{"product_id":"small-diameter-spline-acorn-lug-nuts-black","title":"Small Diameter Spline Acorn Lug Nuts, Black","description":"The Gorilla 21138BC small diameter spline acorn lug nuts provide a durable and secure solution for mounting aftermarket wheels. Engineered with a 12mm x 1.50 thread pitch and a 60-degree conical seat, these nuts are heat-treated for enhanced strength and finished in black for a sleek appearance. Their compact 20mm outside diameter and small hex size are specifically designed to fit within tight lug nut pockets on many aftermarket wheels, often requiring a specialized spline key (sold separately or included depending on the specific package) for installation and removal.\n\nThe overall length measures 1.36 inches, providing sufficient engagement with the wheel stud. It's important to note that these lug nuts are intended for most aftermarket wheels and may not fit original equipment factory wheels. Customers are responsible for confirming fitment with their specific vehicle and wheel combination, as fitment data may not always be readily available for all applications.","brand":"Gorilla","offers":[{"title":"Default Title","offer_id":52688579002680,"sku":"21138BC","price":1.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687901931.webp?v=1784891333","url":"https:\/\/store.motormia.co\/products\/small-diameter-spline-acorn-lug-nuts-black","provider":"MOTORMIA","version":"1.0","type":"link"}
