Stainless Steel Inch Unc/Unf Size Helical Coil Screw Thread Insert

Product Description

_{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.}

<sub><sup>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.

Wire Thread Insert Material Types

Wire thread inserts are generally manufactured from SUS304 stainless steel (18-8), however inserts are available in a range of materials for special applications:
• Stainless Steel SUS 304 (AISI304)
Resistant Steel For normal applications. Temperatures ranging from -195˚C - 425°C (-320°F - 800°F)
• Stainless Steel SUS 316 (AISI316) Austenitic Corrosion
Resistant Steel For Marine applications up to 425°C (800°F)
• Inconel X - 750 Nickel Alloy. For high temperature applications 425°C - 550°C (800°F - 1020°F) or where low permeability is required.
• Phosphor Bronze (300°C)
For electrical bonding joints or low permeability
• Nimonic 90 for high temperature applications.
(650°C/1200°F)
• Nitronic 60 Austenitic antigalling alloy
