On several types of lock washers, stamping can also be used to form bent teeth or tabs. Lock washers are designed to keep a threaded fastener from loosening by incorporating teeth or tabs that increase friction and locking. Metal stamping is a time-consuming and multi-step process. Washers, a steel stamp set, a hammer, and a permanent Sharpie marker are all required. You can use any size washer you want, but for the small ones, I used 1/4 inch washers and for the large ones, I used 5/8 inch washers.
Flanging, piercing, blanking, coining, and shearing are some of the operations used in die stamping. Die stamping is a technique for shaping and cutting the metal into a specific shape. Die stamping can be done in three ways: line, transfer, or progressive, with progressive being the most common.
Because the tapping process takes so much time and effort, ESI came up with a better solution. We partnered with REMINC's screw and bolt family to eliminate pre-tap work and significantly reduce the remaining 85 percent of the cost. You can avoid drilling by eliminating tapping, and you'll get stronger fastening and higher-quality assemblies as a result.
