Locknut M20 polyamide 6 glass-filled flanged black ITC Electrical 184.120
M20 flanged polyamide locknut for securing metric cable glands and accessories to panels and enclosures. Glass-filled PA6 construction and the flanged profile provide a larger bearing surface that is commonly used to help support a secure fit on non-threaded entries.
What this product is for
This M20 flanged locknut is used to secure compatible metric cable glands, threaded accessories, and enclosure entries from the inside of a panel or cabinet. It is intended for electrical enclosures, control panels, machinery, and similar industrial or commercial installations.
Use for
- Securing M20 metric cable glands on non-threaded panel holes
- Control panels, junction boxes, machine enclosures, and automation equipment
- Applications where a wider bearing surface is preferred over a non-flanged locknut
Avoid for
- Thread sizes other than M20
- Applications requiring a metal locknut for higher mechanical or temperature demands
- Installations where the enclosure entry is already threaded and a locknut is not required
Best for
Best for electricians and panel builders who need a plastic locknut for an M20 cable gland entry with added contact area at the panel surface. The flanged design is commonly chosen where cutout irregularities or surface support are a concern.
Installed in
Typically installed inside electrical enclosures, cabinets, pull boxes, and equipment housings. Commonly paired with plastic cable glands in industrial and light commercial control applications.
Why this product exists
A flanged locknut helps retain a cable gland or threaded accessory when the enclosure hole is not tapped. Compared with a standard non-flanged style, the flange provides a larger contact surface that can help with fit and support at the panel wall.
Compared with similar products
- Compared with non-flanged plastic locknuts, this style provides a larger contact area
- Compared with metal locknuts, polyamide offers a non-metallic option for compatible installations
- Typically selected to match M20 x 1.5 metric cable gland threads
