Manufactured from alloy steel to material grade 12.9, it delivers exceptional tensile strength for demanding structural and mechanical assemblies. The black oxide coating provides a base level of corrosion resistance and reduces light reflection, making it suitable for both industrial and precision equipment environments. The screw measures M12 x 1.75 thread pitch with a 90 mm length under head and is partially threaded, allowing it to clamp mating components without threading engagement through the full grip length. It is driven with a hex socket tool.\u003c\/p\u003e\u003cp\u003eThis fastener is appropriate for use in machinery, tooling fixtures, equipment frames, and structural assemblies where high clamp loads and close tolerances are required. The 12.9 material grade rating makes it suitable for applications where standard-grade fasteners would be undersized for the load. It is commonly installed by machinists, millwrights, mechanical contractors, and maintenance technicians working on industrial and commercial equipment. Partial threading supports accurate bolt-hole alignment and bearing-surface clamping across a defined grip zone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM12 x 1.75 thread size with 90 mm length under head for deep-reach fastening\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction rated to material grade 12.9 for high tensile and proof load requirements\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank maintains full clamping force across the grip length\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish reduces surface corrosion and minimizes light reflection\u003c\/li\u003e\n\u003cli\u003eHex socket drive allows high-torque installation in confined or recessed spaces\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 fastener 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, suitable for use in any application or fixture that accepts an M12 x 1.75 partially threaded socket head cap screw to those dimensional standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical or maintenance personnel using a calibrated hex socket key or driver sized for M12 socket head cap screws. Ensure the mating threaded hole or nut meets the load requirements of a grade 12.9 fastener before assembly. Lubrication of the threads and bearing surface is recommended where specified by the equipment manufacturer to achieve accurate torque-to-clamp-load results. Do not mix grade 12.9 fasteners with lower-grade hardware in the same joint without an engineering review.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12 x 1.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 90 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\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: 0.22 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: 76408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51753445556530,"sku":"76408","price":11787.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c400790625e97ecd112fec1106946b81.jpg?v=1788936856","url":"https:\/\/voomisupply.com\/products\/holo-krome-76408-hex-socket-cap-screw-m12-x-1-75-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
