Lesale le ile la aroha ka nako e le ngoe 'me la kobeha sebopeho sa helical. Sena se etsa hore washer e sebelise matla a selemo pakeng tsa hlooho ea fastener le substrate, e bolokang washer e le thata khahlanong le substrate le khoele ea bolt e thata khahlanong le nate kapa substrate khoele, e baka ho ferekana le ho hana ho potoloha.

Lisebelisoa tsa selemo ke letsoho le letšehali 'me li lumella khoele hore e tiisoe ka lehlakoreng le letona feela, ke hore, ka lehlakoreng le leng. Ha ho tsamaisoa ho sisinyeha ka letsohong le letšehali, bohale bo phahamisitsoeng bo loma ka tlas'a bokoto kapa linate le karolo eo e fasellelitsoeng ho eona, ka hona ho hana ho fetoha. Ka hona, lihlahisoa tsa selemo ha li sebetse likhoele tsa letsoho le letšehali le bokaholimo bo thata. Hape, ha lia lokela ho sebelisoa hammoho le mochini o hlatsoang a bataletseng tlasa mochini o hlatsoang lihlahisoa nakong ea selemo, kaha sena se arola mochini o hlatsoang lihlahisoa hore o se ke oa fetoha.

Molemo oa li-washer tsa senotlolo sa selemo o lutse ka sebopeho sa trapezoidal sa washer. Ha e petelitsoe ho jara haufi le matla a bopaki a bolt, e tla sotha le ho batalatsa. Sena se fokotsa sekhahla sa selemo sa lenonyeletso se se lumellang ho boloka matla a mangata tlasa maemo a ts'oanang a thothomelo. Sena se thibela ho lokoloha.

Likopo

Sesepa sa selemo se thibela linate le li-bolts hore li se ke tsa fetoha, tsa thelleha le ho tsoa ka lebaka la thothomelo le torque. Li-washer tse fapaneng tsa selemo li etsa mosebetsi ona ka litsela tse fapaneng hanyane, empa mohopolo oa mantlha ke ho ts'oara linate le bolt sebakeng sa tsona. Li-washer tse ling tsa selemo li fihlela mosebetsi ona ka ho loma botlaaseng (bolt) le linate ka lipheletsong tsa tsona.

Li-washer tsa selemo li tloaetse ho sebelisoa lits'ebetsong tse kenyelletsang ho sisinyeha le ho thella ho ka etsahalang ha li fasteners. Liindasteri tse atisang ho sebelisa lihlahisoa tsa selemo li amana le lipalangoang (likoloi, lifofane, likepe tsa metsing). Li-washers tsa nako ea selemo li ka sebelisoa le lisebelisuoa tsa ka tlung tse joalo ka tse sebelisang moea le tse hlatsoang liaparo (mechini e hlatsoang).
