The military specs for the breaking strength of dog tag chains is between 15 lbs and 32 lbs. My standard 2.4mm titanium chains with a steel connector break at approximately 28 lbs. These beaded chains work well with my titanium dog tags which can be seen here.
If you need a length shorter or longer than what is available in the drop down menu, please send me a message for a custom invoice.
*Note: 4mm chain has a breaking strength of about 90 lbs. Because of this, the 4mm chain is not intended for children or in cases where the chain could get snagged or pose a choking hazard.
