About Us

Aztec Bolting Services Inc. recently expanded to a new facility in League City's Historical District. We are a service oriented company with 35 years experience in turnaround & plant construction. We provide experienced field technicians and/or hydraulic tooling for the purpose of controlled bolt tightening in critical bolting applications.

This service is typically performed with the use of hydraulic torque wrenches and/or bolt tensioning equipment. Our services are presently utilized in by petrochemical plants, refineries, power generating facilities, offshore drilling contractors, in specialty manufacturing and heavy industry.

The utilization of hydraulic tools allow for a safer and faster means of the breakout of large or frozen bolts as well as a highly accurate means of tightening those same bolts. When you consider the importance of ensuring the integrity of the bolts, seals, flanges, and process equipment, hydraulic tools can help you realize a huge potential savings in manpower and equipment cost.

Our trained technicians can do the job for you or work with your labor force to assist with any job you may have. Our safety record is outstanding with written company safety and drug policies in effect. No job is too big or too small. We take all our jobs very seriously.

In addition to providing bolting services, we also provide bolting equipment for sale and/or for rent. We maintain a sizable inventory of tools, pumps, large impact sockets, stud removal tools and other related accessories. We represent the best manufacturer of specialized bolt tightening equipment and related accessories and offer most for rental.
