（1）高強螺栓：強螺栓，使回用日益普遍，主要用答在一些比如戶外工程，風電或者具有能動性的機械上，抗拉強度比較大，高強螺栓一般用于長久連接。 </p> <p> （2）普通螺栓，高用在一些小型機械，比如渦輪機上就可以，主要是看應(yīng)用環(huán)境和運作方式。 </p> <p> 2，高強螺栓和普通螺栓常用等級： </p> <p> （1）常用8.8s和10.9s兩個強度等級，其中10.9級居多。 </p> <p> （2）普通螺栓強度等級要低，一般為4.4級、4.8級、5.6級和8.8級。 </p> <p> <br /> </p><p> 要做一系列的試驗才能確定螺栓性能等級，沒有儀器做出各類數(shù)值，怎么確認呢！直觀就是外表上專有8.8字樣或4.8字樣，沒有屬則默認為4.8級。再者就是檢驗報告了，如果是正規(guī)廠生產(chǎn)的螺栓，則可依檢驗報告確認等級。 </p> <p> 普通4.8其實基本不用驗證等級與性能，只要外觀與國標尺寸一致就沒問題 </p> <p> 高強8.8或10.9只有靠廠家提供的質(zhì)量檢驗報告來判斷，不過呢，如果你買到假貨，那么檢驗報告也就是偽造的了。也不可信了。 </p> <p>

1、螺栓材質(zhì)公稱抗拉強度達400MPa級； 2、螺栓材質(zhì)的屈強比值為0.6； 3、螺栓材質(zhì)的公稱屈服強度達400×0.6=240MPa級性能等級10.9級高強度螺栓，其材料經(jīng)過熱處理后，能達到： 1、螺栓材質(zhì)公稱抗拉強度達1000MPa級； 2、螺栓材質(zhì)的屈強比值為0.9； 3、螺栓材質(zhì)的公稱屈服強度達1000×0.9=900MPa級螺栓性能等級的含義是國際通用的標準，相同性能等級的螺栓，不管其材料和產(chǎn)地的區(qū)別，其性能是相同的，設(shè)計上只選用性能等級即可。強度等級所謂8.8級和10.9級是指螺栓的抗剪切應(yīng)力等級為8.8GPa和10.9GPa 10.9s的s 表示鋼結(jié)構(gòu) </p> <p> <br />

螺栓按頭部形狀分：有六角頭的，圓頭的，方形頭的，沉頭的等等。其中六角頭是常用的，沉頭用在要求連接的地方。 </p> <p> <br /> </p> <p> 螺栓按螺紋的牙型分為粗牙和細牙兩類，粗牙型在螺栓的標志中不顯示。螺栓按照性能等級分為3.6、4.8、5.6、6.8、8.8、9.8、10.9、12.9八個等級。 </p> <p> <br /> </p> <p> 其中8.8級以上(含8.8級)螺栓材質(zhì)為低碳合金鋼或中碳鋼并經(jīng)熱處理(淬火+回火)，通稱高強度螺栓，8.8級以下(不含8.8級)通稱普通螺栓。 </p> <p> <br /> </p> <p> 普通螺栓按照制作精度可分為A、B、C三個等級，A、B級為精制螺栓，C級為粗制螺栓。對于鋼結(jié)構(gòu)用連接螺栓，除特別注明外，一般為普通粗制C級螺栓。 </p> <p>
