Value Collection R40684204 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R40684204 is a hex socket cap screw engineered for fastening applications that demand corrosion resistance and reliable clamping force. Machined from 18-8 stainless steel, this fastener features a 1/4-20 UNC thread and a 3.5-inch length under head. Drive engagement is provided by a 3/16-inch hex socket, compatible with standard Allen keys and hex bit drivers. The 18-8 stainless steel construction provides solid resistance to oxidation and mild chemical exposure, making it well suited for installations in humid or outdoor-adjacent environments.

This cap screw is used in light to medium-duty mechanical assemblies across HVAC equipment, plumbing fixtures, electrical enclosures, and general industrial applications. The 1/4-20 UNC thread is one of the most common coarse-thread sizes in trade work, and the 3.5-inch length under head accommodates fastening through moderate material stack-ups. Technicians and assemblers working with sheet metal panels, equipment housings, or structural brackets will find this a standard-duty replacement or new-installation fastener.

Key Features

• 18-8 stainless steel construction resists corrosion in humid and mildly corrosive environments
• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 3/16-inch hex socket drive for use with Allen keys or hex bit drivers
• 3.5-inch length under head accommodates deeper fastening through stacked materials
• UNSPSC Code 31161501 for procurement and catalog classification

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use wherever a 1/4-20 coarse-thread fastener with a 3/16-inch hex drive is specified.

Installation Notes

Installation requires a 3/16-inch hex key or appropriately sized hex bit driver. Ensure the receiving thread is clean and free of debris before driving. When fastening into dissimilar metals, consider using anti-seize compound to prevent galling of the stainless threads. Verify thread engagement depth meets the requirements of the application before torquing to final specification.
