It features an M16 x 2.00 thread profile with a 130 mm length under head and is partially threaded along the shank. Manufactured from alloy steel at material grade 12.9, it carries a black oxide finish coating that provides moderate corrosion resistance and reduces light reflection on exposed fastener heads. The internal hex drive accepts a standard hex key for installation and removal. This fastener is installed by millwrights, maintenance mechanics, pipefitters, and mechanical contractors.\u003c\/p\u003e\u003cp\u003eThis screw is suited for bolted assemblies requiring high clamp load, including machinery frames, hydraulic component mounting, structural brackets, and heavy equipment fabrication. The grade 12.9 alloy steel construction delivers tensile strength appropriate for demanding mechanical joints where standard hardware-grade fasteners are insufficient. The black oxide finish is commonly specified in applications where a low-profile, non-reflective fastener appearance is required alongside moderate surface protection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM16 x 2.00 metric thread, partially threaded shank\u003c\/li\u003e\n\u003cli\u003e130 mm length under head for deep-reach bolted joints\u003c\/li\u003e\n\u003cli\u003eGrade 12.9 alloy steel construction for high tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish coating for moderate corrosion resistance and reduced glare\u003c\/li\u003e\n\u003cli\u003eInternal hex socket drive for precise torque application with hex keys\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard metric hex socket cap screw conforming to DIN 912 and ISO 4762, making it interchangeable with any application specifying an M16 x 2.00 partially threaded socket head cap screw at grade 12.9.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a correctly sized metric hex key or socket hex bit rated for high-torque applications. Always verify mating thread condition and thread engagement depth before final assembly. Apply appropriate thread lubricant or thread-locking compound per the assembly specification. Inspect the fastener seating surface to ensure full, even contact under the cap head before torquing to the value specified in the equipment or assembly documentation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M16 x 2.00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 130 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 12.9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standards\u003c\/strong\u003e: ANSI B1.13M, DIN 912, ISO 4762, ISO 898-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.56 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: HOLO-KROME\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 76478\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51736742166834,"sku":"76478","price":18.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cecd16f6270a853ef1fffbbdf0eeeefd.jpg?v=1788779724","url":"https:\/\/voomisupply.com\/products\/holo-krome-76478-hex-socket-cap-screw-m16x2-130mm-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
