Williams Comfort Products AS404STR Hydraulic Nut Splitter

Product Description

The WILLIAMS COMFORT PRODUCTS AS404STR is a hydraulic nut splitter designed to remove seized, corroded, or frozen nuts quickly and without damaging the bolt or stud threads beneath. The tool applies controlled hydraulic force through a precision-ground cutting chisel, splitting the nut in seconds rather than the 20 to 30 minutes typically required with a hammer and chisel. It handles nuts from 3-3/4 inches to 4-1/4 inches across the flats. Maintenance professionals, pipefitters, millwrights, and industrial mechanics use this tool in situations where conventional removal methods are impractical or unsafe.

The AS404STR is suited for heavy industrial and mechanical maintenance applications where large fasteners must be removed without heat, impact, or flame. It is commonly used in plant maintenance, petrochemical facilities, shipyards, and heavy equipment service environments. The compact profile allows use in confined or hard-to-reach spaces where swing room for a hammer is limited. Optional adapters extend capacity up to 6-1/2 inches, making the tool adaptable to a wider range of fastener sizes beyond the standard range.

Installation Notes

This tool is typically operated by licensed millwrights, pipefitters, or qualified maintenance mechanics. Before use, relieve any system pressure or mechanical load on the fastener being removed. Verify the cutting chisel is properly calibrated and seated against the nut flat before applying hydraulic pressure. Follow the manufacturer's operating instructions and relevant facility safety protocols when working in classified or restricted areas.
