Thread inserts are formed from high quality stainless steel wire with a diamond shaped cross section, wound to the shape of a spring� thread. Once the wire is wound into a helical coil and installed into a tapped hole, it provides a permanent and wear resistant thread in� the parent material that is generally stronger than the original thread. The thread inserts are designed to be greater in diameter than the tapped hole and compress as they are installed. This allows maximum surface contact area with the tapped thread, safely and permanently� anchoring the inserts into place. The insert's compensatory action shares the load over the entire bolt and hole, increasing pull out and� torque out strength. With a thread insert in place, load and stress are more evenly distributed over the assembly.
Thread inserts: Where to use?
Original equipment manufacturer
Thread insert offers innotive way for manufactuer to design and produce high quality products using lighter materials such as aluminium die casting and magnesium alloy parts. While can still achieve high strength and reliability in assembly.
It is widely used in manufacture of following industries:
1. Aerospace and defense
2. Ship building industry, high speed train and other transportation
3. Automotive industry especially new energy automotive
4. Industrial and consumer electronics
5. High precision industrial parts
6. Aluminium die casting and magnesium alloy parts
Thread repairing
Thread insert is a ideal and simplest way for repairing stripped or damage threads.
Qualicoil thread inserts are available in either standard free running form, tangless or screw lock type. Qualicoil thread inserts� are manufactured for every thread form including UNC, UNF, ISO Metric thread sizes. Inserts are available in 5 different standard lengths
1D, 1.5D, 2D, 2.5D and 3D. Special lengths are available on request.
We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.
