holes or when using a nut along the full shank. Typical applications include equipment enclosure assembly, condensing unit panel fastening, pump bracket hardware, and control-board mounting in environments where moisture or chemical exposure rules out carbon-steel hardware.

Key Features

• 1/4-28 UNF fine thread for precise engagement in metal and threaded inserts
• Fully threaded along the entire 1-inch length under head
• 18-8 stainless steel construction provides corrosion resistance without a surface coating
• Uncoated finish eliminates coating thickness variability in tight-tolerance applications
• Inch measurement system; length measured under head per standard convention

Compatibility

Designed as a standard 1/4-28 UNF hex head cap screw for use in any application requiring an inch-series fine-thread fastener in that size and grade.

Installation Notes

Install using the appropriate hex driver or wrench for a 1/4-inch hex head cap screw. Ensure mating threads are clean and free of debris before assembly. When installing in stainless-to-stainless applications, apply an anti-seize compound to prevent galling. Always de-energize equipment and follow applicable safety lockout procedures before replacing or installing fasteners on live assemblies.
