Product Description

<sub>Screw Thread Insert (STI) Gauge

During the installation and use of screw thread inserts, the accuracy of the finished thread when the insert is installed is dependent upon the accuracy of the tapped hole. If the finished tapped hole gauges satisfactorily, the installed insert will be within the thread tolerance

STI gauges is used for checking accuracy of a tapped hole. The "NoGo" end of the gauge checks the pitch diameter is not too large and the "Go" end checks the pitch diameter is not too small.

Availabe sizes from inch UNC 2-56 to UNF1 1/2-12 or metric M2 to M30</sub>
 

Where to Use Wire Thread Inserts

Original Equipment Manufacture

The thread insert system enables to design high quality product using lighter weight materials such as aluminum and magnesium alloys while still achieving high strength and reliability in the threaded fastener assembly. Wire thread inserts are widely used by manufacturers in:
• Automotive, New energy vehicles
• Aerospace and Defense
• Industrial Electronics
• Consumer Electronics
• Ship Building and Transport
• Power Generation
• Manufacturing Equipment

Repair

When you encounter a damaged wire thread insert offers:
• Quickest and simplest method of repair to stripped or damaged
threads
• A superior thread with great holding power
• Most cost-effective method of repair
• Returns thread to the original size
• Generally stronger than the original female thread

Wire Thread Insert Type and Standards 

Wire thread inserts are available in either standard free running form or screw lock type which provides an internal locking feature.
Inserts are manufactured for every thread form including ISO Metric coarse or fine thread sizes, UNC/UNF/UNEF, BSW/BSF, ISO228/1 etc...
Inserts are available in 5 different standard lengths. 1D, 1.5D, 2D, 2.5D and 3D.
Special lengths can also be customized 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
