Value Collection -63861-1 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION -63861-1 is a flat socket cap screw designed for fastening applications that require a flush or countersunk head profile. Sized at 1/4-20 UNC thread with an overall length of 1-3/4 inches, this screw is manufactured from 18-8 stainless steel for corrosion resistance in moderate-exposure environments. The 82-degree flat head seats flush with the work surface when installed in a properly countersunk hole. The hex socket drive accepts a 5/32-inch hex key for installation with a controlled torque. Maintenance technicians, fabricators, and trade professionals working in HVAC, plumbing, or electrical enclosure assemblies will encounter this fastener type in standard inch-system hardware applications.

This screw is suited for use in sheet metal assemblies, equipment panels, junction boxes, brackets, and structural components where a low-profile flush head is required. The 1/4-20 UNC thread is a common inch-series coarse thread found across a wide range of residential and commercial trade equipment. The 18-8 stainless steel construction makes it appropriate for installations exposed to moisture, mild chemicals, or outdoor conditions where carbon steel fasteners may corrode prematurely. This screw is sold in minimum order quantities of 50 units.

Key Features

• 82-degree flat head seats flush in a countersunk hole for a low-profile installation
• 18-8 stainless steel construction provides corrosion resistance in moisture-exposed environments
• 1/4-20 UNC coarse thread is a widely used inch-series standard for trade equipment and assemblies
• 5/32-inch hex socket drive for secure, cam-out-resistant installation with a standard hex key
• Overall length of 1-3/4 inches accommodates typical panel and bracket fastening depths

Compatibility

Designed as a standard inch-series flat socket cap screw compatible with any application requiring a 1/4-20 UNC thread, 1-3/4-inch overall length, and an 82-degree countersunk flat head seating surface.

Installation Notes

Installation requires a properly countersunk hole sized for an 82-degree flat head to achieve a flush seating surface. Use a calibrated 5/32-inch hex key or hex driver bit to drive the screw and avoid rounding the socket. De-energize and lock out any equipment before replacing fasteners on live assemblies in accordance with applicable OSHA lockout/tagout procedures. Do not mix stainless steel fasteners with dissimilar metals in environments prone to galvanic corrosion without appropriate isolation measures.
