1. Markings: Pamabhaudhi ane hexagonal uye screws (thread diameter>5mm), ma marks anofanirwa kuitwa pamusoro pemusoro uchishandisa mabhii akasimudzwa kana akadzokororwa, kana padivi pemusoro uchishandisa mabhii akadzokororwa.Izvi zvinosanganisira mamakisi ekuita uye mamakisi emugadziri.Pakabhoni simbi: Kodhi yekumaka giredhi resimba inoumbwa nemaseti maviri enhamba dzakapatsanurwa ne“·”.Zvinorehwa nechikamu chenhamba pamberi pa“·” mukodhi yekumaka zvinoratidza kusimba kwezita.Semuenzaniso, "4" mugiredhi 4.8 inoratidza simba rezita re400N/mm2, kana 1/100 yeiyo.Zvinorehwa nechikamu chenhamba mushure me“·” mukodhi yekumaka zvinoratidza goho-ku-tensile reshiyo, inova reshiyo yezita regoho rezita kana simba regoho rezita kusimba rezita.Semuenzaniso, iyo goho poindi yechigadzirwa chegiredhi 4.8 i320N/mm2.Stainless simbi chigadzirwa chesimba giredhi mamaki anoumbwa nezvikamu zviviri zvakapatsanurwa ne "-".Chiratidzo chiri pamberi pe "-" mukodhi yekumaka inoratidza zvinhu, zvakadai seA2, A4, nezvimwewo. Chiratidzo mushure me "-" chinoratidza simba, seA2-70.

2).Giredhi: Yekabhoni simbi, metric bolt mechanical performance mamakisi anogona kukamurwa kuita gumi ekuita mamakisi: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, uye 12.9.Simbi isina tsvina yakakamurwa kuva mapoka matatu: 60, 70, 80 (austenitic);50, 70, 80, 110 (martensitic);45, 60 (ferritic).

7. Surface Treatment

Kurapa kwepamusoro kunonyanya kuwedzera kusadzivirirwa kwecorrosion, uye vamwe vanofungawo nezveruvara, saka iri kunyanya kune zvigadzirwa zvekabhoni simbi, izvo zvinowanzoda kurapwa kwepamusoro.Mishonga yakajairika pamusoro pepamusoro inosanganisira kusviba, kuvheneka, kuputika kwemhangura, nickel plating, chrome plating, sirivheri plating, goridhe plating, dacromet, hot-dip galvanizing, nezvimwewo;kune marudzi akawanda eku galvanizing, akadai seblue and white zinc, blue zinc, white zinc, yellow zinc, black zinc, green zinc, etc., uye anoiswawo mumhando dzinoenderana nemhoteredzo uye dzisiri dzezvakatipoteredza.Chikwata chega chega chine akawanda ekuputira makobvu kuti asangane neakasiyana emunyu wekupfapfaidza bvunzo zvinodiwa.

Mhedziso yeMotokari Yakajairwa Zvigadzirwa Zvigadzirwa

1).Mhedziso yeMotokari Zvikamu Zvikamu

Zvikamu zvemotokari zvakajairwa zvine akasiyana siyana uye anoshandiswa mukugadzirwa chaiko kwezvakasiyana zvikamu uye zvikamu zvemotokari, pamwe nekubatanidza uye kuungana kweakasiyana masisitimu kuti aumbe mota yese.Hunhu hwezvikamu zvakajairwa hune hunhu hwakakosha pahupamhi hwese uye kushanda kwemishini yemagetsi, uye vagadziri vemotokari vanowanzove nemaitiro ekuongorora akasimba uye zviyero zvetifiketi zvefastener masisitimu ekupa.Saizi yakakura yemusika weindasitiri yemotokari inopa yakafara nzvimbo yekusimudzira yemotokari zvakajairwa zvikamu zvigadzirwa.Zvinoenderana nenhamba, mota yakareruka kana yemutakuri inoda anenge 50kg (anenge 5,000 zvidimbu) zvezvikamu zvakajairwa, nepo yepakati kana inorema-basa rekutengesa mota inoda anenge 90kg (anenge 5,710 zvidimbu).

2).Automotive Standard Parts Numbering

Injini yega yega inogadzira injini muindasitiri yemotokari inoshandisa yakajairwa "Motokari Yedziviriro Zvikamu Zvigadzirwa Kuverengera Mitemo" (QC/T 326-2013) kugadzira zvakatemwa zvemabhizinesi akajairwa zvikamu zvekuverengera, uye zvirimo zvinoramba zvakafanana kunyangwe zvakasiyana.

Zvemotokari zvakajairwa zvikamu zvekuverengera kazhinji zvine zvikamu zvinomwe, mukurongeka:

- Chikamu 1: Zvemotokari zvakajairwa zvikamu zvekodhi kodhi;
- Chikamu 2: Yakasiyana kodhi;
- Chikamu 3: Shandura kodhi (sarudzo);
- Chikamu 4: Dimensional yakatarwa kodhi;
- Chikamu 5: Mechanical kuita kana kodhi yezvinhu;
- Chikamu 6: kodhi yekurapa kwepamusoro;
- Chikamu 7: Classification kodhi (sarudzo).

Muenzaniso: Q150B1250TF61 inomiririra bhaudhi remusoro rine hexagonal rine tambo yakatarwa yeM12, bhaudhi kureba kwe50mm, giredhi rekuita re10.9, uye isiri-electrolytic zinc plating (silver-grey) coating.Iyo nzira yekumiririra ndeiyi inotevera:
