Product description

Single-sided, mechanical nut splitters are used for splitting seized, rusted or over-turned nuts up to a tensile strength of 800 N/mm2. In this splitting process, the threaded end remains undamaged. When tightening the spindle, the sharp cut of the chisel, sharpened by a facet, penetrates deep into the nut until it is split. In restricted environmental conditions, when only limited space is available around the nut, the single-sided nut splitter is exactly the right choice.

Application

For loosening stuck, rusted or crazy nuts with a tensile strength of up to 800 N/mm².
