Extension nut No. 6334 - M20 by AMF — SW 30 mm, 60 mm height

The Extension nut No. 6334 M20 is a compact extension nut designed to prolong M20 threaded connections for routine assembly, maintenance and clamping tasks.

• M20 thread for standard fittings
• SW 30 mm spanner access
• Overall height 60 mm
• Corner dimension 33.5 mm

Secure extension for standard threaded assemblies

The component provides a reliable method to extend a metric M20 connection without altering the original fastener arrangement. With a clearly defined M20 thread and an overall height of 60 mm, the part ensures that existing bolts and studs can be lengthened to meet assembly demands. This predictable, standardised geometry reduces the need for on-the-spot adaptations and minimises downtime in production or workshop settings. The feature helps maintain clamping integrity and avoids repeated rework, supporting efficient processes and measurable performance gains.

Simple, tool-friendly installation and practical handling

Installation is straightforward thanks to the SW 30 mm spanner flat, which allows access with common workshop tools. The specification of the spanner width is crucial: it permits controlled torque transfer during tightening, ensuring consistent clamping force and reducing the risk of over-torquing. The listed corner dimension of 33.5 mm assists in selecting clearance and tool profile during design or retrofit work. Supplied as a single unit, the part streamlines inventory management and facilitates immediate use in maintenance or assembly operations.

Suitable uses and reliability in everyday workflows

This extension element is intended for extending M20 threaded connections in routine industrial, trade and workshop applications where a short, robust extension is required. Its compact design makes it well suited to confined installation spaces while preserving the mechanical characteristics of the original fastener. The clear technical definition supports compatibility checks in procurement and planning phases, enabling procurement teams to make informed, low-risk decisions that maintain production continuity.
