Kit di 100 inserti filettati in ottone zigrinato, adatti per parti in plastica e parti per stampanti 3D, M4 x 6 mm

Durable Material: These insert nuts are made of high-quality brass, offering high strength, high hardness, chemical resistance, and wear resistance, making them widely applicable across various fields. Superior Craftsmanship: The knurled nuts with internal threads have a smooth, burr-free surface. The threads are deep, clear, and evenly distributed, providing a non-slip grip and preventing damage to other components. Secure Grip: The knurled pattern on the outer side of the threaded nuts not only enhances their appearance but also increases friction between the nut and your hand, making rotation easier. Versatile Applications: These nuts are commonly used in die casting and fastening, and are widely used in the communications, electronics, electrical, automotive, construction, and shipbuilding industries. Package Includes: 100 high-quality knurled nuts.
