GAsupply M12x1.25 Extended Open End Lug Nuts Black - 20 Pack + Key

In this review of the GAsupply M12x1.25 Extended Open End Lug Nuts, the bottom line is straightforward: these lug nuts are aimed at owners of aftermarket wheels who need a taller, open-end tuner style nut that looks good and resists corrosion. The reviewer found them to be a practical upgrade for wheels with 12x1.25 studs and a 60 degree conical seat, especially where a 48mm tall, 17mm hex tuner is required. Installation is straightforward when the fitment is correct, and the included dual-size key socket makes removal easy.

Key Features

• Thread Size: The m12 x1.25 thread matches wheels specified for 12mm x 1.25 studs, providing a correct mechanical fit when used with compatible aftermarket wheels.
• Extended Open End Design: The 1.9' (48mm) tall, open-end body allows extra clearance for wheel adapters or extended studs while keeping the lug secure.
• Durable Finish: The black electrophoresis coating resists rust and fading better than simple spray finishes, helping maintain appearance over time.
• Included Key Tool: The package includes a tall 75mm socket key with 3/4 (19mm) and 13/16 (21mm) drive tuner hex sizes, so the set is ready to install and remove.
• Material Construction: Made from through-hardened steel in a solid one-piece design, the nuts deliver reliable strength for daily driving and light performance use.
• Conical Seat Match: The 60 degree tapered seat ensures correct seating with wheel bolts that use a conical seat, improving clamping consistency.

Who It's For

This set is best for vehicle owners who run aftermarket wheels with 12mm x1.25 studs and require extended, open-end lug nuts for clearance or a tuner look. People using wheel adapters or extended studs will appreciate the 48mm height and open-end design.

It is not intended for vehicles with factory OEM wheels that do not use a 60 degree conical seat or that have a different thread pitch; buyers should verify stud size and seat type before purchasing to avoid a mismatch.
