十字槽盤頭自攻螺釘最小公稱直徑多少?附帶國標號!

最小公稱直徑2.2，標準(zhun)號：GB/T 845-1985 按照(zhao)以下幾個尺寸標準(zhun)。1、GB/T845-1985十(shi)字槽盤頭自攻螺釘，滲碳鋼鍍鋅鈍(dun)化。2、GB/T2670.1-2004內化六角花(hua)形盤頭自攻螺絲(si)釘。3、GB/T5282-1985開槽盤頭自攻螺絲(si)釘，滲碳鋼鍍鋅鈍(dun)化。

十字槽盤頭自攻螺釘(GB/T845-1985-ST4.2X16-C-H) 直徑多少

正巧在查表：公(gong)稱直(zhi)徑4.2 P：1.4 d1：4.04~~4.22 d2：2.95~~3.1 可以查詢GB/T 5280-2002

GB/T845-1985自攻螺絲ST3.5*10代表是不銹鋼螺絲還是普通螺絲。_百度知

這個(ge)是(shi)“十字槽盤頭(tou)自攻螺釘(ding)”，規格(ge)ST3.5，公稱長度10，表面是(shi)鍍鋅鈍化。不(bu)是(shi)不(bu)銹(xiu)鋼。

螺釘GB845-85,ST2.9*8的是標準的嗎

是國(guo)際標(biao)準，GB845-85是國(guo)標(biao)編號，ST2.9*8是螺(luo)釘(ding)規格。螺(luo)釘(ding)GB845-85，ST2.9*8代表(biao)(biao)(biao)的(de)(de)(de)意義：螺(luo)紋(wen)(wen)規格為(wei)2.9mm,長度(du)(du)8mm的(de)(de)(de)盤頭(tou)十字槽(cao)自(zi)(zi)攻螺(luo)釘(ding)。公制(zhi)(zhi)螺(luo)紋(wen)(wen)是以MM（毫米(mi)）為(wei)單(dan)位，它的(de)(de)(de)牙尖角為(wei)60度(du)(du)。美制(zhi)(zhi)螺(luo)紋(wen)(wen)和(he)英制(zhi)(zhi)螺(luo)紋(wen)(wen)都是以英寸(cun)為(wei)單(dan)位的(de)(de)(de)。美制(zhi)(zhi)螺(luo)紋(wen)(wen)的(de)(de)(de)牙尖角也是60度(du)(du)，而英制(zhi)(zhi)螺(luo)紋(wen)(wen)的(de)(de)(de)牙尖角為(wei)55度(du)(du)。由于 自(zi)(zi)攻螺(luo)絲規格尺寸(cun)表(biao)(biao)(biao) 1. 規格：1.2mm 描述(shu)：GB / T845-1985 十字槽(cao)盤頭(tou)自(zi)(zi)攻螺(luo)釘(ding)，采用滲(shen)碳鋼材質，表(biao)(biao)(biao)面鍍(du)鋅并鈍(dun)化處(chu)理(li)。2. 規格：1.4mm 描述(shu)：GB / T846-1985 十字槽(cao)沉頭(tou)自(zi)(zi)攻螺(luo)釘(ding)，使用滲(shen)碳鋼材質，表(biao)(biao)(biao)面鍍(du)鋅并鈍(dun)化處(chu)理(li)。3. 規格：1.6mm 描述(shu)：GB / T2670.1-2004 內六角花形盤頭(tou)自(zi)(zi)攻螺(luo)釘(ding)。4

以上就是小編對于十字(zi)槽盤(pan)頭自攻螺釘F型(xing) GB/YB 845 問題和相關問題的解答了(le)，希望對你(ni)有用(yong)。
