Sealey 390 Piece Serrated Flange Nut Assortment Metric

The Sealey 390 Piece Serrated Flange Nut Assortment is a comprehensive metric fastener collection designed for professional tradespeople and workshops requiring convenient access to commonly used sizes. This DIN 6923 compliant assortment provides reliable fastening solutions across automotive, machinery, and general engineering applications.

This makes them particularly valuable for mechanics, machine maintenance engineers, and fabricators working on equipment subject to movement or operational stress. The assortment is supplied in a partitioned storage box that keeps each size organised and readily accessible, reducing time spent searching for the correct fastener during repairs or assembly work. With 390 pieces covering five essential metric sizes from M5 through to M12, this collection ensures workshops maintain adequate stock of these specialist nuts for both planned maintenance and emergency repairs.
