Lapp Skindicht SM-PE PG21 Brass Lock Nut, Chrome Plated

The Lapp Skindicht SM-PE PG21 is a high-quality brass lock nut designed for secure and reliable cable gland installation in industrial environments. Featuring a durable chrome-plated finish, this component is specifically engineered with integrated cutting edges that penetrate insulating layers, making it an ideal choice for EMC-compliant electrical applications where grounding is essential. Each pack contains 50 pieces, ensuring a consistent and professional supply for large-scale cable management and electrical infrastructure projects.

Advantages

The primary benefit of the Skindicht SM-PE lock nut lies in its specialized design which facilitates effective grounding. The integrated cutting edges allow the nut to bypass insulating layers, establishing a secure electrical connection between the cable gland and the housing. Constructed from robust brass with a chrome-plated surface, the nut offers excellent mechanical strength and resistance to environmental factors, ensuring long-term stability in demanding industrial settings. Its compatibility with PG21 threading makes it a versatile component for various standard electrical installations.

Suitable for

• EMC-compliant cable gland installations
• Industrial electrical panels and control cabinets
• Grounding systems requiring secure mechanical fastening
• Applications where insulating layers must be penetrated for electrical continuity

When it may not be suitable

This lock nut is specifically designed for PG21 threaded applications and will not fit components with different thread standards such as metric or NPT. It is intended for use with compatible cable glands and may not provide the necessary grounding functionality if used with non-conductive or incompatible housing materials.

Key specifications

• Thread size: PG21
• Material: Brass
• Finish: Chrome-plated
• Features: Integrated cutting edges for insulation penetration
• Quantity: 50 pieces per pack

How to use

To install the lock nut, thread it onto the cable gland after the gland has been inserted through the panel opening. Tighten the nut firmly against the enclosure wall. The integrated cutting edges are designed to bite into the surface of the housing or the insulating layer as the nut is tightened, thereby creating the required electrical contact for EMC protection. Ensure that the thread is properly aligned to prevent cross-threading and maintain the integrity of the connection.

What to consider before purchase

• Verify that your cable gland and enclosure opening are compatible with the PG21 thread standard.
• Ensure the housing material is suitable for the cutting edges to establish an effective ground connection.
• Confirm the quantity required for your specific project scale.

Usage recommendations

For optimal performance in EMC applications, ensure that the contact surface of the enclosure is clean and free of debris before tightening the lock nut. This ensures the cutting edges can effectively penetrate the insulation and establish a reliable electrical bond.
