Aztec Bolting carries only quality flange spreaders that are fundamental to critical bolting applications. The need for reliable flange spreaders is crucial in the field or in the shop. We offer a mechanical 8-ton wedge that has the advantage of operating without a hydraulic pump; this is ideal for wind turbine and other field applications. Aztec also provides a 10-ton hydraulic wedge and the Enerpac FS-Series Hydraulic Flange Spreader.

Aztec Bolting also carries a revolutionary integral hydraulic flange spreader that one person can carry and operate, complete with a shoulder strap for easy transport. This is new generation tooling for your critical bolting application.
