Sized at 1\/2-13 UNC thread with a 2-inch length under head, this fastener is driven with a 3\/8-inch hex key. It is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection on the fastener head. This screw meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for structural and mechanical assemblies across industrial, construction, and maintenance applications.\u003c\/p\u003e\u003cp\u003eThis cap screw is used in general mechanical and structural fastening where a flush or recessed socket drive is preferred over an external hex head. The fully threaded 1\/2-13 UNC configuration suits through-bolt and blind-hole installations in steel frames, machinery bases, brackets, and equipment enclosures. It is commonly installed by millwrights, maintenance technicians, pipefitters, and general contractors working in light to heavy industrial environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread size for broad compatibility with standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003e2-inch length under head provides adequate grip range for typical structural connections\u003c\/li\u003e\n\u003cli\u003eFully threaded shank maximizes thread engagement in shallow or through-hole applications\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive allows installation with standard Allen keys or hex-bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 for high tensile strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish offers mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series socket cap screw for use in any application requiring a 1\/2-13 UNC threaded fastener with a hex socket drive and 2-inch length under head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/8-inch hex key or Allen-style bit driver. Ensure the mating tapped hole or nut is clean and free of debris before driving. Apply appropriate thread lubricant or anti-seize compound when required by the application or governing specification.
