T-nut M8 (copper) for mounting rails Rittal SV 9640.970, length 20 mm, pack of 15

Rittal T-nut M8 in copper is designed for secure mounting on electrical mounting rails and busbar systems, specifically for sliding into Maxi-PLS2 style collector rails. Each pack contains 15 copper T-nuts with a length of 20 mm, offering conductive contact and enhanced resistance to corrosion for reliable electrical and mechanical connections in control cabinets and distribution assemblies.

Advantages

Copper construction provides good electrical conductivity and natural corrosion resistance compared with common steel variants. The 20 mm length ensures a stable thread engagement for M8 fasteners while the T-nut profile is shaped for smooth insertion and positioning inside Maxi-PLS busbar sections. Supplied as a pack of 15, the set supports multiple mounting points and small assembly runs without frequent reordering.

Suitable for

• Securing components to Maxi-PLS2 type busbar and mounting rails
• Electrical cabinet assembly and distribution panel mounting
• Applications requiring conductive fastenings or reduced risk of galvanic corrosion
• Small to medium installation projects and maintenance replacements

When it may not be suitable

These copper T-nuts are intended for use with compatible collector rails that accept sliding T-profile fasteners; they may not fit proprietary or non-standard rail types. For applications requiring high tensile load ratings or where stainless steel is specified for mechanical strength, copper T-nuts could be less appropriate.

Key specifications

• Material: copper
• Thread size: M8
• Length: 20 mm
• Pack quantity: 15 pieces
• Designed for insertion into Maxi-PLS style busbar sections

How to use

Slide the T-nut into the side channel of the Maxi-PLS collector rail until positioned at the desired attachment point. Align the component to be mounted, insert an M8 bolt through the component and thread it into the T-nut. Tighten to the torque recommended for the application and bolt grade to ensure proper clamping without over-stressing the copper thread. For multiple attachments, space T-nuts and bolts evenly to distribute load and maintain electrical continuity where required.

What to consider before purchase

• Confirm compatibility with the busbar or mounting rail profile (Maxi-PLS2 type)
• Ensure M8 thread size matches mating bolts or studs
• Assess whether copper material meets mechanical strength and environmental requirements
• Determine required quantity for your assembly to avoid shortfalls

Usage recommendations

Use anti-seize or appropriate conductive compound if dissimilar metals are present to reduce galvanic effects; apply recommended torque values for M8 fasteners and inspect connections periodically for signs of loosening or corrosion in harsh environments.
