螺絲規(guī)格表 - 衡量螺絲是否標(biāo)準(zhǔn)的數(shù)據(jù)表
螺絲規(guī)格表是衡量螺絲是否標(biāo)準(zhǔn)的數(shù)據(jù)表。在設(shè)計過程當(dāng)中，生產(chǎn)制造當(dāng)中，銷售過程當(dāng)中，服務(wù)客戶過程當(dāng)中能得到廣泛的應(yīng)用。
常見螺絲
<一>頭部剖溝,螺絲刀咀型:
a.?Slotted:?一字
b.?Phillips:?十字
c.?Phil-Slot:?一字/十字
d.?Hex?Socket:?內(nèi)六角
e.?One?Way:?單向 - 只可鎖入,不可退出
<二>螺絲頭頭型:
a.?Flat:?平頭 - 鎖入后,頂部與工作件齊平
b.?Oval:?色拉頭
c.?Round:?圓頭
d.?Pan:?圓扁頭/盤頭
e.?Truss:?大圓扁頭
f.?Hex?:?六角頭
<三>?外觀表面處理:
a.?Z:?Zine-Plated:?鍍鋅
b.?Ni:?Ni-Plated:?鍍鎳
c.?Tin-Plated:?鍍錫
d.?Zine?Plated?/?Green?Iridite:?鍍鋅綠膜處理.
e.?Radiant?Plated:?鍍五彩
f.?Passivate:?抗氧化處理
g.?Alodial?Finish:?無外觀處理
<四>螺紋規(guī)格:
a.?公制螺絲
Ex:?M6?x?8?–?PPB
M6x1機(jī)械牙螺絲,?8mm長,?十字溝槽,?圓扁頭,?鍍黑.
b.?美制螺絲
美規(guī)螺絲一般以番號標(biāo)示,
如#2-56,?#4-40,?#6-32,?#8-32,?#10-24…etc.
Ex:?#2-56? - 0.086-56:?2?番56?牙
Ex:?#4-40? - 0.112-40?:?4?番40?牙
Ex:?#6-32? - 0.138-32?:?6?番32?牙
Ex:?#8-32? - 0.164-32?:?8?番32?牙
Ex:?#10-24? - 0.190-24:?10?番24?牙
牙數(shù)為每英寸牙的數(shù)量,長度須經(jīng)過換算才是公制mm?尺寸,1" - 英寸=25.4mm - 毫米.
c.?英制螺絲:
標(biāo)示皆將分母為8,?再直接稱分子之番號.
Ex:?1/8?x?0.50?–?PPB?:?1?分牙螺絲釘x?0.50”?長,?PPB
Ex:?5/16?x?0.50-?PPB?=?2.5/8?x?0.50?–?PPB?:?2?分半牙螺絲釘x?0.50”?長,?PPB
Ex:?5/32?x?0.50-?PPB?=1.25/8?x?0.50?–?PPB?:?1?分2?厘半螺絲釘x?0.50”?長,?PPB
Ex:?1/4?x?0.50-?PPB=?2/8?x?0.50?–?PPB?:?2分牙螺絲釘x?0.50”?長,?PPB
注:?有時會標(biāo)示粗牙或細(xì)牙
UNF:?細(xì)牙:電子業(yè)較常用
UNC:粗牙:?重機(jī)械結(jié)構(gòu)較常用
Ex:?3/8?x?0.50?UNF?-PPB?:?3分細(xì)牙螺絲釘x?0.50”?長,?PPB.
或以英制外徑表示,
如0.086-56,?0.112-40?,?0.138-32?,?0.164-32?,?0.190-24…etc.
Ex:?632?–?8?–?PPB.
英制螺絲外徑和長度長度須經(jīng)換算才是公制mm?尺寸,1" - 英寸=25.4mm - 毫米.
