Flanged locknut · 1/2 in NPT · black polyamide 6 · ITC Electrical 184.150
1/2 in NPT flanged locknut for securing cable glands or threaded fittings to panels and enclosures. Black polyamide 6 construction is commonly used where a non-metallic locknut is preferred for corrosion resistance and electrical isolation.
What this product is for
This 1/2 in NPT flanged locknut is used to secure compatible cable glands and threaded fittings to panels, boxes, and enclosure walls. It is a non-metallic fastening accessory for electrical and control panel work where a plastic locknut is preferred.
Use for
- 1/2 in NPT cable glands and threaded fittings
- Panels, junction boxes, and enclosures with unthreaded entries
- Industrial and commercial installations requiring a black non-metallic locknut
- Applications where corrosion resistance or electrical isolation is preferred
Avoid for
- Thread sizes other than 1/2 in NPT
- Applications requiring a metal locknut for bonding or specific mechanical requirements
- Installations where space does not allow a flanged profile
Best for
Electricians and panel builders matching a 1/2 in NPT plastic cable gland or fitting with a flanged locknut for better bearing surface against the enclosure wall.
Installed in
Commonly installed in control panels, machine enclosures, junction boxes, and other electrical cabinets. The flanged design provides a larger contact area than a standard non-flanged locknut, which is typically helpful on panel cutouts and uneven surfaces.
Why this product exists
When a panel opening is not threaded, a locknut secures the fitting from the inside of the enclosure. A flanged polyamide locknut offers a non-metallic option with good mechanical support and resistance to many common industrial conditions.
Compared with similar products
Compared with a non-flanged locknut, this flanged version provides a larger contact surface. Compared with a brass locknut, a polyamide locknut is typically chosen where lower weight, corrosion resistance, or electrical isolation is preferred. Actual suitability depends on the fitting, enclosure material, and installation conditions.
