High Technology Bolting Products

We carry a full line of anchor bolts from 5/8" to 2+" in any length. From a standard one-piece bolt to a new high strength two-piece canister bolt. We can manufacture common or custom designed bolts to solve your bolting problems.

All of our bolts are subjected to stringent quality control standards. Each bolt is visually inspected, with a ring gage, and stamped with a serial number that is traceable back to the original mill run.

Our custom designed canister bolts allow the bolt to drop below grade while the equipment is skidded onto the foundation. Lateral and angular misalignment correction is a safety feature built into our custom canister design.

RotaBolt Load Monitors, which provide a simple check of whether the bolt has maintained its designed torque, are available and can be set for your specific needs. Providing ± 5% accuracy, and so simple to use, the RotaBolt is an indispensable part of any anchor bolt preventive maintenance program.

Superbolt tensioners are designed as direct replacements for hex nuts. They can be threaded onto a new or existing bolt, stud, threaded rod or shaft. The main thread serves to position the tensioner on the bolt stud against the hardened washer and load-bearing surface. Once positioned, actual tensioning is accomplished with simple hand tools by torqueing the jack bolts that encircle the maim thread.

From reciprocating compressors, pumps and skid mounted equipment to cranes, presses or crushers, if you need to anchor equipment, Robt. L. Rowan & Assoc., Inc. has a bolt to meet your specific needs.
