style="text-indent:25px">螺栓在日常生活當(dāng)中和工業(yè)生產(chǎn)制造當(dāng)中，是少不了的，螺栓也被稱為工業(yè)之米?？梢娐菟ǖ倪\(yùn)用之普遍。螺栓的運(yùn)用范圍有：電子產(chǎn)品，機(jī)械產(chǎn)品，數(shù)碼產(chǎn)品，電力設(shè)備，機(jī)電機(jī)械產(chǎn)品。船舶，車輛，水利工程，甚至化學(xué)實驗上也有用到螺栓。反正是超多地方都有用到螺栓的。特如數(shù)碼產(chǎn)品上面用到的精密螺栓。受力方式：普通的和有鉸制孔用的。普通的主要承載軸向的受力，也可以承載要求不高的橫向受力。鉸制孔用的螺栓要和孔的尺寸配合，用在受橫向力時。</p><p style="text-indent:25px">M表示“公制，米制”螺紋。完整的螺紋標(biāo)記是由：螺紋特征代號＋尺寸代號＋公差帶代號＋及其他信息組成＋標(biāo)準(zhǔn)代號（如：對國產(chǎn)螺絲加國標(biāo)代號）1、螺紋的特征代號用字母“M”2、尺寸代號單線螺紋的尺寸代號為“公稱直徑×螺矩”。對粗牙螺紋可以省略標(biāo)注其螺矩項。多線螺紋的尺寸代號為“公稱直徑×Ph導(dǎo)程P螺矩”。3、公差帶代號由數(shù)字加字母表示（內(nèi)螺紋用大寫字母，外螺紋用小寫字母），如7H、6g等，應(yīng)特別指出，7H，6g等表示螺紋公差，而H7，g6表示圓柱體公差代號。4、旋合長度規(guī)定為短（用S表示）、中（用N表示）、長（用L表示）三種。一般情況下，不標(biāo)注螺紋旋合長度，其螺紋公差帶按中等旋合長度（N）確定。必要時，可加注旋合長度代號S或L，如“M20-5g6g－L”。特殊需要時，可注明旋合長度的數(shù)值，如“M20-5g6g－30”。5、左旋螺紋應(yīng)在旋合長度之后標(biāo)注“LH”。旋合長度代號與旋向代號間用“－”分開，右旋螺紋省略不注。螺栓連接是屬于可拆卸連接。</p><div

螺絲螺母是很多機(jī)械產(chǎn)品中較為基本的零件?，F(xiàn)在外六角螺栓在市場上發(fā)展的也越來越快。那么六角螺栓在自行車上主要起到了什么作用呢?外六角螺絲常用在機(jī)械中,主要有便于緊固,拆卸,不易滑角等優(yōu)勢。外六角螺絲分為：右螺紋，左螺紋。順時針轉(zhuǎn)的，就是右螺紋，反之就是左螺紋。目前自行車上面的逆牙，只有五通BB與踏板，在這兩個地方會用到反牙。其它的都是正牙。外六角螺絲外徑的大小以牙峰作為圓周外徑，所測量出的直徑大小。外六角螺絲在單車上的材質(zhì)，常見的有鋼，鋁合金與鈦合金這種三種質(zhì)，目前也有自行車廠商用碳纖維的內(nèi)六角螺絲。而跟鋁合金與鈦合金外六角螺絲相比較，鋼類外六角螺絲比較能鎖得緊物體。沉頭螺栓安裝后表面不能有凸起的地方。u型螺絲價格</p><p
