Trendy: Outdoor belt buckle that is used with a bag with a hook. A plastic strap adjuster (tri-bar adjuster) is preferred not to release one side of a PP belt from the buckle. Just put a PP belt through ditches of the adjuster from both sides. Note that some type of outdoor belt buckles is patented on Austria, U.S.A. (US8561268B2), Europe, Spain, and Canada. In past days, these goods could be found in magazines in street stores, and these are now found on scattered pages online.

My clipper head was assembled by 2.6mm flat head screw, but the diameter of the head is the same as the head of M3 screw. The head is needed to be fit with a spot hole on the iron blade. Is it inch screw? Anyway, I lost the screw, and fixed by M3 flat head one (Unichrome M3 * 10mm and 0.5mm pitch). It was hard to expand the threaded hole on the plastic base using a 2.5mm pin vise. Heads of several screws are broken in the process. I didn't bet on a self-tapping screw.
