1、國家標(biāo)準(zhǔn)螺絲規(guī)格表，螺絲牙距規(guī)格表我們螺絲行業(yè)的螺絲生產(chǎn)廠家，在生產(chǎn)制造當(dāng)中，銷售過程當(dāng)中，服務(wù)客戶過程當(dāng)中，遇到客戶問，什么樣的螺絲規(guī)格是什么，它們的螺紋牙距是多少？那么如果有一個螺絲規(guī)格表，把螺絲螺紋牙距，螺絲種類，螺絲各方面基本信息都用一個圖表來表示，清楚，明了，簡單易懂。那么使用起來就方便多了。下面深圳市創(chuàng)固螺絲朱經(jīng)理，把螺絲規(guī)格表，把螺絲螺紋牙距規(guī)格表顯上，供大家方便使用，查詢。螺絲規(guī)格表a.
