Second, there is no tang for locking. TIME-SERTs use a special tool to lock the bottom threads into the threaded repair hole. Since TIME-SERTs are a solid body, thread locking compounds can be used on the inserts outer threads for additional strength without it affecting the inside threads and fastener.
Why are the threads lined up on the outside of the insert?
By keeping the threads lined up on the inside and outside of the insert, the cross-sectional-area or wall thickness can remain consistent. The result is the ability to maximize strength for a given outside diameter of insert.
Which is better TIME SERT or helicoil thread repair insert?
While TIME-SERTs offer advantages over other thread repair insert designs, it also has a few drawbacks. First, it’s about twice the price of a HeliCoil per insert. Second, it must be installed directionally, as its flanged-design requires the non-flanged side to be threaded in first.
What to do when cast iron thread is damaged?
When thread damage does occur in cast iron and steel, the most common practice is to drill out the existing threads and tap the hole to accept a larger fastener. In many cases, this solves the problem. When the same size fastener must be used, an insert can be installed to save the day.
What are the dangers of using threaded inserts?
Using bolts made out of stronger and harder materials with soft metal threads also increases the risk of damaging the threads. Corrosion – rust and corrosion causes threads to become weaker and breaks it down much quicker. Incorrectly sized bolts – using bolts that are too large or too small can damage threads just like over or undertightening.
How are thread inserts used in thread repair?
When properly installed, inserts provide high-quality, wear resistant, permanent internal threads. In many situations, thread inserts are ideal to repair stripped threads. Thread inserts are also commonly used in new part designs because of the many benefits that they offer. Thread inserts are supplied in a variety of configurations.
Is the thread on an insert the same size as the tap?
The internal threads have the exact same size of the thread that you are trying to repair. For example, an M10 x 1.5 threaded insert will fit a 10mm bolt with a 1.5mm pitch.The threads on the outer surface of the threaded insert are the same size as the tap that’s included in the kit, and will be a little bit larger than the original thread.
