Value Collection R63064482 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION R63064482 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a 3/8-inch hex socket drive and an 82-degree flat head that seats flush with or below the mating surface when properly countersunk. The fastener is manufactured from 18-8 stainless steel, providing solid corrosion resistance in wet, chemical-exposed, or outdoor environments. Thread size is 5/16-18 UNC with an overall length of 5/8 inches. This screw is installed using a hex key or Allen driver and is suited for machinists, maintenance technicians, and fabricators working in light-duty mechanical assemblies.

This flat socket cap screw is commonly used in machine frames, brackets, panels, and fixtures where a low-profile or flush fastener is required. The UNC thread form is standard for inch-system assemblies across industrial, HVAC equipment, and general fabrication applications. Its 18-8 stainless steel construction makes it appropriate for environments with moderate moisture or mild chemical exposure, including pool equipment enclosures, plumbing panels, and outdoor electrical fixtures. Sold individually with a minimum order quantity of 100 units.

Key Features

• 82-degree flat head seats flush with the mating surface for a low-profile installation
• 3/8-inch hex socket drive accepts standard Allen keys or hex bit drivers
• 18-8 stainless steel construction resists corrosion in wet and mildly corrosive environments
• 5/16-18 UNC thread standard for compatibility with inch-system tapped holes
• Overall length of 5/8 inches suits shallow countersunk applications

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any tapped hole or threaded insert with a 5/16-18 UNC thread form and a countersunk seating surface machined to an 82-degree included angle.

Installation Notes

Install using a calibrated 3/8-inch hex key or Allen-type bit driver. Ensure the mating countersink is machined to an 82-degree included angle before driving the screw flush. Power down or de-energize any equipment before accessing internal fasteners on electrical or HVAC assemblies. Avoid over-torquing stainless steel fasteners, as the material is susceptible to galling; apply an appropriate anti-seize compound when fastening into stainless or aluminum tapped holes.
