Absolutely the strongest we have found in this size range.
This clasp is:
5.5mm diameter X 20mm, including 5mm spring rings
7/32" X 13/16", these add 3/4" to items a penny coin is 19mm
In our opinion, suitable for chains up to 40grams. You be the judge for yourself. No hassle returns.
Spring ring and other clasps WILL be slightly attracted to the magnet, as their internal springs are steel. Rest assured these are solid 14k GOLD FILLED
NOT responsible for any damage or losses due to clasp failure.
USE AT YOUR OWN RISK if you use a PACEMAKER, INSULIN PUMP, OR DEFIBRILLATOR etc...Thanks
