Value Collection 207571 Hex Head Cap Screw 1/4-20 X 2 in 18-8 Ss

Product Description

The VALUE COLLECTION 207571 is a fully threaded hex head cap screw in the 1/4-20 thread size with a 2-inch length under head, manufactured from 18-8 stainless steel. The 18-8 alloy provides solid corrosion resistance in both indoor and outdoor environments, making it a dependable fastener for general mechanical assembly, HVAC equipment mounting, plumbing fixture work, and light structural applications. The UNC (Unified National Coarse) thread form is the most widely used inch-series thread standard, compatible with standard tapped holes and nuts across trade applications. Licensed tradespeople and experienced DIYers can install this fastener using standard hex tooling.

This screw is suited for use in residential and light commercial applications where corrosion resistance is required and an inch-system fastener is specified. Typical use cases include equipment panel fastening, electrical enclosure assembly, plumbing bracket mounting, and HVAC unit hardware. The fully threaded shank ensures maximum thread engagement along the full 2-inch grip length, which is useful in thinner or stacked material assemblies where partial threading would reduce holding strength.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Fully threaded shank maximizes thread engagement for strong clamping force
• 1/4-20 UNC thread form fits standard inch-series tapped holes and nuts
• 2-inch length under head suits a wide range of stacked-material thicknesses
• Hex drive head is compatible with standard hex wrenches and socket tooling

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 1/4-20 UNC thread pattern and 2-inch fastener length in stainless steel.

Installation Notes

Installation requires a correctly sized hex wrench or socket driver; confirm the mating hole or nut is tapped to 1/4-20 UNC before installation. Do not cross-thread or overtighten, as stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when threading into stainless or aluminum tapped holes. Torque to the specification called out in the equipment or structural drawing for the application. Always power down or de-energize equipment before accessing internal fasteners on electrical or HVAC enclosures.
