It features a 1-8 UNC thread size, a 4-inch length under the head, and a 3\/4-inch hex drive. The screw is partially threaded and manufactured from 18-8 austenitic stainless steel (Material Grade A2), providing reliable performance in wet, chemical-exposure, or outdoor environments. This fastener meets ASME\/ANSI B18.3 and ASTM F837 standards. It is used by millwrights, maintenance mechanics, pipefitters, and industrial technicians who require a socket-drive cap screw for structural and mechanical assembly work.\u003c\/p\u003e\u003cp\u003eThis screw is suited for general industrial, mechanical, and structural fastening applications. Its partial threading allows for clean clamping action in bolted joints where the unthreaded shank spans the grip length. The 1-8 UNC coarse thread provides strong engagement in tapped holes and is widely used in machine frames, equipment mounts, and flange connections. The bright, uncoated finish is appropriate for use with compatible stainless fastener hardware in corrosion-prone or cleanroom environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-8 UNC coarse thread for strong tapped-hole engagement\u003c\/li\u003e\n\u003cli\u003e4-inch length under head for use in thicker material stacks\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex socket drive for high-torque installation with standard hex keys or socket drivers\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides positive clamping in bolted joint applications\u003c\/li\u003e\n\u003cli\u003e18-8 austenitic stainless steel (Grade A2) for corrosion resistance\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 for use in any application requiring a 1-8 UNC hex socket cap screw with a 4-inch length under head and a 3\/4-inch drive.

Power down or de-energize any equipment before fastening near live electrical components. Apply appropriate anti-seize compound when joining dissimilar metals or in high-temperature environments to prevent galling on stainless threads. Follow applicable torque guidelines per your engineering specification or applicable mechanical code for the joint material and fastener grade.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 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\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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; ASTM F837\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 592503BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51724011110706,"sku":"592503BR","price":31.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c9a2a0009891924a2ca223b5da382b3_9e34a2b0-2a3b-48a3-91ee-d0efb90edc23.jpg?v=1788611520","url":"https:\/\/voomisupply.com\/products\/value-collection-592503br-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
