2026-08-03

1. Icyiciro cya 8.8 - Hagati-Yimbaraga Zikomeye Icyiciro Cyihuta

1.1 Kumenyekanisha 8.8

Ikimenyetso "8.8" nicyiciro cyumutungo wasobanuwe na ISO 898-1, amahame mpuzamahanga agenga imiterere yubukanishi bwibyuma bya karubone hamwe nicyuma gifata ibyuma. Sisitemu y'imibare ibiri ikubiyemo ibintu bibiri by'ingenzi bikoreshwa:

Digit Imibare ya mbere (8): Yerekana kimwe cya cumi cyingufu zizina muri megapascals → 8 × 100 = 800 MPa imbaraga ntoya.

Digit Umubare wa kabiri (.8): Yerekana igipimo cy'umusaruro → 0.8 × 800 = 640 MPa imbaraga nke z'umusaruro.

Icyiciro cya 8.8 nicyuma gikoreshwa cyane mubikorwa rusange-byubatswe byubatswe kwisi yose, bitwikiriye ibishashara, imigozi ya hex, imashini itwara abagenzi, ibyuma bya sitidiyo, hamwe nudupapuro twuzuye twuzuye two kubaka ibyuma, guteranya amamodoka, hamwe nimashini rusange.

1.3 Ibikoresho bisabwa

Guhitamo ibikoresho bibisi nibyo shingiro ryo gutanga ibyiciro byizewe byo mu cyiciro cya 8.8. Ibyuma bikurikira, bifatanije na Q&T ikwiye, bigera kumikorere ya Grade 8.8:

● 35 # Icyuma giciriritse-Carbone - Bikwiranye na diameter ntoya (≤ M16). Ikiguzi-cyiza, gukomera bihagije nyuma yikibazo.

. Imashini nziza, imiterere yubukanishi nyuma ya Q&T.

● 40Cr Alloy Steel - Bikunzwe kuri binini-diameter nini (M20 +). Kwiyongera kwa Chromium bitezimbere gukomera hamwe no guhuza ibice bitandukanye.

Icyiciro	Tensile (MPa)	Umusaruro (MPa)	Ibikoresho Byasabwe
4.6	400	240	Ibyuma bya karubone bike, bidashyushye
4.8	420	340	Ibyuma bya karubone bike, bikonje
8.8	800	640	35 # / 45 # Icyuma cya Carbone, 40Cr Amashanyarazi; Ikibazo
10.9	1,040	940	40Cr, 35CrMo, 42CrMo, SCM435; Ikibazo
12.9	1,220	1,100	42CrMo4 / SCM440, 35CrMoV; Ikibazo 39-44 HRC

2. Hex Bolts - Kwihuta cyane

2.1 Hex Bolt ni iki?

Hex bolt (umutwe wa mpande esheshatu) ni umugozi wihuta ufite umutwe wimpande esheshatu, wagenewe kwinjizwa mu mwobo mubice byateranijwe kandi bigashyirwaho nimbuto yo guhuza. Uburinganire bwa hexagonal butuma wrench cyangwa sock itangirana impande nyinshi, bigatuma iba ubwoko bukoreshwa cyane kandi bukoreshwa cyane mubikorwa byose. Ibintu bibiri by'ingenzi birahari:

● Hex Bolt (ISO 4014 / DIN 931) - Igice kimwe: umurongo udasomwe igice cya shank gitanga imbaraga zoguhuza no guhuza, byiza muburyo bwo guhuza imiterere.

Sc Hex Cap Screw (ISO 4017 / DIN 933) - Urudodo rwuzuye: insinga zikoresha uburebure bwose, zikwiranye nibisabwa bisaba guhuza cyane.

2.2 Ibisanzwe Hex Bolt Ubwoko & Ibihinduka

Head Hex Head Bolt / Cap Screw - Umutwe usanzwe ufite impande esheshatu; byinshi, bikoreshwa mubwubatsi, imashini, imodoka.

● Hex Flange Bolt - Imashini imesa isa na flange munsi yumutwe; ikwirakwiza clamp umutwaro, ikuraho isabune itandukanye.

He Hex Hex Bolt (ASTM A325) - Umutwe munini wo guhuza ibyuma byubaka; byerekanwe mu bipimo byo muri Amerika y'Amajyaruguru.

● Hex Lag Bolt / Gutwara Bolt - Impinduka zihariye kubiti-ibyuma-bihuza ibiti.

3. Icyiciro cya 8.8 Hex Bolts - Guhitamo & Gusaba

3.1 Kuvura Ubuso

Guhitamo uburyo bwo kuvura biterwa nibidukikije bikora nibisabwa kurinda ruswa. Amahitamo asanzwe yo mu cyiciro cya 8.8 hex arimo:

Pl Gutera Zinc (Electroplated) - Kurwanya ruswa mu bukungu, iringaniye; guhitamo bisanzwe murugo no mu bidukikije byoroheje.

● Ashyushye-Dip Galvanizing - Ipine ya zinc itwikiriye hanze no mu nyanja; bisaba kurenza urugero.

Ating Dacromet Coating - Chromium idafite, ibidukikije byangiza ibidukikije; biruta umunyu-spray kurwanya birwanya hydrogène. Icyifuzo cyimodoka nuburyo bukoreshwa.

● Ruspert Coating - Ibice bitatu-ngenga / zinc; ikirere cyiza cyane, gikunze kugaragara mubipimo byinganda zubuyapani.

3.2 Amabwiriza yo Kwishyiriraho

● Koresha guhuza icyiciro cya 8 nuts kugirango imbaraga zihuze.

Koresha uburyo bwihariye bwo gukomera kuri buri rupapuro rwamakuru; gukabya gukabije ingaruka bolt gutsindwa.

Gusiga amavuta mbere yo gukoresha torque - coefficient de fraissique igira ingaruka zikomeye kubigeraho mbere.

● Menya neza ko byibuze umugozi umwe wuzuye urenga hejuru yimbuto nyuma yo gukomera.

Irinde gukoresha Bolt yo mu cyiciro cya 8.8 muburyo bukomeye nyuma yo gupakira ibintu byuzuye.

3.3 Ibipimo & Icyemezo

Icyiciro cya 8.8 hex yakozwe kandi igeragezwa hakurikijwe:

● ISO 898-1 - Ibikoresho bya mashini yimashini ikozwe mubyuma bya karubone nicyuma kivanze.

● ISO 4014 - Hex bolts hamwe na shank yomutwe igice (ibipimo).

● ISO 4017 - Hex cap screw ifite imigozi yuzuye (ibipimo).

Certificate Impamyabumenyi yuzuye y'ibizamini (MTC) kuri EN 10204 3.1 iboneka ubisabwe.
