This set includes 80 expansion screw petal nuts, with specifications of M4-20, M4-25, M5-25 and M6-25. It meets various usage needs in your daily life and ensures an adequate number of replacements. The metal petal nuts are treated with galvanization on their surfaces, presenting a silver color and effectively preventing corrosion and rusting
When using the expansion screw petal nuts, you can operate it easily with two wrenches or pliers. One wrench is used to fix the nut to prevent it from rotating in the hole, and the other is used to tighten the screw. When you tighten the screw, the nut will gradually contract and firmly fix in place, avoiding over-tightening which could damage the threads
Similar to ordinary screws and nuts, you simply insert the screw into the component to be fixed, then install the nut and screw it into the screw. As you rotate it, the nut will gradually open, thereby increasing the fixation range. It is very convenient
These expansion screw petal nuts are made of high-quality carbon steel, which are sturdy and durable, resistant to rust and corrosion, and have a long service life. The expansion head of the nut is larger, enabling it to firmly fix on the sheet material and possess good load-bearing capacity
This extension screw kit is highly suitable for installing thin items. The petal nuts can be used with various materials, including plastic, composite wood, hollow walls and iron sheets, and is an indispensable multi-functional tool for any DIY or construction project
