Dacromet Hex Socket Bolts: Babban Rufin Anti-lalata Ya Haɗu da Ƙirar Ƙira

2026-07-27

Dacromet hex soket bolts suna wakiltar haɗin gwiwar fasaha mai mahimmanci guda biyu: Tsarin Dacromet babban aikin anti-lalata da silindrical soket-head (Allen) bolt geometry. Tare, suna isar da wani bayani na fastener wanda ke jure wa yanayi mara kyau yayin da yake ba da damar ingantacciyar shigarwa mai ƙarfi, yana mai da su ba makawa a cikin motoci, marine, gini, da aikace-aikacen injina masu nauyi a duk duniya.

1. Dacromet Coating Technology

Dacromet tsarin rufi ne na tushen ruwa wanda aka samo asali don carbon da bakin karfe. Ba kamar zinc mai lantarki na al'ada ba, Dacromet yana amfani da tsarin sinadarai maras chromium (ko ƙananan-chromium) wanda ke samar da shingen shinge mai yawa na tutiya da flakes na aluminum. Sakamako shine keɓantaccen ƙaƙƙarfan azurfa- launin toka wanda ya haɗu da tsaka tsaki na ado tare da aikin kariya na musamman.

Yadudduka uku suna aiki tare don samar da cikakkiyar kariya:

Zinc-aluminum flake base Layer - yana ba da kariya ta hadaya (cathodic), lalata ta fi dacewa don kare tushen karfen da ke ƙasa, yayin da flakes na aluminum yana ƙara kariya ta shinge.

Passivation tsakiyar Layer - fim ɗin chromate/silicate na inorganic wanda ke rufe tsarin ƙwanƙolin ƙarfe, tsayayya da feshin gishiri, harin sinadarai, da zafi fiye da yadda aka saba sanya zinc.

Babban rigar hatimin kwayoyin halitta (na zaɓi) - yana haɓaka aikin rigakafin juriya da juriya na yanayi, yayin da ke samar da daidaitaccen siffa mai launin azurfa da launin toka tare da ƙarancin ƙima.

2. Hex Socket Bolts

Hex soket bolts, wanda kuma aka sani da socket head screws ko Allen bolts, yana da shugaban silindiri tare da drive mai hexagonal na ciki. Wannan lissafin yana ba da damar watsa juzu'i mai girma tare da ƙaramin bayanin martaba idan aka kwatanta da kusoshi na hex na waje, yana sa su dace don aikace-aikace tare da iyakanceccen izini ko kuma inda ake buƙatar fitowar ruwa mai tsabta.

Maɓalli na ƙira sun haɗa da:

Shugaban Silindrical tare da hex drive na ciki - yana karɓar daidaitattun maɓallan hex don shigarwa mai ƙarfi mai ƙarfi tare da ɗan ƙaramin kai; Girman tuƙi sun dace da ISO 2936 ko ASME B18.3.

Cikakkun zaren zaren-cikakkun ko ɓangarori - bambance-bambancen zaren cikakken zaren rarraba kaya daidai gwargwado tare da tsayin daka; Bambance-banbance-zaren zaren suna ba da mafi ƙarfi mara zare don aikace-aikacen shear.

Ƙarfe mai ƙarfi mai ƙarfi (8.8 / 10.9 / 12.9) - Matsayin da aka yi da zafi yana tabbatar da ƙarfin juzu'i har zuwa 1,220 MPa, dacewa da kaya mai ƙarfi da haɗin gwiwa mai mahimmanci.

Dacromet surface gama - yana ba da ≥ 1,000 na sa'o'i 1,000 na kariya na fesa gishiri ba tare da ƙwanƙwasa hydrogen ba, yana mai da shi manufa don maɗaukaki masu ƙarfi inda wutar lantarki ba ta dace ba.

3. Takaitawa

Dacromet hex soket bolts sun haɗu da ingantacciyar juriya na lalata tsarin suturar inorganic na Dacromet (cimmakon sa'o'i 1,000-3,000 na kariyar gishiri-spray ba tare da haɓakar hydrogen ba) tare da ƙaƙƙarfan ƙaƙƙarfan ƙaƙƙarfan ƙira, ƙirar ƙirar hex soket. Wannan haɗin kai yana ba da damar ɗorawa abin dogaro a cikin mahalli masu buƙata - daga chassis da tsarin birki zuwa tsarin ruwa da kayan aiki na waje - yayin da ke kiyaye madaidaicin iko da ƙarfi na dogon lokaci. Kamar yadda masana'antu ke ƙara buƙatar kayan ɗamara waɗanda ke daidaita aiki, aminci, da tsawon rai, Dacromet hex socket bolts sun zama zaɓin da aka fi so don injiniyoyi da OEMs a duk duniya.
