It conforms to DIN 916, the metric standard for hexagon socket set screws with cup points. The cup point geometry bites into the mating shaft surface to resist rotational and axial movement without requiring a through-hole or protruding head. This fastener is driven with a 4.00 mm hex key. Each package contains 50 pieces, making it suitable for production assembly, maintenance stock, or bench inventory. Mechanical contractors, millwrights, and equipment technicians commonly use this type of fastener in motor couplings, shaft collars, pulleys, and similar rotating components.\u003c\/p\u003e\n\u003cp\u003eThis set screw is appropriate for metric threaded bores requiring an M8 x 1.25 thread pitch. At 10 mm overall length, it fits shallow engagement depths common in shaft collar and hub applications across light industrial, HVAC equipment, and mechanical systems. Grade 14.9 (45H) alloy steel construction provides high tensile and proof load capacity, making it well suited for high-torque or vibration-prone installations where fastener retention is critical. The 50-piece pack supports both single-use repair work and ongoing service inventory needs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point tip bites into shaft surface for positive grip without a protruding head\u003c\/li\u003e\n  \u003cli\u003eGrade 14.9 (45H) alloy steel construction delivers high proof load and tensile strength\u003c\/li\u003e\n  \u003cli\u003eDIN 916 standard ensures dimensional consistency and interchangeability\u003c\/li\u003e\n  \u003cli\u003eM8 x 1.25 metric thread with 10 mm overall length for shallow-bore applications\u003c\/li\u003e\n  \u003cli\u003e4.00 mm hex key drive for precise torque application in tight clearances\u003c\/li\u003e\n  \u003cli\u003e50-piece packaging supports production assembly and stocked maintenance inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 916 metric hex socket cup point set screw for use in any M8 x 1.25 threaded bore requiring a 10 mm overall length fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright using a calibrated 4.00 mm hex key or hex bit driver. Ensure the mating shaft and threaded bore are clean and free of debris before driving the screw. Do not exceed the torque rating of the Grade 14.9 (45H) fastener or apply thread-locking compounds unless specified by the equipment manufacturer. Follow applicable machinery safety procedures and lock out or tag out equipment before servicing any rotating assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8 x 1.25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 10 mm overall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cup\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key 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: Grade 14.9 (45H)\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 916\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 42939\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697524867378,"sku":"42939","price":18.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1faf4e3c4e346981c19ad300b8380ed.jpg?v=1788352484","url":"https:\/\/voomisupply.com\/products\/value-collection-42939-set-screw-m8-x-1-25-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
