Material 65Mn (spring steel), heat treatment, hardness HRC44 ~ 51HRC, by surface oxidation. Washer (spring) washers, retainer is resilient pad or card
In short, bolts, washers, although very small, inconspicuous basic mechanical parts, in fact, inside the mechanical problems, material problems, and even a lot of mechanical principle problem at all, critical time can not be a little sloppy.
Such fastening member such as a bridge to see the site, designed to tighten these places a number of factors in addition to the above, there is more attention, including the installation of fastening installation technology, maintenance, preservation, and other aspects to consider replacing damaged.

3.Application
Flat pad acts 2: one is the screw is too long: There is a screw or deduction is half plus flat pad cap on it with full, the screw the other is where the hole is too big plus flat pad will not take down the drain
4.Advantage
1. Under Under normal circumstances, the load is relatively small, and not subjected to vibration load situation can only pad.
2. Under the load is relatively large, and withstand vibration load case, you must use flat washers, spring washers combinations.
3. The spring washer is not substantially alone, they are used in combination.
