It features a 3\/8-16 UNC thread size, a 1-3\/8 inch length under head, and a 5\/16 inch hex drive. The fastener is machined from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection. This screw is fully threaded and conforms to ASME\/ANSI B18.3 and ASTM A574 standards. It is used by machinists, millwrights, pipefitters, and maintenance technicians working in equipment assembly and structural fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for residential and commercial equipment assembly, machine building, fixture fabrication, and structural component fastening. The 3\/8-16 UNC coarse thread provides reliable engagement in steel, cast iron, and other ferrous materials. The hex socket drive allows for high torque application in confined spaces where a wrench or open-drive tool cannot reach. It is commonly used in HVAC equipment frames, pump housings, electrical enclosures, and general mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 UNC fully threaded coarse thread for strong engagement in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e1-3\/8 inch length under head for medium-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch hex socket drive enables high-torque installation in tight spaces\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides moderate corrosion and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any threaded hole or nut accepting a 3\/8-16 UNC coarse thread pattern.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a 5\/16 inch hex key or socket driver. De-energize and lock out all equipment before fastening or removing hardware in mechanical assemblies. Do not over-drive; apply torque gradually and verify thread engagement before full tightening.
