Flat Head Step Rivet

Our flat head step rivet is specially designed for car wiper arms. It features a flat head and a precision step. The flat head does not interfere with wiper arm movement, while the step ensures consistent rivet height. These rivets are used in wiper arm assemblies, linkage mechanisms, window lifters, and door checkers where precise height matching is critical.

A leading wiper motor manufacturer approached us because one or two of his rivets often had varying heights after assembly, resulting in poor wiper blade performance. We supplied our flat head step rivet with a step height tolerance of ±0.02 mm. All rivets now achieve the same height, providing even wiper blade pressure. This manufacturer now holds 30% of the domestic wiper motor market. His comment: "Jieyi's rivet is the soul of the wiper."

With 16 years of cold heading experience, our precision is among the best in the industry. You provide the design, and we help you realize it.

Our flat head step rivet has a head diameter 1.5–2 times the shaft diameter and a head thickness of 0.5–1.5 mm. Step length and diameter are customized according to your drawing.

We follow the highest automotive industry standards. Size tolerance is IT8 grade, critical assembly dimensions are ±0.02 mm, and concentricity is within 0.02 mm. Carbon steel hardness is HV260–320, and tensile strength is at least 1040 MPa. Fatigue life is rigorously tested, withstanding 10⁶ cycles without failure-meeting the standard for moving parts such as wiper arms. You can rely on its performance with confidence.
