Built from 12.9 grade alloy steel with a black oxide finish, this screw delivers exceptional shear and clamp load resistance in demanding assemblies. The 90-degree flat head seats flush into countersunk holes, eliminating protrusion that could interfere with mating surfaces or moving components. Drive engagement is through a 4 mm hex socket. Overall length is 40 mm with an M6x1 thread and a partially threaded shank, conforming to ANSI B1.13M and ISO 10642 standards. Licensed mechanics, machinists, and MRO professionals install this type of fastener in precision mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in metric machine assemblies, fixtures, tooling plates, and structural joints where countersunk seating is required. The 12.9 material grade makes it appropriate for high-stress environments including hydraulic component mounting, industrial machinery, and equipment requiring tight thread fit. The Thread Fit Class 4G designation supports controlled engagement in precision-tapped metric holes. Partial threading allows for tighter shoulder clamping in thick-material joints. Minimum order quantity is 100 pieces; individual package quantity is 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12.9 alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003e90-degree flat head profile seats flush in countersunk holes to eliminate surface protrusion\u003c\/li\u003e\n  \u003cli\u003e4 mm hex socket drive for standard hex key installation\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for improved clamping force in thick-material joints\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI B1.13M and ISO 10642 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in metric-threaded assemblies requiring an M6x1 countersunk socket cap screw with a 4G thread fit class per ANSI B1.13M and ISO 10642.

Ensure the mating hole is countersunk to 90 degrees and the thread is clean and free of debris before driving the fastener. Do not exceed the rated clamp load for the material grade; do not substitute lower-grade fasteners in high-load applications. Follow applicable machinery safety lockout procedures before disassembling or reassembling fastened joints.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M6x1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 90-degree Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 13.44 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3.72 inches decimal equivalent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 4G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Partially Threaded\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\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI B1.13M, ISO 10642\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 87112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51742634508594,"sku":"87112","price":9697.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8b6cf5eabe4350780b8d01963314cf8.jpg?v=1788838488","url":"https:\/\/voomisupply.com\/products\/holo-krome-87112-flat-socket-cap-screw-m6x1-12-9-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
