M12x1.5 Bulge Acorn Wheel Lug Nuts

Key Features

Advanced Forming Technology: Utilizing a cold heading integrated forming process, compared to stamping, it reduces material waste, increases product density, leaves metal fibers intact, resulting in a more stable internal structure, longer service life, and a material utilization rate exceeding 80%.

High Thread Precision: Threads are processed using a fully automated tapping machine, resulting in smaller thread dimensional errors, more uniform pitch, and no residual waste in the hole compared to manual tapping. This enhances installation adaptability and effectively avoids jamming and stripping issues during installation.

Reliable Surface Quality: Equipped with a fully automated electroplating production line, it employs electroplating, electrophoresis, and Dacromet surface treatment processes. Custom colors can be provided according to customer requirements, ensuring a smooth, flawless surface with excellent corrosion resistance. It easily passes a 72-hour salt spray test, meeting the requirements of the QC/T 625-2013 industry standard.

Stable Hardness: The M12x1.5 Bulge Acorn Wheel Lug Nuts undergoe professional heat treatment, achieving a stable hardness of 8.8, capable of withstanding various impacts during vehicle operation. It meets the strength requirements for fixing automotive wheel rims, eliminating safety hazards such as nut breakage and deformation caused by insufficient hardness.

Complete Specifications: Standard hexagonal sizes include 17mm, 19mm, 21mm, 22mm, and 24mm, compatible with wheel rim removal tools for different vehicle models. No additional wrenches are needed, making it more convenient to use.
