螺絲種類2<一>頭部剖溝,螺絲刀咀型:
a.Slotted:一字
螺絲種類2
螺絲種類2(5張)
b.Phillips:十字
c.Phil-Slot:一字/十字
d.HexScoket:內六角
e.OneWay:單向(只可鎖入,不可退出)

d.Pan:圓扁頭/盤頭
e.Truss:大圓扁頭

<四>螺紋規格:
a.公制螺絲
螺絲種類螺絲種類1(5張)
Ex:M6x8-PPB
M6x1機械牙螺絲,8mm長,十字溝槽,圓扁頭,鍍黑.
b.美制螺絲
美規螺絲一般以番號標示,
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
***牙數為每英寸牙的數量,長度須經過換算才是公制mm尺寸,1"(英寸)=25.4mm(毫米).***
c.英制螺絲:
標示皆將分母為8,再直接稱分子之番號.
Ex:1/8x0.50-PPB:1分牙螺絲釘x0.50”長,PPB
Ex:5/16x0.50-PPB=2.5/8x0.50-PPB:2分半牙螺絲釘x0.50”長,PPB
Ex:5/32x0.50-PPB=1.25/8x0.50-PPB:1分2厘半螺絲釘x0.50”長,PPB
Ex:1/4x0.50-PPB=2/8x0.50-PPB:2分牙螺絲釘x0.50”長,PPB
注:有時會標示粗牙或細牙
UNF:細牙:電子業較常用
UNC:粗牙:重機械結構較常用
Ex:3/8x0.50UNF-PPB:3分細牙螺絲釘x0.50”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換算才是公制mm尺寸,1"(英寸)=25.4mm(毫米).***
規格表
那么如果有一個螺絲規格表，把螺絲螺紋牙距，螺絲種類，螺絲各方面基本信息都用一個圖表來表示，清楚，明了，簡單易懂。那么使用起來就方便多了。下面把螺絲規格表，把螺絲螺紋牙距規格表顯上，供大家方便使用，查詢。
