Noticed :
- Threads
#6-32 and #4-40 fall under the UNC standard (coarse pitch).
- The
#6-40 thread corresponds to the UNF standard (fine pitch).
- The
#6-48 thread is classified as UNEF (not extra-fine).
- Metric screws (M3, M3.5, M4) conform to the ISO standard (pitch 0.5, 0.6 or 0.7 mm).
Key Strengths
