It features an M6x1 thread size, a 40 mm overall length, and a fully threaded shank. The 90-degree flat head seats flush with the mating surface, eliminating protrusion in countersunk assemblies. Built from 12.9 grade alloy steel, this fastener delivers tensile strength suitable for precision mechanical, tooling, and industrial applications. The Metric Blue finish provides a corrosion-resistant coating with consistent visual identification. Drive engagement is through a 4.00 mm hex socket, compatible with standard metric Allen keys and socket drivers.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for applications requiring a flush, low-profile head profile in metal-to-metal assemblies. Typical installation scenarios include machine frames, jigs, fixtures, tooling plates, and mechanical subassemblies where high clamp load and a countersunk seating surface are required. The fully threaded configuration maximizes thread engagement across the full length, making it appropriate for short-grip or thin-stack assemblies. Minimum order quantity is 10 pieces per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM6x1 metric thread with fully threaded shank for maximum engagement\u003c\/li\u003e\n  \u003cli\u003e90-degree flat head seats flush in standard countersunk holes per DIN 7991\u003c\/li\u003e\n  \u003cli\u003e12.9 alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003e4.00 mm hex socket drive for use with standard metric Allen keys\u003c\/li\u003e\n  \u003cli\u003eMetric Blue finish for corrosion resistance and visual grade identification\u003c\/li\u003e\n  \u003cli\u003e40 mm overall length measurement for consistent fitment specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 7991 standard metric flat socket cap screw.

Verify that the mating countersink is machined to the correct 90-degree included angle before seating the fastener. Torque to fastener manufacturer specifications for the appropriate clamp load at grade 12.9. Never reuse fasteners that have been overtorqued or show signs of galling on the thread flanks.\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\u003eLength\u003c\/strong\u003e: 40.00 mm (overall length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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: 4.00 mm\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: Metric Blue\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: DIN 7991\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: METRIC BLUE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UST184045\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"METRIC BLUE","offers":[{"title":"Default Title","offer_id":67910873710898,"sku":"UST184045","price":1422.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee2ad8fc51001baf98daab969736b17a_858cfdee-c690-433c-a080-c5ab938c228b.jpg?v=1791201007","url":"https:\/\/voomisupply.com\/products\/metric-blue-ust184045-flat-socket-cap-screw-m6x1-40mm","provider":"Voomi Supply","version":"1.0","type":"link"}
