It features an M12 x 1.75 thread profile with a 60 mm length under head and partial threading along the shank. Manufactured from alloy steel with a black oxide coating, this fastener meets material grade 12.9 — the highest standard strength class for metric hex socket cap screws — making it suitable for demanding clamping and structural bolting work. The internal hex drive accepts a standard hex key for installation in confined or recessed spaces where a wrench cannot access the fastener head.\u003c\/p\u003e\u003cp\u003eThis screw is used across a broad range of mechanical and industrial applications where high tensile strength and precise torque retention are required. Typical install scenarios include machine frames, hydraulic component mounting, gearbox covers, and equipment assemblies. The black oxide finish provides mild corrosion resistance and reduces surface reflectivity. Installation is performed by mechanical contractors, millwrights, and maintenance technicians. Partial threading along the shank provides shear-load capacity and alignment precision in through-bolted joints.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM12 x 1.75 thread size with 60 mm length under head\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for improved shear resistance in structural joints\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction at material grade 12.9 for maximum tensile strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating for mild corrosion resistance and low-reflectance finish\u003c\/li\u003e\n\u003cli\u003eInternal hex drive for installation in tight or recessed locations\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 an OEM-style and aftermarket replacement hex socket cap screw for applications requiring M12 x 1.75 metric thread fasteners per DIN 912 and ISO 4762 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified mechanical technicians or millwrights using a calibrated torque wrench and the appropriate metric hex key. De-energize and lock out all equipment before servicing any fastened assembly. Grade 12.9 fasteners should not be substituted with lower-grade hardware in structural or high-load joints. Follow applicable ASME or equipment manufacturer torque guidelines for M12 fasteners in the specific joint material.\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: 60 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 Standard\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: 0.154 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: 76388\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51731772211506,"sku":"76388","price":1488.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/430f2e208fe22c07f98debbe43d90840.jpg?v=1788734775","url":"https:\/\/voomisupply.com\/products\/holo-krome-76388-hex-socket-cap-screw-m12-x-1-75-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
