M4*7 Galvanized Round Head Welding Nut A3 Steel
There are two types of cap nuts according to the production process. One is the combined type, which is welded. The semicircular part on the upper part is post-welded, mainly the small cold-headed cap; the other is the integrated type, because the production process is difficult. It is large and has many materials, so the price is slightly higher than that of the split body, but the appearance is more beautiful.
