It features a 12-28 UNF thread size with a 1-inch length under head and is fully threaded along its entire shank. The screw is driven with a 5\/32-inch hex key. Manufactured from alloy steel with a black oxide coating, it delivers corrosion resistance and surface hardness suited to demanding service environments. This fastener conforms to ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for precision and structural fastening work.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in general industrial, mechanical, and trade-service applications where a low-profile, high-strength socket head cap screw is required. Typical installations include machinery, fixtures, enclosures, brackets, and equipment frames. The fine 28-thread-per-inch pitch provides greater thread engagement and resistance to loosening under vibration compared to coarse-thread equivalents. It is appropriate for use by machinists, millwrights, HVAC technicians, electricians, and general maintenance professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12-28 UNF fine thread for improved vibration resistance and precise torque control\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement along the full 1-inch length under head\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex drive compatible with standard Allen keys and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\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 application requiring a 12-28 UNF fully threaded fastener with a 1-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 5\/32-inch hex key or socket bit driver. Ensure mating threads are clean and free of debris before installation. Apply thread-locking compound if vibration resistance beyond the fine-thread engagement is required. Do not exceed the rated torque for the alloy steel grade when fastening into softer base materials such as aluminum or plastic.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 12-28 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 581354PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714365325618,"sku":"581354PR","price":1180.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f018f35b8c7b190ba17d6c26935f7cc6.jpg?v=1788500303","url":"https:\/\/voomisupply.com\/products\/value-collection-581354pr-hex-socket-cap-screw-12-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
