It is driven with a 3\/8 inch hex key and constructed from 18-8 stainless steel with a bright, uncoated finish. This fastener is used wherever a high-strength, corrosion-resistant socket cap screw is required in mechanical assemblies, equipment frames, and industrial fixtures. Installers in plumbing, HVAC, electrical, and general mechanical trades rely on this type of fastener for secure, flush-profile clamping in tight clearance applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for fine-thread applications requiring controlled clamping force and resistance to vibration loosening. The 1\/2-20 UNF thread pitch provides greater thread engagement per inch compared to coarse-thread equivalents, making it a common choice in precision assemblies, pump housings, manifold flanges, and equipment panels where thread stripping resistance matters. The 18-8 stainless steel construction makes it appropriate for environments with moisture exposure or mild corrosive conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF fine thread for increased thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inch length under head for deep clamping reach in thick material stacks\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch hex socket drive for use with standard hex keys and socket drivers\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet or humid environments\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains dimensional tolerances without added coating buildup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock hex socket cap screw for mechanical assemblies requiring a 1\/2-20 UNF fine-thread fastener with a 3\/8 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/8 inch hex key or Allen-style socket driver. Always confirm thread engagement and seat the fastener into a properly tapped hole before applying final torque. Power down or de-energize any equipment before accessing fastener locations on electrical enclosures or mechanical assemblies. Follow applicable equipment manufacturer torque specifications and relevant mechanical or building codes for the application.\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: 3-1\/2 inches\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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: R57001083\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708072067378,"sku":"R57001083","price":1023.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_27cd9665-12d7-4758-8f6b-85eeeded9229.jpg?v=1788443880","url":"https:\/\/voomisupply.com\/products\/value-collection-r57001083-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
