It features a 1\/2-20 UNF thread with a 1-inch length under head and is fully threaded along its entire shank. The 3\/8-inch hex drive accepts a standard hex key or socket drive tool. Constructed from alloy steel with a black oxide coating, this screw provides corrosion resistance and reduced light reflection in industrial environments. It meets ASME\/ANSI B18.3 and ASTM A574 dimensional and mechanical standards.\u003c\/p\u003e\u003cp\u003eThis screw is suited for precision mechanical work where fine-thread engagement is required, including machine frames, hydraulic components, and close-tolerance assemblies. The fine 1\/2-20 UNF thread pitch provides higher thread engagement per inch compared to coarse-thread equivalents, making it a common choice in vibration-prone applications. It is typically installed by machinists, millwrights, and maintenance technicians working on industrial or mechanical systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-20 UNF fine thread for increased engagement strength in tight-tolerance assemblies\u003c\/li\u003e\n\u003cli\u003eFully threaded shank along entire 1-inch length under head\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive for use with standard hex keys or socket tools\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced surface glare\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 socket cap screw standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw compatible with any tapped 1\/2-20 UNF hole requiring a 3\/8-inch hex drive fastener in industrial or mechanical applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/8-inch hex key or Allen-type socket driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread-locking compound or torque per the assembly specification when vibration is a concern. Verify hole thread class and engagement depth before final torque-down.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20 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: 3\/8 inch\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\u003eStandard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 011393PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703722377522,"sku":"011393PR","price":5007.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67d447fc4b456985e84b25a6dc6b58e7.jpg?v=1788418227","url":"https:\/\/voomisupply.com\/products\/value-collection-011393pr-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
