Featuring a 90-degree flat head and a 12 mm hex socket drive, it accepts a standard hex key for installation. The M20x2.5 thread and 90 mm overall length make it suited for medium-to-heavy duty structural and mechanical assemblies. Constructed from 18-8 austenitic stainless steel meeting Grade A2 designation, the screw offers corrosion resistance appropriate for both indoor and outdoor environments. The shank is partially threaded, which is typical for load-bearing bolted joints where thread engagement is limited to the nut or tapped section.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is used in general metalworking, fabrication, and mechanical assembly applications where a low-profile countersunk head is required. The DIN 7991 fastener standard ensures dimensional consistency for use in metric-designed assemblies. It is appropriate for machine frames, brackets, guards, and structural panels where flush mounting is necessary. Installers working in food service, marine, or chemical-adjacent environments may prefer the A2 stainless grade for its corrosion resistance compared to carbon steel alternatives.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree flat head profile allows flush or countersunk installation\u003c\/li\u003e\n  \u003cli\u003e12 mm hex socket drive for use with standard hex keys or socket drivers\u003c\/li\u003e\n  \u003cli\u003eM20x2.5 metric thread size with partial threading for shear-load joints\u003c\/li\u003e\n  \u003cli\u003e18-8 austenitic stainless steel, Grade A2, for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 7991 fastener standard for dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003e90 mm overall length suits medium-depth countersunk assemblies\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 in M20x2.5 thread size, compatible with any metric-tapped hole or nut meeting the same thread specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist, millwright, or general tradesperson using a 12 mm hex key or socket driver. Ensure the mating countersunk hole is machined to a 90-degree included angle to match the head geometry. Verify thread engagement depth and torque to the assembly specification; do not over-torque stainless steel fasteners as galling can occur. Applying an anti-seize compound to the threads is recommended when torque consistency is critical.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20x2.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 90 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: 12 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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8 Austenitic Grade A2\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: 0.0049 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 538306BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701704687922,"sku":"538306BR","price":65.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_828d3784-5263-4aea-874c-3cd9b6caf643.jpg?v=1788404083","url":"https:\/\/voomisupply.com\/products\/value-collection-538306br-m20x2-5-flat-socket-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
