Our water works fastener line is also complemented by flanged joint bolts, bent eye bolts and a variety of fasteners (i.e. track bolts, saddle straps/bales) for pipe repair products, such as couplings, repair clamps, service saddles, and tapping sleeves.
Our galvanized square-head machine bolts, double arming bolts, forged eye bolts and lag bolts applied in power systems have become our another main product since 2005. All of these bolts meet ANSI C135.1 and are galvanized per ASTM A-153.
