Overview

U-Nuts - Packs

Shape: Hex nut
• Locking Type: U Nut

• Thread Ridge Type: Metric Coarse

Product Description

The locking principle of 980-m nut is as follows: the nut is embedded with a metal sheet after heat treatment, the inner diameter of the metal sheet is slightly smaller than the outer diameter of the bolt thread. After the nut is tightened, the metal sheet will block the bolt thread, which can effectively play the role of anti loose and anti-seismic.

DIN 980M Installation method

The lock nut must be tightened with tools (such as ratchet spanner) during installation. It is recommended to pre coat the stainless steel nut with grease to prevent the nut from locking during rapid installation.
