If such a thin screw is exposed to corrosion, its load-bearing material thickness decreases rapidly, which can lead to the screw snapping under the slightest load. Acid-proof A4 steel (AISI 316 \/ 1.4401) contains molybdenum, which provides maximum resistance to pitting and crevice corrosion from salt water, condensation, capillary moisture, and chemicals. This guarantees that the M3 connection holds up over time.\u003c\/p\u003e","brand":"Rostfri.nu","offers":[{"title":"Default Title","offer_id":50996114096470,"sku":"101960","price":399.0,"currency_code":"SEK","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0776\/7864\/1494\/files\/rostfri-nu-m3-machine-screw-assortment-box.jpg?v=1786530558","url":"https:\/\/rostfri.nu\/en\/products\/maskinskruv-m3-sortimentsbox-720-delar","provider":"Rostfri.nu","version":"1.0","type":"link"}
