31、: 公制机械螺丝: Metric Ex: M3 x 6 P P B : M3 机械螺丝, 6mm 长, 十字, 圆扁头, 镀黑.Finish Code: 外观处理规格。Head Code: 头部外型。Thread Code螺丝型号 Drive Code: 头部剖沟,特征型号 Length Code: 螺丝长度 (mm) A-1: Thread Code: 螺丝型号公制螺丝直接以螺丝外径标示螺丝型号, 如M3 即螺丝外径为3.00mm.; M4 即螺丝外径为4.00mm. Metric Thread Size x Pitch: Note: 公制螺丝于螺丝型号后方,有时会注明螺丝牙距.

32、如M3x0.5 , M4x0.70, M5x0.8 , M6x1. 但因为标准规范, 通常不提. A-2: Length Code: 螺丝长度:公制螺丝, 直接标示螺丝长度, 单位为mm. 螺丝之总长度标示, 只计算头部以下之长度, 不含头部高度. 但平头螺丝例外, 其螺丝之总长度标示含头部高度. A-3: Drive Code/ 头部剖沟,特征. 一般常用规格如下: a. Slotted: 一字 ( Minus ) b. Phillips: 十字 ( Plus ) c. Phil-Slot: 一字/十字 d. Hex Scoket: 内六角 e. One Way: 单向

33、(只可锁入,不可退出) A-4: Head Code/ 头部外型. 一般常用规格如下: a. Flat: 平头 (锁入后,顶部与工作件齐平) b. Oval: 色拉头 c. Round: 圆头 d. Pan: 圆扁头 e. Truss: 大圆扁头 f. Hex : 六角头. A-5: Finish Code/ 外观处理. 一般常用规格如下: a. Z: Zine-Plated: 镀锌 b. Ni: Ni-Plated: 镀镍 c. Tin-Plated: 镀锡 d. Zine Plated / Green Iridite: 镀锌绿膜处理. e. Radiant Plated

34、: 镀五彩 f. Passivate: 抗氧化处理. g. Alodial Finish: 无外观处理 公制自攻螺丝 :于品名后方直接标示 Tapping Type. Ex: M3 x 6 PPB, Tapping Type: M3 自攻螺丝, 6mm 长, 十字, 圆扁头, 镀黑. 一般以产品别或标示, 再判断为Sheet Metal 或塑料部品使用.B: 美规螺丝.a.一般以番号标示, 如 #2-56, #4-40, #6-32, #8-32, #10-24etc. b.或以英制外径表示, 如0.086-56, 0.112-40 , 0.138-32 , 0.164-3

35、2 , 0.190-24etc. Ex: 632 8 P P B: Finish Code: 外观处理规格 Head Code: 头部外型 Drive Code: 头部剖沟,特征型号 Length Code: 螺丝长度 Thread Code: 螺丝型号B-1: Thread Code: 螺丝型号 一般常用规格如下: a. #2-56 (0.086-56): 2 番 56 牙 b #4-40 (0.112-40) : 4 番40 牙 c. #6-32 (0.138-32) : 6 番32 牙 d. #8-32 (0.164-32) : 8 番 32 牙 e. #10-24 (0.19

36、0-24): 10 番 24 牙 B-2: Length Code: 螺丝长度 美规螺丝长度须经换算, 才是公制mm 尺寸. 换算公式: (Length Code / 32) x 25.40 = 公制长度mm B-3, B-4,B-5 : 标示方式与公制相同.C: 英制螺丝: C-1: Thread Code: 标示皆将分母为8, 再直接称分子之番号. Ex: 1/8 x 0.50 PPB: 1 分牙螺丝 x 0.50” 长, PPB Ex: 5/16 x 0.50 PPB = 2.5/8 x 0.50-PPB : 2 分半牙螺丝 x 0.50” 长, PPB Ex: 5/32 x 0.50 PPB =1.25/8 x 0.
