Value Collection R63061449 Flat Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R63061449 is a flat socket cap screw designed for fastening applications that require a flush or countersunk head profile. The 82-degree flat head seats fully into a countersunk hole, keeping the fastener surface-flush with the workpiece. Constructed from 18-8 stainless steel, it resists corrosion and is well suited for environments exposed to moisture, chemicals, or outdoor conditions. The hex socket drive accepts a 3/8-inch hex key for installation and removal. This fastener is installed by maintenance technicians, millwrights, machinists, and general tradespeople across mechanical, industrial, and structural applications.

This screw is used wherever a flush-mount fastening solution is required and corrosion resistance is a priority. Common applications include equipment panels, brackets, enclosures, pump housings, and structural assemblies in commercial and industrial settings. The UNC thread standard ensures compatibility with standard inch-series tapped holes. The 5/8-11 thread size and 2-inch overall length make it appropriate for medium-to-heavy fastening tasks where a standard hex or pan head fastener would protrude unacceptably.

Key Features

• 82-degree flat head profile for flush countersunk installations
• 18-8 stainless steel construction for corrosion resistance in wet or chemical-exposed environments
• 3/8-inch hex socket drive for positive tool engagement
• 5/8-11 UNC thread for compatibility with standard inch-series tapped holes
• 2-inch overall length suits medium-to-heavy depth fastening requirements

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application requiring a 5/8-11 UNC tapped hole and a countersunk 82-degree seat.

Installation Notes

Install using a 3/8-inch hex key or Allen-head driver bit. Ensure the receiving hole is properly countersunk to 82 degrees before installing to achieve full head seating. De-energize or lock out any equipment before fastening or removing screws in powered assemblies. Apply appropriate thread lubricant or anti-seize compound if the screw will be subject to repeated removal or high-temperature service.
