The 304 stainless steel construction provides corrosion resistance for outdoor, marine, and food-contact applications where carbon steel set screws would corrode. High-hardness treatment (HRC 45–50) ensures the cone tip maintains its geometry under load.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard:\u003c\/strong\u003e DIN914 \/ ISO 4027 (hex socket cone point set screw)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 304 stainless steel (A2), high-hardness treated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive:\u003c\/strong\u003e Internal hex (Allen key)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Style:\u003c\/strong\u003e Cone point — sharp conical tip for dimple engagement\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSizes:\u003c\/strong\u003e M3, M4, M5, M6, M8, M10 (multiple lengths per size)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread:\u003c\/strong\u003e Metric coarse pitch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Sizes:\u003c\/strong\u003e M3=1.5mm, M4=2mm, M5=2.5mm, M6=3mm, M8=4mm, M10=5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness:\u003c\/strong\u003e HRC 45–50 (high-hardness A2 stainless)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCone Point vs Cup Point vs Flat Point — When to Use Cone Point\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCone point (DIN914, this product):\u003c\/strong\u003e Highest holding force.

For applications subject to vibration, shock, or high torque, cone point is the correct choice.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"Can I use a cone point set screw without drilling a dimple?\"\u003c\/em\u003e — Technically yes, but the cone tip will simply mark the shaft surface without engaging a dimple, providing no more holding force than a cup point. The cone point’s advantage is only realized when used with a matching conical dimple.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"Is 304 stainless steel hard enough for set screws?\"\u003c\/em\u003e — Standard 304 stainless (A2-70) is too soft for set screws — the tip deforms under load. This product uses high-hardness treated 304 stainless (HRC 45–50), which provides adequate hardness for set screw applications while maintaining corrosion resistance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"What torque should I use for M6 cone point set screws?\"\u003c\/em\u003e — M6 DIN914 stainless: 6–8 Nm. Always use a calibrated torque wrench or torque-limiting hex key. Over-torquing shears the screw; under-torquing allows the cone tip to back out of the dimple under load.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision machinery:\u003c\/strong\u003e Permanent shaft-to-hub locking on gears, pulleys, and couplings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMarine \u0026amp; outdoor:\u003c\/strong\u003e Corrosion-resistant shaft locking on marine hardware, outdoor equipment, and food processing machinery\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRobotics:\u003c\/strong\u003e Servo output shaft locking, encoder disc positioning, actuator coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCNC \u0026amp; machining:\u003c\/strong\u003e Toolholder locking, fixture positioning, precision indexing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutomotive:\u003c\/strong\u003e Steering column components, throttle body shaft locking, sensor wheel positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003eAssortment kit — M3–M10 DIN914 cone point set screws in 304 stainless steel, multiple lengths per size, in labeled storage case.\u003c\/p\u003e","brand":"Cable Parts Online","offers":[{"title":"Point Tip-174pcs","offer_id":47850716430581,"sku":"14:29#Point Tip-174pcs","price":154.49,"currency_code":"USD","in_stock":true},{"title":"Point Tip-190pcs","offer_id":47850716463349,"sku":"14:175#Point Tip-190pcs","price":26.36,"currency_code":"USD","in_stock":true},{"title":"Point Tip-200pcs","offer_id":47850716496117,"sku":"14:366#Point Tip-200pcs","price":49.95,"currency_code":"USD","in_stock":true},{"title":"Point Tip-200pcs 1","offer_id":47850716528885,"sku":"14:10#Point Tip-200pcs","price":40.15,"currency_code":"USD","in_stock":true},{"title":"Point Tip-245pcs","offer_id":47850716561653,"sku":"14:496#Point Tip-245pcs","price":37.77,"currency_code":"USD","in_stock":true},{"title":"Point Tip-300pcs","offer_id":47850716594421,"sku":"14:200006151#Point Tip-300pcs","price":42.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/3494\/0149\/files\/S8613c070f9f149eab2741a9e4a025356S.webp?v=1773899621","url":"https:\/\/www.csldmcml.com\/products\/din914-304-stainless-steel-hex-socket-cone-point-set-screw-m3-m10-assortment","provider":"Cable Parts Online","version":"1.0","type":"link"}
