Case-hardened mild steel self-tapping threaded inserts
Our steel threaded inserts are crafted from high-quality mild steel sourced from the EU. They undergo case hardening and are zinc-nickel plated with a clear passivated finish. Case hardening enhances strength, while the zinc-nickel layer prevents corrosion.
The advantages of using steel thread inserts over brass depend on the alloy and application you’re dealing with. Some steel alloys, for instance, offer greater strength than brass while maintaining quick machining and cycle times. Tappex threaded inserts can be inserted directly into pre-molded and/or drilled pilot holes.
Stainless Steel self-tapping threaded inserts
Our stainless steel threaded inserts are made from high-quality EU-sourced austenitic steels, available in both 303 and 316 grades with clear passivated finishes.
Stainless steels offer superior corrosion resistance, especially when in contact with acids and petroleum products. They are typically more durable than mild steel. Grade 316 provides even higher corrosion resistance than 303. Certain grades of austenitic steel are FDA-approved, making them ideal for applications involving food or beverages. Tappex threaded inserts can be directly placed into pre-molded and/or drilled pilot holes.
