Description
Overview:
This Metric Nylon Insert Locking Nut (Type 'P'), size M12, is a hexagonal steel nut with a captive nylon collar that provides prevailing torque to resist loosening. The zinc plating offers a bright, silver finish and added protection against corrosion, making it suitable for use indoors and outdoors. Designed to DIN 982 standards, it delivers consistent performance under vibration and shock. Commonly used with bolts, set screws, or threaded rod on machinery, vehicles, plant, construction fixings, and garden equipment, it helps maintain secure joints where reliability matters. Supplied as a pack of 100 for workshop stock or site work, these nuts fit standard M12 metric threads and can be installed with a standard 19 mm spanner or socket, tightening to the equipment manufacturer's specified torque.
