초록
In this paper, we analyze the standards of the bolts for maintaining the products. The maintainer don't know the detail information of bolts by seeing the shape of bolts when they repair the products. So they waste much time and cost. To solve the these problem, we propose the new systematical discrimination of bolts. To propose the discrimination code, we divide the shapes of the bolts into four classes(head, internal drive, shank and end). User can fine preferentially similar standards by just the shapes of bolts under the this discrimination code. And, User can find the standards of bolts that they want by using the additional information such as measurements. We will reduce the cost and time for the maintaining the products by using the proposed discrimination code.
