Mea ma Togafitiga Laufanua

Mea masani

Carbon sila: Tau maualalo, malosi maualuga, luga e manaʻomia togafitiga puipuia ele, e pei o le galvanizing ma Dacromet.

u'amea u'amea (304/316): Malosi tete'e a'a, talafeagai mo si'osi'omaga susu po'o vaila'au.

Alumini u'amea/kopa: Mamafa po'o fa'ata'ita'iga mana'oga fa'ata'ita'iga, ae fa'aitiitia le malosi.

Togafitiga i luga

Galvanization: vaevaeina i electroplating (lanumoana ma paʻepaʻe zinc, lanu zinc) ma vevela-dip galvanizing, e masani ona ele tetee, talafeagai mo siosiomaga totonu.

Dacromet (zinc chromium coating): Leai se lamatiaga o le hydrogen embrittlement, maualuga le vevela, faʻafefete, faʻaaogaina i taavale ma fafo.

Phosphating: faʻateleina le lubricity ma faʻaitiitia faʻalavelave faʻapipiʻi.

Faʻapipiʻiina o le nailoni: faʻapipiʻi, faʻamalo faʻamalo, masani ona faʻaaogaina i masini eletise.

Talosaga Fields

Gaosi ta'avale: O vaega u'amea, fa'afale totonu, ma fa'amau uaea e tatau ona fa'ate'ia ma fa'amalo.

Mea fa'aeletonika: Fa'aputuga laupapa ma atigi fa'apotopotoga, e masani lava la'ititi (M2-M4) e 'alofia ai le fa'alavelave fa'aoso.

Teuga faufale: Fa'apipi'iina o pa'u u'amea lanu, faitoto'a ma fa'amalama fa'amalama alumini, ma le puipuiga o luga o lau'au mai le maosiosia.

Meafaigaluega faʻainisinia: panels ma faʻamaufaʻailoga ua faʻapipiʻiina e faʻafefe ai siʻosiʻomaga teteʻe.

Fa'amatalaga ma tulaga

Fa'amatalaga masani

Igoa fa'aigoa: M2 i le M12 (masani M4-M6).

Umi ole laina: 6mm i le 100mm, faʻatatau ile manaʻoga o talosaga.

Flange diameter: e masani lava 2-3 taimi le lautele o le sikulima (e pei o le M5 flange luga lautele e uiga i le 10-15mm).

tulaga fa'ava-o-malo

National standard: GB/T 15856.4 (Pan head cross flange self tapping screws).

Fa'a Siamani: DIN 7500 (Fa'ainisinia fa'apitoa mo fa'ailoga fa'apipi'i).

Tulaga Amerika: ANSI / ASME B18.6.4, SAE J78 (taʻavale taʻavale).
