This screw features an M18 x 2.50 thread profile with a 55 mm length under head, manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection on the fastener surface. It conforms to DIN 912 and ISO 898-1 standards at material grade 12.9, the highest common strength grade for metric socket cap screws, making it suitable for applications where joint integrity and clamping force are critical.\u003c\/p\u003e\u003cp\u003eThis fastener is used in heavy equipment, machine frames, hydraulic cylinder mounting, tooling fixtures, and structural bolted connections where a recessed hex drive is preferred over external hex or torx profiles. The M18 diameter and 2.50 mm pitch are standard coarse-thread dimensions widely used in European and metric-specification equipment. Machinists, millwrights, and mechanical assembly technicians are the primary installers. Full threading along the shank allows engagement across varying joint depths without an unthreaded grip zone, which is useful in through-bolted and tapped-hole configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM18 x 2.50 coarse thread, fully threaded shank for maximum engagement flexibility\u003c\/li\u003e\n\u003cli\u003eGrade 12.9 alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and a consistent dark appearance\u003c\/li\u003e\n\u003cli\u003eHex socket drive reduces tool clearance requirements in tight installations\u003c\/li\u003e\n\u003cli\u003eMeets DIN 912 and ISO 898-1 fastener standards for dimensional and mechanical compliance\u003c\/li\u003e\n\u003cli\u003e55 mm length under head suits a range of joint stack thicknesses\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and general-purpose replacement or supplemental fastener for any M18 x 2.50 tapped hole or through-hole application requiring a DIN 912 hex socket cap screw at grade 12.9.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified millwright, machinist, or mechanical technician using a calibrated torque wrench and the appropriate metric hex key or socket bit sized for M18 socket cap screws. Always confirm the tapped hole thread class and depth are compatible with M18 x 2.50 before installation. De-energize, de-pressurize, and lock out all affected equipment before removing or installing structural fasteners. Do not substitute a lower grade fastener in a joint originally engineered for grade 12.9 without engineering review.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M18 x 2.50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 55 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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: DIN 912, ISO 898-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.38 pounds (package)\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: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 532531BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690828726578,"sku":"532531BR","price":64.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_8994134b-3b6d-4b82-845e-ba40ec700e77.jpg?v=1788275843","url":"https:\/\/voomisupply.com\/products\/value-collection-532531br-m18x2-5-hex-socket-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
