It features an M20 x 2.5 thread and a 100 mm length under head, with a hex socket drive that accepts a standard hex key or Allen driver. Manufactured from alloy steel to a 12.9 material grade, this fastener delivers exceptional tensile and shear strength. The Metric Blue finish provides a baseline level of corrosion resistance while meeting DIN 912 and ISO 4762 dimensional standards. Machinists, millwrights, and mechanical assemblers commonly specify this fastener where high clamp loads and precise torque values are required.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is suited for medium-to-heavy machine assemblies, fixture construction, equipment mounting, and structural connections where a recessed drive head is preferred for clearance or aesthetics. The partial threading allows the unthreaded shank to act as a locating or shear pin in close-tolerance bored holes. It is appropriate for use in manufacturing plants, maintenance shops, and OEM production environments. The 12.9 grade alloy steel construction makes it well-suited for applications that demand higher proof load capacity than standard Grade 8 or 10.9 fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM20 x 2.5 thread with 100 mm length under head\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports close-tolerance and shear-load applications\u003c\/li\u003e\n  \u003cli\u003e12.9 alloy steel construction for high tensile and proof load capacity\u003c\/li\u003e\n  \u003cli\u003eHex socket drive for recessed installation with standard hex keys or Allen drivers\u003c\/li\u003e\n  \u003cli\u003eMetric Blue finish meets DIN 912 and ISO 4762 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eUNSPSC Code 31161501 for procurement system compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit fastener for assemblies specifying DIN 912 or ISO 4762 socket cap screws in M20 x 2.5 thread size with 100 mm length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or mechanical assembler using a properly sized hex key or Allen driver. Always de-energize and lock out equipment before replacing structural fasteners in powered machinery. Apply thread lubricant or anti-seize compound according to the assembly specification when required to achieve accurate clamp load from applied torque. Inspect the threaded bore for damage or contamination before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M20 x 2.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 100 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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\u003c\/strong\u003e: Metric Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: DIN 912, ISO 4762\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0066 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: UST176318\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"METRIC BLUE","offers":[{"title":"Default Title","offer_id":67914159948082,"sku":"UST176318","price":20.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71f5e2e6c143b56433eac2df9951bdaf_10643828-1040-4b93-b201-28063002e503.jpg?v=1791247580","url":"https:\/\/voomisupply.com\/products\/metric-blue-ust176318-socket-cap-screw-m20x2-5-100mm","provider":"Voomi Supply","version":"1.0","type":"link"}
