Value Collection BD-63519 1/4-20 Unc Hex Socket Cap Screw

Product Description

The VALUE COLLECTION BD-63519 is a 1/4-20 UNC hex socket cap screw machined from 316 stainless steel with a 1-inch length under head. The internal hex drive accepts a standard hex key for installation in tight clearance areas where a wrench or open-head driver cannot reach. The 316 stainless alloy provides strong resistance to corrosion and oxidation, making this fastener suitable for wet, chemical-exposure, and marine environments. Plumbers, pipefitters, HVAC technicians, and industrial maintenance crews commonly specify this grade and thread pattern for equipment panels, brackets, flanges, and component assemblies.

This fastener is used across residential and commercial applications wherever a low-profile, high-strength cap screw is required. Typical install scenarios include equipment enclosure assembly, pump and valve mounting, HVAC component brackets, and general mechanical assembly work. The 1/4-20 UNC thread is one of the most common coarse-thread sizes in North American trade work, and the 316 stainless construction makes it a preferred choice over carbon steel in corrosive or high-moisture environments.

Key Features

• 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• 1/4-20 UNC coarse thread for broad compatibility with standard North American hardware
• 1-inch length under head suits moderate-depth fastening applications
• Internal hex socket drive allows installation in confined spaces with a hex key or Allen driver
• Low-profile cap head reduces protrusion in assembled equipment

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any application requiring a 1/4-20 coarse-thread fastener with an internal hex drive and 316 stainless steel construction.

Installation Notes

Installation is typically performed by a mechanic, pipefitter, HVAC technician, or maintenance tradesperson using a hex key or socket driver sized to the internal drive. Always de-energize equipment and relieve system pressure before disassembling or reassembling fastened components. Torque to the assembly specification provided by the equipment manufacturer. In stainless-to-stainless thread engagement, apply an anti-seize compound to prevent galling.
