style="text-indent:25px">螺栓市場(chǎng)競(jìng)爭(zhēng)激烈，走向品牌經(jīng)營(yíng)。近10年，我國(guó)螺栓令世人矚目的發(fā)展速度，令發(fā)達(dá)國(guó)家感到吃驚的同時(shí)，也讓他們發(fā)現(xiàn)一個(gè)新型的大市場(chǎng)，跨國(guó)公司魚(yú)貫而入。當(dāng)國(guó)內(nèi)螺栓企業(yè)忽然覺(jué)得在市場(chǎng)上生存得如此艱難時(shí)，強(qiáng)有力的競(jìng)爭(zhēng)對(duì)手已遍地開(kāi)花。當(dāng)今中國(guó)螺栓的市場(chǎng)，一些中小型螺栓企業(yè)大量制造普通標(biāo)準(zhǔn)件，并沒(méi)有真正為企業(yè)帶來(lái)高級(jí)競(jìng)爭(zhēng)力，反而受制于原材料、人力成本等條件的變化。從4.8級(jí)到6.8級(jí)低強(qiáng)度，或8.8級(jí)到12.9級(jí)**度螺栓，中國(guó)螺栓的生產(chǎn)技術(shù)水平將基本接近世界先進(jìn)水平，主要為普通標(biāo)準(zhǔn)件及低、中檔次的特種、異型螺栓，量大價(jià)廉。概括為低檔次產(chǎn)品充斥主導(dǎo)市場(chǎng)，高精度、**度螺栓有一小部分仍需進(jìn)口，產(chǎn)品進(jìn)口單價(jià)與出口單價(jià)的比值差距約6倍以上。</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(hào)＋尺寸代號(hào)＋公差帶代號(hào)＋及其他信息組成＋標(biāo)準(zhǔn)代號(hào)（如：對(duì)國(guó)產(chǎn)螺絲加國(guó)標(biāo)代號(hào)）1、螺紋的特征代號(hào)用字母“M”2、尺寸代號(hào)單線(xiàn)螺紋的尺寸代號(hào)為“公稱(chēng)直徑×螺矩”。對(duì)粗牙螺紋可以省略標(biāo)注其螺矩項(xiàng)。多線(xiàn)螺紋的尺寸代號(hào)為“公稱(chēng)直徑×Ph導(dǎo)程P螺矩”。3、公差帶代號(hào)由數(shù)字加字母表示（內(nèi)螺紋用大寫(xiě)字母，外螺紋用小寫(xiě)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(hào)。4、旋合長(zhǎng)度規(guī)定為短（用S表示）、中（用N表示）、長(zhǎng)（用L表示）三種。一般情況下，不標(biāo)注螺紋旋合長(zhǎng)度，其螺紋公差帶按中等旋合長(zhǎng)度（N）確定。必要時(shí)，可加注旋合長(zhǎng)度代號(hào)S或L，如“M20-5g6g－L”。特殊需要時(shí)，可注明旋合長(zhǎng)度的數(shù)值，如“M20-5g6g－30”。5、左旋螺紋應(yīng)在旋合長(zhǎng)度之后標(biāo)注“LH”。旋合長(zhǎng)度代號(hào)與旋向代號(hào)間用“－”分開(kāi)，右旋螺紋省略不注。細(xì)腰螺栓螺栓有利于受變力的聯(lián)結(jié)。</p><div
