About this item
- You will get 12 Pcs of Insert Reducing Nuts, Female Thread Size: M2.5 x 0.45mm; Male Thread Size: M4 x 0.7mm; Length: 5mm/0.2 Inch;
- Hard and Wear-Resistant: These reducing nuts are made from good quality 316 stainless steel, which offers superior rust and corrosion resistance compared to 304 stainless steel. They also exhibit low magnetism, high hardness, and excellent heat resistance. They maintain excellent mechanical properties even under high-intensity and humid conditions, resist rust or oxidation, and maintaining a stable structure for long-term use.
- Stable thread connection: These thread-reducing nuts have a smooth burr-free surface, deep and clear threads, and uniform force, which significantly enhances the firmness and stability of the connection between the nut and other fasteners.
- Easy Installation: To facilitate installation and removal, each nut has a slot at the top for accommodating a flat-head screwdriver, making it easier to screw them in or out. (This nut does not have self-tapping capability and needs to be tapped in advance.)
- Application: Repair insert nuts are essential components in industrial fastening systems, typically used in conjunction with screws or bolts. They are an effective solution for repairing damaged or incorrectly threaded holes. These versatile repair nuts are widely used in various industries, including aviation, automotive, electronics, communications, computers, lighting, mechanical equipment, and radiators, among others.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
