Grade 316 stainless steel provides superior corrosion resistance compared to 304 grade, making this fastener well-suited for wet, chemical, or marine environments. The coarse 7\/8-9 thread pitch and 5-1\/2 inch length under head are measured in the inch system. Partial threading leaves a smooth shank section for applications requiring a grip-length fit or shear-load bearing. This screw is installed by machinists, millwrights, pipefitters, and maintenance technicians across industrial and commercial settings.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is commonly used in structural assemblies, equipment mounting, pipe flanges, pump housings, and other applications where corrosion resistance and mechanical strength are required. The hex head design accepts standard hex wrenches and sockets for high-torque installation. Partial threading is appropriate where the joint requires a defined bearing shank rather than full thread engagement through the entire fastener length. Typical applications include marine hardware, chemical processing equipment, food-grade machinery, and outdoor structural assemblies exposed to moisture or corrosive agents.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 316 stainless steel construction for enhanced resistance to chloride and chemical corrosion\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for grip-length fit and shear load distribution\u003c\/li\u003e\n  \u003cli\u003eCoarse 7\/8-9 thread pitch for reliable engagement in standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains dimensional tolerances and avoids coating-related contamination\u003c\/li\u003e\n  \u003cli\u003eHex head drive accepts standard 6-point sockets and wrenches for high-torque installation\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for compatibility with standard US fastener tooling and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-inch partially threaded hex head cap screw for use with any 7\/8-9 tapped hole, nut, or coupling rated for Grade 316 stainless steel fasteners in industrial, marine, or commercial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists, millwrights, or maintenance technicians using the appropriate hex socket or wrench sized for a 7\/8-9 hex head fastener. De-energize, depressurize, or otherwise isolate any equipment before fastener replacement or assembly work. Apply anti-seize compound rated for stainless steel if the joint may be exposed to high heat or prolonged moisture to prevent galling during future removal. Follow applicable mechanical codes and equipment manufacturer guidelines for proper torque procedures.\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 (Inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5-1\/2 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: 316\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish \/ Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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: 1.11 pounds\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: 2-H-87C-550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717685575986,"sku":"2-H-87C-550","price":3456.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59466af6051d109dff68a5f912256f0d_0ea2a3a3-1675-463a-b1eb-53720f553ed3.jpg?v=1788544406","url":"https:\/\/voomisupply.com\/products\/value-collection-2-h-87c-550-hex-head-cap-screw-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
