Manufactured from alloy steel to Grade 14.9 (45H), it delivers high tensile and torsional strength suited to demanding fastening applications. The M3 x 0.50 thread pitch and 4 mm overall length make it a compact but capable fastener for tight assemblies. Drive is via a 1.50 mm hex key socket. This screw meets DIN 916, the internationally recognized standard for cup point socket set screws. Machinists, millwrights, and assembly technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis set screw is appropriate for light mechanical assemblies where a cup point is needed to bite into a shaft or soft substrate and resist rotational movement. Typical uses include knobs, pulleys, gears, and encoder wheels in industrial, HVAC, and precision equipment applications. The metric M3 thread class is common in imported equipment and OEM assemblies where inch-series fasteners are not specified. Sold individually per package with a minimum order quantity of 100 pieces, making it practical for production runs and service stock replenishment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCup point geometry bites into shaft surfaces to resist rotation and axial movement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction at Grade 14.9 (45H) for high clamping force in small diameters\u003c\/li\u003e\n  \u003cli\u003eHex socket drive accepts a 1.50 mm hex key for installation in recessed or tight clearance locations\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 916 fastener standard for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eMetric M3 x 0.50 thread compatible with standard metric tapped holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any M3 x 0.50 tapped hole requiring a headless cup point set screw per DIN 916.

Ensure the mating tapped hole is clean and free of debris before threading. Do not exceed the rated torque for M3 alloy set screws as specified by the equipment manufacturer. Grade 14.9 alloy steel may be susceptible to hydrogen embrittlement if exposed to certain plating processes or aggressive chemical environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3 x 0.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 mm\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: 1.50 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: 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\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161505\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: 533002PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702492430642,"sku":"533002PR","price":1164.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8a9382a314d823c44dfd2f5af7171ad.jpg?v=1788411454","url":"https:\/\/voomisupply.com\/products\/value-collection-533002pr-m3-x-0-50-x-4-mm-cup-point-set-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
