For NEMA 17 motors mounted through a 5–6mm aluminium plate, M3×12mm provides better thread engagement than M3×10mm.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eQ: Will M3×12mm bottom out in a NEMA 17 motor?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eA: NEMA 17 motors have M3 tapped holes approximately 4.5mm deep. With a 5mm motor mount bracket, M3×12mm leaves approximately 2.5mm of thread engagement in the motor — which is at the minimum recommended. For thicker mounts (6mm+), M3×12mm is the correct choice. Always verify your specific motor mount thickness before selecting screw length.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eQ: Can I use M3×12mm for aluminium extrusion T-slot assembly?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eA: Yes, for thick bracket assembly. Ensure the T-slot nut thread depth is sufficient for 12mm engagement. Standard M3 T-slot nuts have approximately 6–8mm of thread depth, so M3×12mm is suitable for brackets up to 4–5mm thick.\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"Keszoox","offers":[{"title":"Default Title","offer_id":45673211789547,"sku":"","price":13.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/Machine-Screw-M3x12-50-Pack.jpg?v=1723007639","url":"https:\/\/keszoox.com\/products\/m3-12mm-stainless-steel-phillips-pan-head-machine-screw-a2-50-pack","provider":"Keszoox","version":"1.0","type":"link"}
