style="text-indent:25px">強度等級所謂8.8級和10.9級是指螺母的抗剪切應力等級為8.8GPa和10.9Gpa8.8公稱抗拉強度800N/MM2公稱屈服強度640N/MM2一般的螺母是用"X.Y"表示強度的，X*100=此螺母的抗拉強度，X*100*（Y/10）=此螺母的屈服強度（因為按標識規(guī)定：屈服強度/抗拉強度=Y/10）如4.8級則此螺母的抗拉強度為：400MPa屈服強度為：400*8/10=320MPa。不銹鋼螺母通常標為A4-70，A2-70的樣子，不銹鋼螺母的等級分為45、50、60、70、80，材料主要分奧氏體A1、A2、A4，馬氏體和鐵素體C1、C2、C4，其表示方法例如A2-70，“--”前后分別表示螺母材料和強度等級：“A2-70”是不銹鋼螺母、螺釘、螺柱和螺母的性能標記，“-”前的“A2”表示的是材料組別，即奧氏體鋼第二組A2，“-”后的數(shù)字部分“70”表示產品的性能等級，其數(shù)字為公稱抗拉強度的1/10，即此產品的性能抗拉強度為700N/mm2。南京螺母求購螺母是配合螺栓或螺釘連接用的一類緊固件。</p><div

style="text-indent:25px">法蘭螺母：法蘭螺母又叫法蘭帶齒六角螺母，就是比六角螺母多了一面圓形法蘭帶齒花紋，實際使用過程更牢固，有防松的效果，因為裙邊相當于墊片，墊片和螺母是一體式的，而且在下面有防滑的齒紋，這樣增大了螺母與工件的表面積接觸，相比普通螺母加墊圈的組合，更加牢固和拉力更**蘭面螺母法蘭面有溝槽，不但增大接觸面積，還有防止松動的效果。法蘭螺母根據(jù)外形和規(guī)格分類如下：德標（DIN6923）,尼龍法蘭螺母（DIN6926）,美制法蘭螺母（IFI145）。法蘭螺母按材質分有碳鋼和不銹鋼兩種,不銹鋼分為SUS304和SUS316兩種;碳鋼根據(jù)表面處理要求可分為藍白鋅，彩鋅，黒鋅等。</p><p style="text-indent:25px">摩擦防松：這是應用較廣的一種防松方式，這種方式在鎖緊螺母副之間產生一不隨外力變化的正壓力，以產生一能夠阻止鎖緊螺母副相對轉動的摩擦力。這種正壓力可經過軸向或同時兩向壓緊鎖緊螺母副來完成。如采用彈性墊圈、雙螺母、自鎖螺母和嵌件鎖緊螺母等。構造防松是應用鎖緊螺母副本身構造，即唐氏鎖緊螺母防松方式。沖邊法防松：螺母擰緊后在螺紋末端沖點破壞螺紋；粘合防松通常采用厭氧膠粘結劑涂于螺紋旋合表面，擰緊防松螺母后粘結劑能夠自行固化，防松效果良好。這種方式的缺點是栓桿只能使用一次，且拆卸十分困難，必須破壞螺栓副方可拆。不常見螺母螺母從頭部形狀大致可分為：內六角，外六角，十字，一字，平頭，沉頭，內三角，外三角，米字形。</p><div

style="text-indent:25px">法蘭螺母(GB6177/DIN6923)和一般的六角螺母尺寸與螺紋規(guī)格基本相同，只不過比六角螺母相比，它是墊片和螺母是一體式的，而且在下面有防滑的齒紋，這樣增大了螺母與工件的表面積接觸，相比普通螺母加墊圈的組合，更加牢固和拉力更**蘭面螺母與連接件的表面接觸面積大，這就決定了它的使用情況，當螺栓螺母連接的兩部件為了連接的方便性，通常會將一個部件的螺栓孔加工非常大，這樣兩部件找正時會非常方便，2個孔不用對的很準確就可以實現(xiàn)螺栓的連接，螺栓孔加大，勢必會導致普通螺母與被連接件的接觸面積減小，使用這種法蘭面螺母就可以避免這種情況。法蘭面螺母法蘭面有溝槽，不但增大接觸面積，還有防止松動的效果，在轉動機構上常見。法蘭螺母面本身就具有平墊和彈墊的防滑和止動的作用，所以裝配的時候不需要再加上平墊和彈墊了，這樣反而會事得其反。南京螺母求購</p><p
