80 Stück Spreizschrauben-blütenblattmuttern, M4-25, Blütenblattförmige Metallmuttern

【Quick Installation】This tool makes it even easier. You can use two wrenches or pliers. One is to secure the rivet nut so it won't rotate after being inserted into the hole. Screw the correct size screw into the nut. Tighten the nut with the other wrench/pliers. As you tighten the screw/bolt, the nut will crimp and hold in place. Do not overtighten, or you may strip the thread. 【Easy to Use】Just like using a regular screw and nut, screw the screw into the part you want to secure, then install the nut and tighten the nut inside the screw. As you rotate, the nut will gradually open and increase the securing range. 【Material】The petal nuts are made of high-quality carbon steel, sturdy, rust- and corrosion-resistant, and have a long service life. The larger expansion head of the nut allows for a firm hold on boards and has good load-bearing capacity. 【Multi-Purpose】These expansion screw sets are perfect for installing thin items. Petal nuts can be used on a variety of materials, including plastic, polyethylene, hollow walls, sheet metal, etc., making them a versatile addition to any DIY or construction project.
