Product Shall be Marked with our manufacturing trade mark "TorqBolt" or "TB"
along with the
designated Grade.
Grade and manufacturer’s identification symbols shall be applied to one end of
studs and to the heads of bolts
and screws of all sizes. (If the available area is inadequate, the grade symbol
may be marked on one end and
the manufacturer’s identification symbol marked on the other end.) For bolts and
screws smaller than 1⁄4 in.
[6 mm] in diameter and studs smaller than 3⁄8 in. [10 mm] in diameter and for
1⁄4 in. [6 mm] in diameter studs
requiring more than a total of three symbols, the marking shall be a matter of
agreement between the purchaser
and the manufacturer.
