- Make sure to select a proper oil filter screw size. Since both screw sizes are very close, M20 filter fits on UNF center bolt. If improper screw size is selected, it may cause the leakage of oil.
- What is UNF screw?
It is a triangular thread form by inch in the ISO standard. The thread angle is 60 degrees. It is classified by the suffix "UN".
The type of screw is described by a pitch as "Coarse" (UNC), "Fine" (UNF), "Extra fine" (UNEF). There is also one for aerospace equipment (UNJ). In Japan, use of this screw type is limited only for aircraft and automobiles, but it is widely used in the United States.
JIS employs only coarse (UNC) and fine(UNF) pitches.
This screw was initially designed for the millitary needs by the United States, the UK, and Canada.
