ORIGINAL LUG NUTS
Tough and tightening the foot of 4x4s
4x4 Engineering Service's original lug nut series
Toughness and high quality are combined in 4x4 Engineering's original lug nuts.
This original lug nut combines the toughness required of a lug nut with a simple and beautiful shape. The original lug nuts were designed based on the concept of "quality and solidity" to tighten up the wheels of 4WD vehicles.
Original rug nuts available in two materials
Competition Lug Nut
Competition lug nuts are SCM435 forged; SCM435 is a type of chrome molybdenum steel.
Chrome molybdenum steel is one of the most tenacious of steel materials and is characterized by its resistance to torsion. It is also characterized by its beautiful finish.
4x4 Engineering's Competition Lug Nut is a rug nut product that beautifully enhances the toughness required of a rug nut with black paint and emblems.
Titanium Lug Nut
Titanium lug nuts are made of Ti64, a titanium alloy widely chosen for aircraft and automotive parts.
Ti64 is known as a high-grade metal material because of its toughness and strength, its high corrosion resistance, its resistance to rust, and its light specific gravity, which makes it lighter and easier to use than ordinary iron.
4x4 Engineering's Titanium Lug Nut is the perfect lug nut product, combining the strength and beauty required in a premium lug nut.
Competition Lock Nuts to Protect Your Valuable Wheels
Competition Lock Nuts are lock nuts developed with a commitment to Japanese manufacturing, just like the BRADLEY Series.
The 4x4Engineering logo design is laser-engraved on the nut top/side. Made from chromoly steel, renowned for its hardness and strength, it delivers a high-quality finish befitting the Bradley series.
Installing a competition lock nut enhances the security of your valuable wheels.

[Attention.] These nuts are for 60° taper wheels only. Never use this nut on wheels with spherical or flat seats. The vehicle mounting surface and hub bolt must be free of rust, dirt, and deformation. The diameter and thread pitch of the hub bolt and nut must match those of the vehicle.
[Warning.] *Do not install the wheel if the nut threads cannot be tightened more than 10 mm when the wheel is installed. The tightening torque for this nut is 110 to 120 N・m (11 to 12 kgf・m). *Tightening torque is for reference only. Priority for tightening should be given to the torque specified by each manufacturer. Overtightening or under-tightening of the nut may cause deformation or loosening of the wheel, hub bolt, etc., resulting in an accident. Translated with www.DeepL.com/Translator (free version)。
[confirmation] The installation nut is likely to loosen at the beginning of installation or after rotation, so retighten it after about 100 km of driving. If the product is left for a long time with mud or other contaminants adhering to it, the gloss may become uneven. In addition, anti-icing agents on roads in snowy areas and salt water and sea breezes in coastal areas can cause rusting, so please be sure to wash them with water after driving. Please note the key number in case of emergency. Translated with www.DeepL.com/Translator (free version)
