The Powerbuilt 12mm Honda Jam Nut Valve Tool closes the gap. This tool removes the frustration of improvising during a valve adjustment when precision is required. The classic case of the right tool for the job, if there ever was one. The 12mm jam nut and slotted valve adjusting tool makes precisely adjusting valves easy on Honda, VTEC, Toyota, Mazda, Nissan, and other vehicles with 12mm valve nuts. The window cutaway adds to the simplicity by allowing visual alignment of the screwdriver blade with the valve stud. While the 7 ½ -inch side handle provides the needed leverage to loosen those tight jam nuts. The package includes usage instructions and photos.","images":["https://cdn.shopify.com/s/files/1/0443/2681/3852/files/648828_20__1.jpg?v=1775123569","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/648828-1.jpg?v=1775123569","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/648828-2.jpg?v=1775123569","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/648828-3.jpg?v=1775123569","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/Valve_20Tool_81903fe0-c0b8-4e87-b469-dff929ce0b87.png?v=1775123569","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/648828-package.jpg?v=1775123569"],"price":29.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:27:11.070Z"},"share_url":"https://firestarter.network/l/lst_08_-g2qb","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
