Hele mai nā mea hoʻopaʻa āpau me nā kaha kikoʻī ma ko lākou mau poʻo e kōkua i ka ʻike ʻana i ko lākou kumu, mea, a me ka nui. ʻO nā mea hana Fastener ke kuleana no ka hōʻoia ʻana i ka ʻike maopopo o kā lākou huahana no nā mea kūʻai aku. Hāʻawi kēia alakaʻi i ka ʻike kūpono e kōkua iā ʻoe e hoʻomaopopo a wehewehe i nā kaha i loaʻa ma nā mea hoʻopaʻa.

Pono kēlā me kēia mea hoʻopaʻa i hana ʻia e kahi hui e kau i kahi ʻike kūʻokoʻa ma kona poʻo. Aia paha kēia me ka hua mua a i ʻole ka inoa o ka hui. Ua koi ʻia kēia hana e ka Faster Quality Act e hoʻoulu i ka hilinaʻi i nā mea kūʻai aku e kūʻai nei lākou mai kahi mea hana hilinaʻi.

Nā Kūlana Hoʻopaʻa

ʻO ka hui ʻana o ka honua ma waena o nā ʻoihana i alakaʻi i ka hoʻokumu ʻana i nā hōʻailona maʻamau no nā mea paʻa. Hoʻopili kēia mau maʻamau i ka hoʻohui ʻana i nā mea, nā ana, ka hoʻomanawanui dimensional, a me nā uhi, e hāʻawi ana i ka ʻike piha e pili ana i kēlā me kēia mea paʻa.

Hāʻawi ka American Society for Mechanical Engineers (ASME) i ka palapala ASME B1.1, e hōʻike ana i nā koi no nā wili ʻīniha hui pū. Hoʻohana nui ʻia ʻo ASME ma ke ʻano he maʻamau e nā hui lehulehu.

ʻO nā kūlana ʻē aʻe e wehewehe i nā māka paʻa e pili ana i nā waiwai a me nā waiwai kino. No ka laʻana, wehewehe ʻo SAE J429 i nā koi no nā mea hoʻopaʻa paʻa Papa 2, Papa 5, a me ka Papa 8. ʻO ka ʻike ʻana i ka pae o ka mea hoʻopaʻa paʻa e hāʻawi i ka ʻike e pili ana i kāna mea, ka laulā paʻakikī, nā waiwai electromechanical, a inā pili ia i ka ʻīniha a i ʻole metric standard.

Nā laʻana o SAE J429 Papa 2, Papa 5 a me Papa 8

Ua hoʻokumu ka Society of Automotive Engineers (SAE) i ka maʻamau SAE J429 no nā Mechanical and Material Requirements for Mechanical Fasteners. Kuhi ʻia kēia maʻamau i nā waiwai mechanical a me nā waiwai no nā ʻīniha bolts, screws,studs, sems, aU-bolts, e uhi ana i na ana a hiki i ka 1-½” ke anawaena. ʻO ka piʻi ʻana o ka māka o ka mea hoʻopaʻa e hōʻike ana i ka ikaika tensile kiʻekiʻe, i hōʻike pinepine ʻia e nā laina radial ma ke poʻo o ka mea hoʻopaʻa.

E hoʻomanaʻo, ʻaʻohe mākaʻikaʻi ka papa 2 o SAE J429. Eia kekahi, hiki ke hoʻoponopono ʻia nā māka hana hana ma ke poʻo o ka mea hoʻopaʻa e hoʻokō i ka hōʻike ʻana o kāna papa.
