The VALUE COLLECTION R63064322 is a flat socket cap screw designed for applications where a flush or countersunk fastener is required. Sized at 5/16-18 UNC thread by 2 inches overall length, this screw features an 82-degree flat head profile and a 3/8-inch hex socket drive. It is manufactured from 18-8 stainless steel, providing solid corrosion resistance in wet, outdoor, and mildly chemical-exposed environments. Tradespeople and maintenance technicians reach for this fastener when a low-profile, high-strength connection is needed in equipment panels, enclosures, brackets, and mechanical assemblies.
This screw is suited for use across a wide range of trade and industrial applications, including HVAC equipment mounting, electrical enclosure assembly, plumbing fixture installation, and general mechanical maintenance. The UNC thread form is the standard for inch-fastener work throughout North American trade applications. The flat head seats flush with or below the mating surface when installed in a properly sized countersunk hole, eliminating protrusion that could interfere with covers, panels, or moving components.
Designed as an inch-series UNC flat socket cap screw for general mechanical, HVAC, electrical, and plumbing fastening applications where a 5/16-18 countersunk socket fastener is specified.
Install using a 3/8-inch hex key or Allen-type socket driver. The mating material must be pre-drilled with an appropriately sized countersink to achieve a proper flush seating of the 82-degree flat head. Avoid over-torquing stainless steel fasteners, as galling can occur — apply an anti-seize compound when fastening stainless into stainless threads. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
