Value Collection R63003061 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R63003061 is a hex socket cap screw designed for secure, flush or recessed fastening in mechanical, plumbing, and industrial applications. It features a 1/4-20 UNC thread size with a 1-1/2 inch length under head and a 3/16 inch hex drive. Constructed from 316 stainless steel, this fastener offers strong resistance to corrosion and chemical exposure, making it well suited for wet, marine, or chemically aggressive environments. Installers drive it using a standard hex key or Allen wrench. The 316 grade alloy provides higher corrosion resistance than 304 stainless, particularly in chloride-heavy settings.

This cap screw is appropriate for light to medium-duty mechanical assemblies, equipment mounting, pipe supports, and panel fastening across residential, commercial, and industrial settings. Typical applications include HVAC equipment frames, pool and water treatment equipment enclosures, and plumbing fixture assemblies where stainless fasteners are specified to prevent rust staining or galvanic corrosion. Maintenance technicians, pipefitters, and millwrights commonly use this fastener when corrosion resistance is a priority over cost.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 1-1/2 inch length under head for moderate-depth fastening applications
• 3/16 inch hex drive accepts standard Allen keys and hex bits
• 316 stainless steel construction provides superior corrosion and chloride resistance
• Socket cap head allows installation in recessed or tight-clearance locations

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for any application calling for a 316 stainless steel fastener with a 1-1/2 inch length under head and a 3/16 inch hex drive.

Installation Notes

Install using a 3/16 inch hex key or appropriately sized hex bit driver. Ensure the mating tapped hole is clean and free of debris before driving. De-energize or depressurize any equipment before fastening or removing fasteners in live mechanical or electrical assemblies. Avoid mixing stainless fasteners with dissimilar metals in direct contact in submerged or high-humidity environments to minimize galvanic effects.
