Domestic T Thread Hollow Bars

We have noticed an increased demand of domestic Hollow Bar which has resulted from both Buy America clauses and the acceptance of Hollow Bars as permanent applications.

We have noticed an increased demand of domestic Hollow Bar which has resulted from both Buy America clauses and the acceptance of Hollow Bars as permanent applications. Skyline Steel offers domestic Hollow Bar in T40/20, T40/16, T52/26, T76/51, T76/45 and 103/78. We've decided to roll our product using the T thread due to its robust shouldered thread which can handle the impact of today's percussion drills and high torque outputs. Our competitors' product offering consists of a very finely threaded Hollow Bar which tends to cross thread, resulting in tooling damage or loss. The T thread is now standard in the market and matches up with installer's tooling, striker bars and grout swivels.


Furthermore, Skyline Steel is the first to offer numerous domestic Hollow Bar bits for stepped clay, carbide cross cut and carbide button. All domestic Hollow Bar products are made and melted in the USA.
