Built to DIN 7991 standard, this screw features a 90-degree flat head with a hex socket drive and is manufactured from 12.9-grade alloy steel for high tensile strength. The black oxide finish provides moderate corrosion resistance and reduces light reflection. The M4x0.7 thread with a 40 mm overall length is partially threaded. This fastener is suited for precision assemblies in mechanical, industrial, and equipment manufacturing environments where a flush surface is critical.\u003c\/p\u003e\u003cp\u003eThis screw is used in metal-to-metal and metal-to-plastic assemblies where the fastener head must sit flush with or below the mating surface. Typical applications include machine frames, tooling fixtures, jigs, enclosures, and precision mechanical components. The 12.9 material grade makes it appropriate for high-stress joints that require maximum clamping force in a compact fastener profile. Installation is performed by machinists, millwrights, and mechanical assemblers using standard metric hex key tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDIN 7991 standard for consistent dimensional compliance\u003c\/li\u003e\n\u003cli\u003e12.9-grade alloy steel for high tensile and proof load capacity\u003c\/li\u003e\n\u003cli\u003e90-degree flat head profile allows flush or countersunk seating\u003c\/li\u003e\n\u003cli\u003eHex socket drive (2.50 mm) for precise torque application in tight spaces\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and low-reflectance appearance\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for controlled clamping in through-hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style metric fastener replacement or new installation screw for assemblies requiring DIN 7991-compliant M4 flat socket cap screws with a 90-degree countersink profile.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 2.50 mm hex key or ball-end driver rated for 12.9-grade fasteners. Ensure the mating countersink angle matches the 90-degree head geometry before installation to avoid galling or improper seating. Always confirm thread engagement depth meets engineering requirements before applying final torque. Follow applicable machinery and equipment manufacturer torque specifications for M4 class 12.9 fasteners.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4x0.7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 40 mm overall\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: 2.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\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: DIN 7991\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 534038PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691396563250,"sku":"534038PR","price":4586.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/089baa4a86b04b8a9bf8a765ad69bdd2.jpg?v=1788284461","url":"https:\/\/voomisupply.com\/products\/value-collection-534038pr-m4x0-7-flat-socket-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
