Ua māhele ʻia ke apo ma kahi kikoʻī a piʻo i ke ʻano helical. ʻO kēia ka mea e hoʻoikaika ai ka mea holoi i ka pūnāwai ma waena o ke poʻo o ka mea hoʻopaʻa a me ke pani, ka mea e hoʻopaʻa paʻa i ka mea holoi ma luna o ka substrate a me ke kaula bolt e paʻa i ka nut a i ʻole ke kaula substrate, e hoʻonui ai i ke kuʻekuʻe a me ke kūpaʻa ʻana i ka hoʻololi ʻana. ʻO nā kūlana kūpono ASME B18.21.1, MAI 127 B, a ʻAmelika Hui Pū ʻIa Kūlana NASM 35338 (MS 35338 a me AN-935 ma mua).

ʻO nā mea holoi puna he helix lima hema a hiki ke hoʻopaʻa ʻia ke kaula ma ka ʻaoʻao ʻākau wale nō, ʻo ia hoʻi ma ka ʻaoʻao uaki. Ke hoʻohana ʻia ka neʻe hoʻohuli ʻana i ka lima hema, nahu ka ʻaoʻao hoʻokiʻekiʻe i ka ʻaoʻao ma lalo o ka bolt a i ʻole ka nati a me ka ʻāpana i hoʻopaʻa ʻia ai, no laila e pale aku i ka huli ʻana. No laila, ʻaʻole pono nā mea holoi puna ma nā kaula lima hema a me nā ʻili paʻakikī. Eia kekahi, ʻaʻole pono e hoʻohana pū ʻia me kahi mea holoi paʻa ma lalo o ka mea holoi puna, no ka mea, hoʻokaʻawale kēia i ka mea holoi puna mai ka nahu ʻana i ka mea e pale ai i ka huli ʻana.

Aia ka pōmaikaʻi o nā mea holoi laka puna i ke ʻano trapezoidal o ka mea holoi. Ke hoʻopili ʻia i nā ukana kokoke i ka ikaika hōʻoia o ka bolt, e wili a palahalaha.

The spring washer prevents nuts and bolts from turning, slipping and coming loose because of vibration and torque. Different spring washers perform this function in slightly different ways, but the basic concept is to hold the nut and bolt in place. Some spring washers achieve this function by biting into the base material (bolt) and the nut with their ends.

Spring washers are commonly used in applications involving vibration and possible slippage of fasteners. Industries that commonly use spring washers are transportation related (automotive, aircraft, marine). Spring washers may also be used in household appliances such as air handlers and clothes washers (washing machines).
