1. Ariā
He taputapu whakarewa te pūtu ono-ā-waho, e mōhiotia ana hoki ko te tīwiri ono-ā-waho, te tīwiri ono-ā-waho, te pūtu ono-ā-waho rānei.

2. Te maimoatanga mata
I roto i te tukanga hanga pūtu, ko te maimoatanga mata tētahi o ngā hononga tino nui. Ka taea e ia te whakatutuki i ngā whakaritenga o te mata o te pūtu, ā, ka whakapai ake i tōna ātete ki te waikura, tōna kaha me tōna āhua ataahua.
He maha ngā momo tikanga maimoatanga mata mō ngā pūtu, ko ngā mea e kitea whānuitia ana ko ēnei e whai ake nei:
Te whakapūmau: Ka rumakina ngā pūtu ki roto i te wairewa konutea, ā, ka pania te konutea ki runga i te mata o ngā pūtu, papatahi i te papatahi mā te tauhohenga hikohiko, kia ātete ai ki te waikura, kia kore ai hoki e pirau.
Te whakapūmau wera-toia: Whai muri i te hanganga o ngā pūtu, ka rumakina ki roto i te wai konutea rewa, ā, ka hangaia he paparanga konutea ki runga i te mata mā te tauhohenga matū hei whakatutuki i ngā pānga ārai-waikura, ātete-waikura me ētahi atu.
Te whakamaimoatanga mangu: Ka hangaia he kiriata waikura konganuku pango ki te mata o te pūtu mā te tauhohenga matū hei whakapai ake i tōna ātete ki te waikura.
Maimoatanga whakapūkara: Ruia te pūtu ki roto i te otinga whakapūkara hei hanga i tētahi kiriata whakapūkara ki runga i te mata hei whakapai ake i tōna ātete ki te waikura.
Te whakamaroketanga: Mā te whakamahana, mā te rehu rānei i te mata, ka hangaia he paparanga paninga pakari ake ki te mata o te pūtu hei whakapai ake i tōna kaha me te ātete ki te kakahu.
Ko ngā tikanga maimoatanga mata pūtu ēnei e whakahuatia ana i runga ake nei. He rerekē ngā tikanga maimoatanga e pā ana ki ngā āhuatanga me ngā whakaritenga tono rerekē. I te wā e whakahaerehia ana te maimoatanga mata pūtu, me whakahaere kia rite ki ngā paerewa me ngā whakaritenga e pā ana kia tino tutuki ai ngā pūtu e maimoatia ana i ngā whakaritenga mahi e tika ana.

3. Te mahi taumata
Ko te tapanga tohu mahi o te pūtu hexagonal o waho he wāhanga e rua o ngā tau, e tohu ana i te uara kaha kume ingoa me te ōwehenga kaha tuku o te rauemi pūtu.
Hei tauira, ko te tikanga o te pūtu me te taumata mahi 4.6:
a. Ko te kaha kume ingoa o te rauemi pūtu ka eke ki te 400MPa;
b. Ko te ōwehenga kaha-pūngao o te rauemi pūtu he 0.6;
c. Ko te kaha tuku ingoa o te rauemi pūtu ka eke ki te taumata 400×0.6=240MPa
Ka taea e ngā pūtu kaha-teitei taumata mahi 10.9, i muri i te maimoatanga wera, te whakatutuki i:
a. Ko te kaha kume ingoa o te rauemi pūtu ka eke ki te 1000MPa;
b. Ko te kaha tuku ingoa o te rauemi pūtu ka eke ki te 1000×0.9=900MPa.

4. Te rerekētanga i waenga i ngā pūtu hexagonal o waho noa me ngā pūtu hexagonal o waho kaha-teitei
Ka taea te whakamahi anō i ngā pūtu ono-hāora noa, engari kāore e taea te whakamahi anō i ngā pūtu kaha-teitei.
Ko ngā pūtu kaha-teitei he mea hanga i te maitai kaha-teitei Nama 45 (8.8s), 20MmTiB (10.9S), ā, he pūtu kua whakamātauhia. Mō ngā momo waku, whakamahia he kī taipana hei whakamahi i te taumahatanga kua tohua, ā, mō ngā momo pēhanga-pehanga, wetekina te pane torx. Ko ngā pūtu noa he mea hanga i te maitai noa (Q235) ā, me whakakaha noa.
Ko ngā pūtu noa he rite tonu ki te taumata 4.4, te taumata 4.8, te taumata 5.6 me te taumata 8.8. Ko ngā pūtu kaha-teitei he rite tonu ki te taumata 8.8 me te taumata 10.9, ko te taumata 10.9 te mea tino kitea.
Kāore e nui ake ngā kōhao tīwiri o ngā pūtu noa i ērā o ngā pūtu kaha. Inaa, he iti noa iho ngā kōhao pūtu noa.
