These nuts feature standard M3 metric threading and are universally compatible with any M3 machine screw, threaded rod, or standoff (both metal and nylon) used in electronics assembly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Are these stainless steel nuts magnetic?\u003c\/strong\u003e\u003cbr\u003e\nA: It depends on the specific manufacturing grade. Most common stainless steel fasteners (like 304 series) exhibit very low magnetic permeability after cold working, meaning they will be slightly magnetic but significantly less attractive to magnets than standard carbon steel hardware.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can these be used outdoors without rusting?\u003c\/strong\u003e\u003cbr\u003e\nA: Absolutely. The stainless steel composition offers excellent resistance against oxidation and corrosion, making them highly recommended for outdoor IoT sensors, weather stations, and damp environments where standard zinc-plated hardware would rust quickly.\u003c\/p\u003e","brand":"Generic","offers":[{"title":"Default Title","offer_id":49530566836462,"sku":"HTL-04796","price":0.35,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/M3_Hex_Nut_SS304.webp?v=1788432958","url":"https:\/\/www.tomsonelectronics.com\/products\/3mm-m3-stainless-steel-hex-nut-for-electronics-robotics-assembly","provider":"Tomson Electronics ","version":"1.0","type":"link"}
