The VALUE COLLECTION R40660443 is a hex socket cap screw designed for precision fastening in threaded assemblies requiring a compact, recessed-drive profile. Built to 5-40 UNC thread specification with a 3/8 inch length under head and a 3/32 inch hex drive, this screw delivers reliable clamping force in tight spaces where a standard external-drive fastener will not fit. Manufactured from 18-8 stainless steel, it provides solid corrosion resistance for use in both indoor and exposed environments. Electricians, HVAC technicians, plumbers, and mechanical trades installers use socket cap screws like this when working with panel assemblies, equipment enclosures, and precision hardware mounting.
This screw is suited for light-duty to medium-duty threaded fastening applications across residential and commercial trade work. The 5-40 UNC thread size makes it a common choice for small equipment panels, instrument enclosures, and machine components where fine thread engagement and a low-profile head are needed. The 18-8 stainless steel construction makes it appropriate for applications where mild corrosive exposure is a concern, such as plumbing and HVAC equipment mounting. Sold individually, with a minimum order quantity of 100 units per order.
Designed as a standard 5-40 UNC hex socket cap screw for use in any threaded assembly or tapped hole conforming to the 5-40 UNC thread standard.
Installation requires a 3/32 inch hex key or Allen driver. Ensure the mating tapped hole conforms to 5-40 UNC thread form before installation. De-energize any electrical panel or equipment fully before accessing internal fasteners. Do not overtighten stainless steel fasteners into stainless tapped holes, as galling can occur; apply anti-seize compound when appropriate.
