Time-Serts are called "thread inserts" and are thin walled threaded sleeves generally made of steel. They have a screw thread on the inside and also on the outside and the "peak" or hill of the inside thread nests into the peak of the outside thread. This is how Time-Serts succeed in making the wall of their inserts extra thin.
Time-Serts are used for repairing stripped threads or in manufacturing to create stronger new threads in soft materials like aluminium or plastics. Because Time-Serts are so thin walled they take only a minimum amount of material around any hole needing to be repaired or inserted.
You will need a special set of tools for each size of Time-Sert you want to use. You can buy all the tools you need with a starter supply of Time-Serts in a ready made kit (pictured at left). You can only fit one diameter and type of thread insert with each kit. Usually the kit contains (1) a drill (of the correct size to drill out the hole to be repaired or strengthened) - (2) a special tap to retap the hole to the right size for the Time-Sert - (3) a "counterbore" to cut a recessed lip which takes the flange of the Time-Sert - (4) an "insert driver" to screw the Time-Sert in and lock it in place and (5) a starter supply of Time-Serts (usually a quantity of 5).
First of all, to explain how Time-Serts work, you need to know that a Time-Sert has extra metal left in the bottom internal threads when it is made. This means the bottom inside threads are not fully formed. (You can see this inside the black ring in the picture at left).

The yellow tool pictured above is the Time-Sert driver tool. It is a fluteless, roll forming tap. As it is screwed through the Time-Sert it roll forms the bottom internal threads that had extra metal left in them during manufacture. This locks the Time-Sert into the "Base Material" by forcing the extra metal in these threads outwards.

For size listing and further details go to:
(1) (2) (3) (4) (5)
(1) Drill with the drill supplied in the kit.
(2) Counterbore the hole with the tool supplied. This makes a recessed lip
in the base material for the flange of the Time-Sert.
(3) Tap the hole with the special size tap supplied in the kit.
(4) Screw the insert in with the insert driver supplied until you have gone
right through the insert and rolled formed the inside bottom threads.
(5) The Time-Sert will now be in place seated below the surface in the lip
you made with the counterbore tool.
Big-Sert Kits come in both metric and imperial sizes and contain all the tools you need to do a Big-Sert repair and usually 5 standard length Big-Serts.
Your second chance at thread repair.
Pictured on the left is the insert you can use if you've come across a threaded hole that's already been repaired with a Helicoil or Time-Sert and the "first time" repair has stripped out. Big-Serts are a thick walled version of Time-Serts. Kits are available with the necessary tools to do a Big-Sert repair in a range of popular thread sizes.
