About K.L.Jack

Humble Beginnings

It all started in 1979 with the vision to stock the finest industrial nuts and bolts to our local Maine customers. KL Jack established its reputation as a business that never took shortcuts and made sure to always offer the best quality hardware on the market.

Just three years later, the veteran- and family-owned company set up its headquarters in Portland, Maine. Since then, we have grown at an annual rate of more than 25%.

“For nearly three decades, K.L. Jack has supplied [us] with fasteners, drill bits, saw blades, and other supplies.”
