Hong Nor #374 - 3x20 Left Hands Threaded

The Hong Nor HN#374 is described as 3x20 left-hand threaded, providing a reverse-threaded fastening for applications that require anticlockwise tightening. As a genuine Hong Nor spare, it offers a straightforward replacement option wherever a 3x20 left-hand thread is specified.

Left-hand (reverse) threads are commonly used to counter self-loosening in certain assemblies or where paired with a right-hand thread in adjustable components. If your build or maintenance notes call for a left-hand thread, the HN#374 aligns with that requirement in the 3x20 size designation.

For best results, refer to your model’s manual or build guide to confirm sizing and suggested compatibility before installation. Using the correct left-hand thread helps ensure secure assembly and reliable performance in RC maintenance and upgrades.
