Khoom Taw Qhia

Cov tshuab ntxhua khaub ncaws yog siv los ua kom cov kabmob nto ntawm cov txiv ntoo los yog lub taub hau fastener yog li kis tau lub clamping quab yuam hla ib cheeb tsam loj. Lawv tuaj yeem siv tau thaum ua haujlwm nrog cov ntaub ntawv mos thiab qhov loj lossis qhov tsis sib xws.

Washer loj yog hais txog nws qhov nominal qhov loj thiab yog raws li cov ntsia hlau loj. Nws sab nraud txoj kab uas hla (OD) yog ib txwm loj dua. Qhov loj me thiab OD feem ntau tau teev nyob rau hauv cov zauv feem ntau, txawm hais tias cov zauv ntiv tes yuav siv tau. Thickness feem ntau tau teev nyob rau hauv cov zauv ntiv tes txawm hais tias peb feem ntau hloov nws mus rau feem ntiv tes kom yooj yim.

Grade 2 flat washers should only be used with Grade 2 hex cap screws (hex bolts)—use hardened flat washers with Grade 5 and 8 cap screws. Because Grade 2 flat washers are made of soft, low carbon steel, they will "yield" (compress, cup, bend, etc.) under the higher torque values normally associated with Grade 5 and 8 cap screws. As a result, there will be a reduction in clamping force as the washer yields.

Flat washers feem ntau muaj nyob rau hauv ntau yam ntaub ntawv xws li txhuas, tooj dag, nylon, silicon bronze, stainless hlau thiab hlau. Unplated lossis uncoated steel, hu ua "plain finish," tsis tau kho qhov chaw los tiv thaiv xeb uas tsis yog lub teeb txheej ntawm cov roj rau kev tiv thaiv ib ntus. Yog li ntawd, cov khoom tiav rau cov hlau yog zinc plating thiab kub dip galvanizing.

Daim ntawv thov

Los ntawm lawv cov qauv tsim, kev faib khoom ntawm cov tshuab ntxhua khaub ncaws tuaj yeem tiv thaiv txhua yam kev puas tsuaj rau cov khoom sib dhos. Lub tshuab ntxhua khaub ncaws tiaj tus muaj qhov nyias nyias thiab tiaj tus nrog lub qhov nyob hauv nruab nrab. Hom tshuab ntxhua khaub ncaws no muab kev txhawb nqa rau lub taub hau me me.

Black-oxide steel washers are mildly corrosion resistant in dry environments. Zinc-plated steel washers resist corrosion in wet environments. Black ultra-corrosion-resistant-coated steel washers resist chemicals and withstand 1,000 hours of salt spray.
