It measures 2-1\/2 inches under the head and is manufactured from 18-8 stainless steel, which provides strong corrosion resistance in wet, chemical-exposed, or outdoor environments. The 1-5\/16-inch hex drive accepts standard hex wrenches and impact sockets. Thread standard is UNC (Unified National Coarse), the most common inch-series thread form. This fastener is used by millwrights, pipefitters, maintenance mechanics, and general contractors where stainless steel is specified over plated carbon steel.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for structural and mechanical assemblies across commercial, industrial, and marine environments. The 18-8 grade stainless designation indicates an austenitic alloy with approximately 18 percent chromium and 8 percent nickel, making it appropriate for applications where rust resistance and moderate strength are both required. Typical uses include equipment framing, pump and motor mounting, pipe supports, and enclosure hardware where hardware is exposed to moisture or mild corrosives.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction resists corrosion in wet and chemically active environments\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread for broad compatibility with standard inch-series tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e2-1\/2 inch length under head for use in moderate-depth through-bolt and tapped applications\u003c\/li\u003e\n  \u003cli\u003e1-5\/16 inch hex drive accepts standard open-end, box, and impact wrenches\u003c\/li\u003e\n  \u003cli\u003eNon-magnetic austenitic stainless alloy suitable for food-service and marine contexts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw compatible with any 7\/8-9 UNC tapped hole or matching hex nut in structural and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 1-5\/16 inch open-end, combination, or socket wrench. Ensure mating threads are clean and free of debris before assembly. Stainless steel fasteners are susceptible to galling under high torque; applying an anti-seize compound appropriate for stainless is strongly recommended. Follow applicable fastener torque guidelines for the assembly and material being joined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 1-5\/16 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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 400584PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711749030194,"sku":"400584PS","price":17.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d7b01224ddfaca02d2abca67c66b4dd.jpg?v=1788479173","url":"https:\/\/voomisupply.com\/products\/value-collection-400584ps-hex-head-cap-screw-7-8-9-2-5in-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
