Notes:
All dimensions for metric sizes are in millimeters.
Click for here: CoilThread Weights Sizes
Notes:
1. Nominal length is a calculated number and cannot be measured in the free state. It is the actual installed length plus 1/2 pitch.
2. For Tangless CoilThread inserts, the number of free coils is the total number of convolutions (counted from notch to notch) and has a
tolerance of ±1/4 coil. For CoilThread (tanged) inserts, the number of free coils is the total number of convolutions and has a tolerance of ±1/4
coil. For all tanged Unified sizes, convolutions are counted by starting 90° from the tang. For all tanged Metric sizes, convolutions are counted
from the notch.
3. Tangless inserts are available for select UNC & UNF sizes up to 3/8", and select metric coarse sizes up to M12.
4. All dimensions for reference only.
