It features a 1\/2-20 UNF thread size and a 2-inch length under head, with full threading along the shank. The drive is a 3\/8-inch hex socket, requiring a standard Allen or hex key driver. Constructed from 18-8 austenitic stainless steel (Grade A2) with a bright, uncoated finish, this fastener resists corrosion in wet or chemically active environments. It meets ASME\/ANSI B18.3 and ASTM F837 standards, making it suitable for applications requiring traceable fastener specifications.\u003c\/p\u003e\u003cp\u003eThis screw is used in mechanical, industrial, and maintenance applications where a recessed-drive cap screw is preferred for clearance or torque control. Fully threaded construction allows engagement along the entire shank length, which is useful in thin-material or close-tolerance assemblies. Typical installers include millwrights, maintenance mechanics, and field technicians working on equipment frames, pump housings, bracket assemblies, and similar structural connections requiring corrosion-resistant hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread size 1\/2-20 UNF with full threading along shank\u003c\/li\u003e\n\u003cli\u003e2-inch length under head for through-bolt and tapped-hole applications\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive for standard Allen key or hex driver\u003c\/li\u003e\n\u003cli\u003e18-8 austenitic stainless steel, Grade A2 for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating thickness to account for in tight-tolerance fits\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F837 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or aftermarket hex socket cap screw for tapped holes or nuts with 1\/2-20 UNF internal threads in mechanical and industrial equipment assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/8-inch hex key or socket driver; apply fastener torque according to the equipment manufacturer's specifications for 1\/2-20 stainless steel hardware. Avoid over-torquing stainless steel fasteners, as galling can occur — application of anti-seize compound is a common field practice to prevent thread seizure. Verify tapped-hole thread class and depth before installation to ensure full engagement. Always de-energize or lock out equipment before accessing fastener locations on powered machinery.\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: 2 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: Stainless Steel, 18-8 Austenitic Grade A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM F837\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: 592409PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712226328882,"sku":"592409PR","price":2482.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_2d2eeb5d-53a2-4790-8995-deb11af20092.jpg?v=1788485417","url":"https:\/\/voomisupply.com\/products\/value-collection-592409pr-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
