Designed with a 60° conical (bulge) seat and M12x1.25 threading, the set includes a 6-spline socket key so you can mount or remove the nuts without swapping tools. The dimensions and finish aim to suit many aftermarket wheels commonly fitted to vehicles such as Altima, Maxima and Forester.\n\n\u003ch3\u003eWill these lug nuts fit my vehicle and aftermarket wheels?\u003c\/h3\u003e\nThese nuts use M12x1.25 thread pitch and a 60° conical seat, which match many Japanese and some aftermarket wheel specifications. They are intended as replacements on various Nissan and Subaru models but always confirm the thread, seat type, and wheel lug hole clearance before purchase.\n\u003cul\u003e\n\u003cli\u003eM12x1.25 thread pitch\u003c\/li\u003e\n\u003cli\u003e60° conical (bulge) seat for compatible wheels\u003c\/li\u003e\n\u003cli\u003e0.67\" (17mm) hex, 1.38\" (35mm) length, 0.78\" (20mm) outer diameter\u003c\/li\u003e\n\u003cli\u003eIncludes 6-spline socket key for security and installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow durable is the finish and metalwork?\u003c\/h3\u003e\nMIKKUPPA applies a hardened black coating and cures it using infrared drying so the paint bonds tightly to the metal surface. The nuts are cold forged and heat treated for strength, and the finish is tested to withstand salt spray exposure so it holds up better against rust and corrosion than untreated parts.\n\u003cul\u003e\n\u003cli\u003e72-hour salt spray testing for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eInfrared-cured paint that resists chipping and flaking\u003c\/li\u003e\n\u003cli\u003eCold-forged, heat-treated steel construction\u003c\/li\u003e\n\u003cli\u003eClosed-end design helps shield studs from contaminants\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat installation and security features should I expect?\u003c\/h3\u003e\nThe set includes a 6-spline key that fits the nuts’ unique head profile to deter casual theft and simplify removal.

It’s a good fit for drivers who want a black, low-profile look, added stud protection through a closed-end design, and a more corrosion-resistant finish for vehicles exposed to wet or salted roads. Note: always verify wheel compatibility and factory specifications before replacing lug nuts.\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do these nuts fit original factory wheels?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: They fit wheels with M12x1.25 threads and a 60° conical seat; verify your factory wheel seat and thread before buying.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is a special tool required to remove the nuts?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: A 6-spline socket key is included; you can also use a 17mm socket for non-lock nuts but the key prevents casual theft.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"MIKKUPPA","offers":[{"title":"Default Title","offer_id":55166668833111,"sku":"B08334SSZ9","price":50.41,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/mikkuppa-front-view-packed-lug-nuts.jpg?v=1790369875","url":"https:\/\/britishgarage.co.uk\/products\/mikkuppa-m12x1-25-bulge-lug-nuts-for-nissan-subaru-20pc-black-closed-end-60-conical-17mm","provider":"British Garage","version":"1.0","type":"link"}
