DIN 74361 A 8 zinc Spherical hexagonal nut with flange and fine pitch

Overview

DIN 74361 A 8 with a zinc coating is a hex wheel nut with a form A flange, designed to help center the part relative to the fastener axis. It is made of quality steel and meets strength class 8, providing reliability under appropriate mechanical loads. The zinc coating provides additional corrosion protection.

A flange nut is a fastening element that creates a detachable threaded connection with an increased clamping area. This helps distribute pressure over the material and improve connection stability. DIN 74361 is often referred to as a wheel nut because it is most commonly used in mechanical engineering for wheel fastening.

The DIN 74361 standard includes several design forms: a conical flange, form A, which helps center the part on the axis by seating the cone in the wheel disc hole; a standard flange, form B, similar in purpose to flange nuts such as DIN 6331; and form H — a version with a flange that is an integral part of the nut but can rotate relative to the nut body.

Fine thread nuts provide more precise and smoother adjustment during tightening and can be used for parts where high connection accuracy is required.

Applications

The DIN 74361 A 8 nut with a zinc coating has a form A flange that helps center the connected parts relative to the fastener axis. This makes it suitable for applications where accurate seating, reliability, and connection stability are important, such as automotive applications, suspension systems, leaf spring fastening, commercial vehicles, and trailer equipment.

Thanks to its flange design, the nut provides an additional contact area and helps distribute the load evenly. It is made of steel with a zinc coating that provides additional corrosion protection and is suitable for standard operating conditions, including increased humidity.

Technical Specifications

Please note: the product color may vary depending on the production batch — black or gray. This does not affect the technical specifications or product quality.
