The screw features a 4-40 UNC thread size with a 5\/16 inch length under head, driven by a 3\/32 inch hex key. The body is machined from 18-8 stainless steel, providing corrosion resistance in moderate-exposure environments. This type of fastener is commonly installed by machinists, millwrights, and assembly technicians in applications where a low-profile, high-strength cap screw with a recessed hex drive is required.\u003c\/p\u003e\u003cp\u003eThis screw is well suited for light-duty mechanical assemblies, instrument enclosures, electrical panel components, and small-gauge fabrication work where 4-40 UNC threading is specified. The 18-8 stainless steel construction makes it appropriate for environments with incidental moisture exposure. Its compact 5\/16 inch under-head length fits shallow clearance applications where longer fasteners would not seat properly. Sold individually, with a minimum order quantity of 100 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNC thread size for light-duty precision fastening\u003c\/li\u003e\n\u003cli\u003e3\/32 inch hex drive for use with standard Allen keys or hex drivers\u003c\/li\u003e\n\u003cli\u003e5\/16 inch length under head for shallow clearance installations\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eLow-profile socket cap head reduces protrusion in tight assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 UNC hex socket cap screw suitable for use in any application specifying 4-40 UNC threaded fasteners with a 5\/16 inch under-head length and 3\/32 inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/32 inch hex key or Allen driver.
