Kenyelletso ea Sehlahisoa
Li-washer tse bataletseng di sebedisoa ho eketsa bokahodimo ba linate kapa hlooho ya seqhomane ka tsela eo ho hasanya matla a ho kokota sebakeng se seholoanyane. Li ka ba molemo ha u sebetsa ka thepa e bonolo le masoba a bōpehileng ka boholo kapa a sa tloaelehang.
Saese ea washer e bolela boholo ba lesoba la eona mme e ipapisitse le boholo ba screw. Bophara ba eona bo ka ntle (OD) bo lula bo le boholo. Boholo le OD hangata li hlalosoa ka lisenthimithara tse fokolang, leha ho le joalo ho ka sebelisoa lisenthimithara tsa decimal. Botenya hangata bo thathamisitsoe ka lisenthimithara tsa decimal le hoja hangata re bo fetolela ho lisenthimithara tse fokolang bakeng sa boiketlo.
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.
Li-washer tse bataletseng li fumaneha hangata ka lisebelisoa tse fapaneng tse kenyelletsang aluminium, koporo, nylon, boronse ea silicon, tšepe e sa hloekang le tšepe. Tšepe e sa apesoang kapa e sa apesoang, eo ho thoeng ke "phello e hlakileng," ha e so ka e phekoloa ka holim'a metsi ho thibela mafome ntle le ho roala ha oli bakeng sa tšireletso ea nakoana. Ka lebaka leo, lisebelisoa tse tloaelehileng tsa tšepe ke "zinc plating" le "hot dip galvanizing".
Lisebelisoa
Ka moralo oa bona, thepa ea kabo ea li-washer tse hlakileng e ka thibela tšenyo ea mofuta ofe kapa ofe libakeng tse bokaneng. Washer e bataletseng e na le bokaholimo bo tšesaane ebile bo bataletse ka lesoba bohareng. Mofuta ona oa washer o fana ka tšehetso ho sekoti se senyenyane sa hlooho.
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.
