2520不銹鋼開口銷介紹

2520不銹鋼開口銷銷售電話:13920191906

2520不銹鋼開口銷是2520不銹鋼金屬五金件的一種,俗稱2520不銹鋼彈簧銷,2520不銹鋼開口銷的作用于螺紋連接防松,把開口銷插入螺母槽與螺栓尾部孔內,并將開口銷尾部扳開,防止螺母與螺栓的相對轉動。生產的材料一般有2205不銹鋼開口銷,2507不銹鋼開口銷、321不銹鋼開口銷、2520不銹鋼開口銷、304不銹鋼開口銷,310s不銹鋼開口銷,2520不銹鋼開口銷。2520不銹鋼開口銷的材料韌性要求比較高,2520不銹鋼開口銷的每一個腳都應該能夠承受反復多次的的彎曲,而彎曲部分不發生斷裂或裂痕。彎曲方法:2520不銹鋼開口銷把不銹鋼開口銷拉開,將其任一直腳部分夾緊在檢驗模內(不應發生壓扁現象);然后將不銹鋼開口銷彎曲90°,往返一次為一次彎曲。試驗速度不應超過60次/min。檢驗模應制出半圓槽孔,其直徑即是開口銷的公稱規格。2520不銹鋼開口銷鉗口應有r=0.5mm的圓角。

螺栓類:310s不銹鋼螺栓,2520不銹鋼螺栓,310s不銹鋼螺母,2520不銹鋼螺母,加大超長外六角螺栓、外六角法蘭面螺栓、內六角圓柱頭螺栓、吊環螺栓、膨脹螺栓、沉頭內六角螺栓、盤頭內六角螺絲、馬車螺栓、雙頭螺栓、蝶型螺絲、活節螺栓、地腳螺栓、U型螺栓、四角螺栓、等
