Product Description

Car Wheel Bolts are key fasteners that connect the wheels to the hub unit bearings, carrying the weight transmission and driving torque output of the entire vehicle. Unlike the two-piece "hub bolt+nut" structure, the hub bolt is a long screw that runs through the aluminum alloy wheel rim and brake disc, and is directly screwed into the threaded hole of the hub flange.

In terms of installation and maintenance, both wheel hub bolts and bolt type structures have their own advantages and are equally reliable. However, due to the design of wheel hub bolts as a single piece structure with only one threaded interface, the failure probability under extreme working conditions is theoretically lower than that of the two-piece type.

Product Feature

Alloy steel material, stable performance: Made of 40Cr or 35CrMo alloy steel, processed by quenching and tempering heat treatment and rolling process, with a thread accuracy of 6g and full inspection of the pass stop gauge. The hardness and torque coefficient are controlled within the standard range to ensure smooth and reliable installation.

Dacromet surface treatment, high rust prevention level: Wheel hub bolts are exposed to the outside of the wheel for a long time, and are exposed to corrosive environments such as water, mud, sand, and snow melting agents. The rust prevention effect of Dacromet coating is 7-10 times that of traditional galvanizing, and the salt spray test can reach more than 1200 hours without red rust, and there is no risk of hydrogen embrittlement - especially important for high-strength bolts above grade 10.9. Phosphating treatment can also be provided according to customer requirements.
