Value Collection 721220PR Flat Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 721220PR is a flat socket cap screw designed for applications requiring a flush or countersunk fastening profile. The 82-degree flat head seats flush with or below the surface of the mating material, eliminating protrusions that could interfere with mating components. Driven by a 3/32-inch hex socket, this screw measures 2.5 inches in overall length and is partially threaded with a number 8-32 UNC thread form. Constructed from alloy steel with a black oxide finish, it delivers solid mechanical strength and moderate corrosion resistance in interior or low-humidity environments. Licensed trades and industrial assembly technicians use this fastener in precision fixtures, machine components, and structural assemblies.

This flat socket cap screw suits inch-measurement applications in residential and light commercial mechanical assemblies where a low-profile, flush-mounted fastener is required. The 8-32 UNC thread size is common in electrical enclosures, instrument panels, and light mechanical structures. The partial threading allows for clearance-hole clamping force, pulling mating parts tightly together without threading into the clearance portion. Typical installers include machinists, electricians, HVAC technicians, and general mechanical contractors working with standardized inch-series hardware.

Key Features

• 82-degree flat head seats flush or countersunk for a clean, snag-free surface
• 3/32-inch hex socket drive for standard Allen-key or bit-driver installation
• Partially threaded shank provides clamping force in clearance-hole applications
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 fastener standards
• Black oxide finish reduces light reflection and provides moderate surface protection
• 8-32 UNC thread form is widely compatible with standard inch-series tapped holes

Compatibility

Designed as an OEM-style replacement or standard hardware component for applications using 8-32 UNC tapped holes requiring a countersunk flat-head socket cap screw per ASME/ANSI B18.3 and ASTM F835 specifications.

Installation Notes

Install using a calibrated 3/32-inch hex key or socket bit. Ensure the mating material is drilled and countersunk to the correct 82-degree included angle before installation. De-energize and lock out any equipment before servicing fasteners on electrical enclosures or powered assemblies. Do not exceed the rated drive torque for the 8-32 thread size, as overtightening alloy steel fasteners in soft mating materials can strip threads or damage the countersink.
