Ol 'fastener' em ol bikpela samting insait long ol 'mechanical connection', na gutpela bilong ol i save mekim gutpela wok long sefti na 'reliability' bilong ol ikwipmen. Long mekim gut olsem ol 'fasteners' i inapim ol standet, ol i mas skelim gut ol dispela samting long rot bilong wanpela 'systematic inspection process'.
Sekim lukluk bilong man em i namba wan step. Ol inspekta i save lukluk o long glas bilong skruim samting na sekim pes bilong 'fastener' long lukim sapos i gat ol hevi olsem ol bruk, ol makmak, ol 'rust', na ol 'burrs'. Ol i lukluk long sekim olsem ol tret i stap gut na i no bagarap, na olsem 'transition' namel long het na 'shank' i gutpela, na bai i no gat ol samting i no stret long wokim.
Dimensenel mesamen i yusim ol tul bilong skelim stret olsem ol 'calipers', 'micrometers', na ol 'thread gauges' long skelim gut ol bikpela samting olsem 'diameter', 'length', na 'thread size'. Ol inspeksen i mas bihainim tru ol droing bilong disain o ol standet bilong indastri (olsem ISO, DIN, na GB) long meksua olsem ol 'dimensional tolerances' i stap insait long ol mak we ol i ken kisim. Long ol spesel-pepos 'fasteners', ol i mas skelim tu ol narapela samting olsem 'hed thickness' na 'groove depth'.
Testing bilong ol samting bilong masin em i wanpela bikpela step. Ol i save yusim wanpela masin bilong skelim strong bilong 'fastener' na 'yield strength' bilong sekim olsem 'load-bearing capacity bilong en i inapim ol mak bilong 'material grade'. Ol i save mekim tu ol 'hardness test' (olsem 'Rockwell' o 'Brinell' 'hardness') bilong lukim olsem 'heat treatment process' bilong ol samting i bihainim ol standet. Long ol samting bilong pasim olsem ol bolt na nat, ol i mas mekim 'torque-preload test o 'screw-on tes tu long skelim wok bilong bungim ol.
Non-testing we i no inap bagarapim em i gutpela long ol aplikesen we i gat planti wok. Ol i save yusim 'magnetic particle testing' (MT) o 'penetrant testing' (PT) long painim ol 'surface' o klostu long '-'mak; ol i save yusim 'ultrasonic testing' (UT) o 'radiographic testing' (RT) long painim ol hevi insait long bodi, moa yet long ol strongpela samting o ol bikpela samting bilong pasim.
Ol wok bilong skelim 'surface treatment' i gat wok bilong skelim 'coating thickness' (olsem 'galvanizing'), wok bilong skelim 'salt spray' (olsem 'corrosion resistance'), na skelim ol samting bilong envairomen (olsem 'hexavalent chromium content') long lukim olsem 'corrosion resistance' na i bihainim lo.
Long pinis, olgeta tes data i kamap wanpela ripot na ol kwaliti inspekta i sainim na konfemim. Ol i save rausim ol samting we i no wok gut na painim as bilong en. Ol kwalifait prodak tasol i ken go insait long 'packaging' o 'assembly'. Dispela standet proses i save mekim gutpela wok long mekim kwaliti i stap wankain na sefti bilong ol 'fasteners'.
