【Anonymous Delivery】 【Instant Purchase OK】 【No Price Negotiation】 This is an extension bolt used for mounting a spare tire facing outwards on spare tire brackets for Jimny and Subaru vehicles, for mounting tires with aluminum wheels, and for using wider tires. Even if you don't usually use extension bolts, we recommend keeping them on hand with your tools. ※ Not compatible with JB64/JB74. Blackened products are rarely available, so this is a chance to get them only when they are listed. We also have glossy chromate and hexavalent chromate products. Dimensions 〈High Nut (Shaft)〉 Total Length: 30mm Width Across Flats: 19mm Internal Thread: M12 x P1.25 (Full Thread) Material: SS400, Black Oxide Finish 〈Stud Bolt〉 Total Length: Approx. 55mm M12 x P1.25 Rough Point Material: SS400 Steel 〈Lug Nut〉 Total Length: 17mm M12 x P1.25 Material: Chrome Plated (Iron) Taper: 60° Hexagonal Shaft Width Across Flats: 19mm The high nuts and lug nuts are blackened or plated, so they won't rust, but the stud bolts are made of untreated iron and require maintenance. You can maintain them using a lubricating rust-prevention spray like KURE556. Installation and maintenance are at your own risk. When installing, be careful of cross-threading the bolts and nuts. There may be some scratches or marks from the manufacturing or blackening outsourcing process. Please understand. The ends of the stud bolts may be rough, but we inspect all of them for thread insertion, so there are no problems with use. Photo 6 is an installation image. ※ When installing, gently screw in the bolts and nuts. If they catch, do not force them; remove them and try again gently. Forcing them can cause cross-threading, rendering them unusable. ※ We inspect all bolts before shipping. We cannot accept returns for any reason if the customer causes cross-threading. By purchasing, you agree to these terms. Disclaimer Installation photos are for illustrative purposes. Installation is at your own risk. We are not responsible for any damage to the vehicle body or traffic accidents caused by the customer's installation. JB23 Jimny Jimny Aluminum Wheels Custom Bracket Rear Tire Reversal Made in Japan
