Case hardened mild steel self-tapping threaded inserts
Our steel threaded inserts are made from high quality, EU sourced mild steel, case hardened zinc nickel plated and clear passivated finish. The insert is case hardened to increase strength and the zinc nickel layer helps to prevent corrosion.
The benefits of using steel thread inserts over brass depends on the alloy and application you are working with. Some steel alloys, for example, are stronger than brass whilst retaining quick machining and cycle times. Tappex threaded inserts can be directly placed into pre-moulded 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, both 303 & 316 grades with clear passivated finishes.
Stainless steels provide greater levels of resistance to corrosion that may be a direct consequence of coming into contact with acids and petroleum products. Stainless steels are typically harder wearing than mild steel. 316 grade offers an even higher level of corrosion resistance than 303. If your application involves contact with food or beverages certain grades of austenitic steel are FDA approved and so ideal for these applications. Tappex threaded inserts can be directly placed into pre-moulded and/or drilled pilot holes.
