It measures 3 inches in length under the head with a 1-8 thread size in the Unified National Coarse (UNC) thread standard. Manufactured from Grade 5 steel with a zinc-plated finish, it offers solid tensile strength and basic corrosion resistance suitable for indoor and light outdoor use. This fastener meets ASME B18.2.1 and SAE J429 standards. It is a stock item for maintenance shops, contractors, and field service technicians who need reliable imperial-thread fasteners on hand.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in equipment assembly, structural connections, and general mechanical fastening where a UNC coarse-thread, partially threaded hex bolt is specified. The zinc-plated finish makes it appropriate for applications where moderate corrosion protection is required but not a high-performance coating. It is commonly installed in fabrication shops, mechanical rooms, and field maintenance environments by millwrights, pipefitters, general contractors, and maintenance technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 and ASME B18.2.1 standards\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread size ensures wide tooling and nut compatibility\u003c\/li\u003e\n  \u003cli\u003ePartial threading allows for grip-length clamping in bolted joints\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or stock fastener for any application requiring a 1-8 UNC hex head cap screw in Grade 5 steel with a zinc-plated finish per ASME B18.2.1 and SAE J429 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard hex wrench or socket set sized to the appropriate hex head dimension for this 1-8 fastener.
