36mm Extension Nut M12 SW18mm Eckenmaß 20.03 - AMF

Take advantage of a standard M12 threaded solution with a 36 mm overall height and an SW 18 mm hex for familiar tooling; the result is faster, more consistent assembly of metric connections. Order the AMF extension nut directly via Metav Werkzeuge or consult our advisers for compatibility guidance.

Extension nut No. 6334 — M12 (AMF) with 36 mm height

The Extension nut No. 6334 M12 serves as a threaded joining piece for extending or coupling metric M12 connections in assembly and maintenance tasks across workshops and industrial settings.

• M12 thread for standard metric connections
• 36 mm overall height for extended reach
• SW 18 mm hex for common spanners
• AMF quality for industrial use

Secure, repeatable threaded joins for metric assemblies

A compact extension nut provides a dependable means to couple or extend M12 threaded components. The metric M12 specification ensures compatibility with common studs and bolts used across mechanical, electrical and fabrication work. By relying on a standardised thread size, procurement and inventory management are simplified, while assembly processes benefit from repeatable mechanical engagement and predictable torque behaviour. The short profile still offers reliable engagement without excessive protrusion.

Familiar tooling speeds up installation and maintenance

Designed with an SW 18 mm hex, the component accepts widely available spanners and sockets, allowing technicians to use existing tools and minimise changeover time. The hex dimension supports conventional torque transmission without requiring specialist equipment, which reduces the time needed for tightening and rework. Where line-side efficiency matters, the compatibility with standard tools translates into lower labour overheads and fewer interruptions during scheduled maintenance.

Extended reach for confined or raised connections

The 36 mm overall height provides modest extension where extra thread length is required to bridge gaps or to allow secure engagement on short studs. In constrained assemblies, the added length can prevent cross-threading during initial engagement and facilitate safer, more accurate hand starts before final torque is applied. When space is limited or accessibility is restricted, a dedicated extension component improves assembly ergonomics and reduces installation errors.

Consistent specification and traceability for workshop planning

Supplied under the AMF designation and listed with SKU 4000833424NW, this extension nut supports orderly stock management and traceability for repair orders and production runs. The clear dimensional data—thread size, hex width and overall height—helps planners verify fitment quickly and select appropriate mating parts. Incorporating standardised components like this into a bill of materials reduces procurement complexity and supports predictable lead times on the shop floor.
