Wera 3869/4 Stainless Steel Nutsetter

The Wera 3869/4 Stainless Steel Nutsetter in 13mm is the largest in the range, designed for heavier hexagon head screws and bolts commonly used in structural steelwork, mechanical assemblies, and industrial applications where stainless fixings are specified for corrosion resistance. As with the entire 3869/4 series, the stainless steel construction directly solves the extraneous rust problem — ensuring that no rust contamination is introduced to the workpiece from the tool itself. This is essential when working with high-grade stainless assemblies in demanding environments such as offshore, food processing, or pharmaceutical settings. The non-magnetic construction and integral retaining spring combine to deliver precise, controlled fastening, while the 1/4" hexagon drive ensures compatibility with Wera connecting series 4 holders and DIN ISO 1173-F 6.3 compliant equipment.
