Heli Coil Gauges

Offered in multiple types and fit for several thread sizes, Heli-Coil® thread gages from Olander are a must-have in your fastener supply collection. A Heli-Coil® thread gage is used to determine whether a tapped hole is the correct size. If you place the gage in your tapped hole and it fits, you have a big enough hole. If it doesn't fit, your hole is too small. To avoid uncertainty from the get-go when it comes to questioning the size of your tapped hole, proactively using Heli-Coil® thread gages can help save you time and labor. Work confidently and efficiently with a Heli-Coil® thread gage.
