O le faʻamoemoe, foliga, ma vaega faʻaoga o U-bolts e aofia ai:
U-bolt faʻaaogaina: e masani ona faʻaaogaina mo paipa vai ma isi paipa faʻapipiʻi faʻapipiʻi poʻo papatusi, e pei o le fausiaina ma le faʻapipiʻiina o vaipuna ipu uʻamea taʻavale, fesoʻotaʻiga faʻainisinia, taavale, vaʻa, alalaupapa, tunnels, nofoaafi, ma isi.
Fa'atusa autu: semi-li'o, sikuea taumatau, tafatolu, tafatolu oblique, ma isi.
O vaega fa'aoga o U-bolts e fa'apea: U-bolts e masani ona fa'aogaina i loli e fa'amautu ai ta'avale ta'avale ma fa'avaa. Mo se faʻataʻitaʻiga, o puna laulaau e fesoʻotaʻi i U-bolts. U-bolts o loʻo i ai le tele o faʻaoga, e pei o le fausiaina ma le faʻapipiʻiina, fesoʻotaʻiga faʻainisinia, taavale, vaʻa, alalaupapa, tunnels, nofoaafi, ma isi.
E le gata i lea, o U-bolts ua faʻaaogaina lautele i fanua faʻaonaponei faʻaonaponei, faigofie ona faʻapipiʻi, tausia, ma sui, ma maua ai le seismic faʻatinoga ma le faʻaogaina o galuega. Pe a filifilia ma faʻaogaina U-bolts, o mea e pei o meafaitino, mamafa, malosi, lanu, ma le malosi faʻamalosi e manaʻomia ona mafaufauina ina ia mautinoa e mafai ona latou faʻafetaui i siosiomaga faʻaoga ma mea e manaʻomia.
