Frequently Asked Questions (FAQ)

1. What types of connectors does SN-58B support?
   DuPont/JST 2.54 mm, KF2510, MX-3.0 (small 5557), 3.2 mm/4.2–4.3 mm/5.08 mm lugs, VH/CH 3.96, Mini-Fit (5557/5559), SATA, small & large Tamiya (EL4.5/L6.2), 2.8/4.8/6.3 mm spade tabs, and various automotive open-barrel terminals within the tool’s die range.
2. Is this for open-barrel (F-crimp) terminals?
   Yes, it’s suitable for many open-barrel styles when the conductor/insulation sizes match the die cavity.
3. Does it work on insulated crimp terminals?
   It can crimp certain insulated types if sized correctly, but open-barrel terminals are its primary use case.
4. What wire sizes can I crimp?
   Use the die cavity that matches your terminal manufacturer’s recommended conductor range. Always confirm terminal datasheets.
5. How do I get a reliable crimp?
   Strip to the terminal’s specified length, seat conductor strands fully, choose the correct cavity, and perform a pull test after crimping.
6. Is it suitable for automotive harness work?
   Yes—within the supported terminal families and conductor sizes. Verify spec compliance for road/under-hood environments.
7. Can I use it for SATA power/signal terminals?
   Yes, provided the terminal size matches a supported cavity and you follow the terminal’s crimp spec.
8. Does it include interchangeable dies?
   No interchangeable dies are included; SN-58B is a fixed-profile mini plier. Use the appropriate model if you need swappable dies.
9. Maintenance tips?
   Keep the jaws clean, avoid excessive force on hardened parts, and apply a light oil to pivot points to maintain smooth action.
10. Is there a warranty?
    Yes—standard warranty terms apply. Retain proof of purchase and contact your seller for support.

Safety Note: Always de-energize circuits before crimping, follow terminal manufacturer specifications, and verify connections with a pull test.
