Sized at 1\/2-20 UNF with a 1-3\/4-inch length under head, this screw is fully threaded and uses a 3\/8-inch hex drive socket. Constructed from alloy steel with a zinc-plated finish, it delivers corrosion resistance and the tensile strength needed for demanding bolted connections. It meets ASTM B695 standards for zinc coating. This fastener is installed by mechanical contractors, millwrights, pipefitters, and maintenance technicians working with structural or mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in machinery assembly, equipment maintenance, structural bracketing, and general mechanical fastening where a fine-thread, high-strength screw is required. The 1\/2-20 UNF thread pattern is a fine-thread designation, offering better resistance to vibration loosening compared to coarse-thread equivalents. The zinc-plated alloy steel construction makes it appropriate for both indoor and moderate-exposure environments. Sold as a single piece with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF fine-thread profile resists loosening under vibration\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the entire 1-3\/4-inch length under head\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch hex drive socket for reliable torque application\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish meets ASTM B695 coating standards\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging with a minimum order quantity of 10\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-20 UNF hex socket cap screw for use in any application requiring a fine-thread alloy steel fastener of this thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by qualified mechanical or maintenance technicians using a 3\/8-inch hex key or socket driver. Always de-energize and lock out equipment before replacing fasteners in mechanical assemblies. Apply appropriate thread-locking compound or torque to specification per the equipment manufacturer's guidelines. Do not mix thread standards — confirm mating threads are UNF before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1-3\/4 inches\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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM B695\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 piece\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 837399PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694334509362,"sku":"837399PR","price":1056.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_10cd1180-d78d-43d1-9804-80601dcaa7d1.jpg?v=1788323264","url":"https:\/\/voomisupply.com\/products\/value-collection-837399pr-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
