They're not stamped "Made in US", but these are the same quality as the other dozen of keyed-alike Master padlocks I own. (Coded with key #2002). A local NH locksmith got them for me after I'd freshly acquired a
BMW 2002.
However, I've got a big project needing a couple of pounds of 1/4" diameter stainless steel 4" lags and 6" bolts, if a trade can be made for the difference.
