Check your specific extrusion profile’s T-slot channel width to determine the correct nut and screw size.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eQ: What Phillips screwdriver size do I need for M4 screws?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eA: M4 pan head screws use a Phillips #2 (PH2) screwdriver. Using a #1 will cause cam-out and strip the head. A magnetic tip screwdriver is recommended for accurate placement.\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"Keszoox","offers":[{"title":"Default Title","offer_id":45673226764523,"sku":"","price":23.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/Machine-Screw-M4x8-50-Pack.jpg?v=1723007624","url":"https:\/\/keszoox.com\/products\/m4-8mm-stainless-steel-phillips-pan-head-machine-screw-a2-50-pack","provider":"Keszoox","version":"1.0","type":"link"}
