Round Trapezium Threaded Nuts (DIN 103)

Round Trapezium Threaded Nuts to DIN 103 standard, commonly referred to as Cylindrical Trapezoidal Nuts, feature a circular body with an internal trapezoidal thread – one of the strongest symmetrical thread profiles currently available.

They are fastened onto matching Trapezoidal Threaded Rod and are typically used to generate power through motion. When rotated around a thread, this creates a linear motion that is essential in many industrial assemblies e.g. CNC machines.

Featuring a 30° thread angle, this component is suitable for high torque applications, offering great strength and load bearing capabilities – ideal for heavy duty work. Hexagon Trapezium Threaded Nuts are also available at Fastenright.

Round Trapezium Threaded Nuts to DIN 103 are manufactured from Steel, A1 Stainless Steel and Bronze as standard. Other materials and finishes are available to order.

Available now with thread sizes from 10mm (TR10x2) to 80mm (TR80x10). We supply a huge range of Threaded Rod and Nuts here at Fastenright.
