Product Overview
Manufacture precision electrical fittings with our PG (Panzergewinde) Full Profile laydown threading inserts. Compliant with DIN 40430 standards, these tools produce the unique 80° thread angle used extensively in electrical conduit systems, cable glands, and connectors across Europe and Asia.
Featuring a “Full Profile” geometry, these carbide threading inserts cut the shallow thread depth and finish the crest radius in a single pass. This ensures the thin-walled conduit pipes maintain their structural integrity while providing a secure, vibration-resistant connection.
Key Features & Benefits
- 80° Profile: Precision ground to the exact 80° included angle, preventing cross-threading with standard 60° fasteners.
- The 16ER Standard: Our 16er threading inserts (e.g., 16ER 18 PG) efficiently handle the most common conduit sizes (PG9 to PG16) in a single tool.
- Small Bore Capability: We offer 1/4″ (11mm) I.C. inserts for threading smaller internal glands and connectors.
-
Directional Options: To support complex manufacturing, we provide standard right-hand tools and specific left hand thread insert models (e.g., 16EL 16 PG) for special fittings.

Machining Guidelines
- Unique Angle: PG threads use an 80° included angle. Do not attempt to machine these using standard 60° or 55° threading inserts for lathe holders without checking anvil compatibility, though standard laydown holders are generally compatible due to the shallow depth.
- Thin Walls: PG threads are often cut on thin-walled conduit tubing. Ensure your clamping pressure is regulated to prevent tube deformation during machining.
-
Finish: As Full Profile laydown threading inserts, these tools top the crest to ensure the fittings mate smoothly without damaging o-rings or seals.
