Steel Structure Hex Bolts

 

Steel qauv hex boltsyog ib feem tseem ceeb ntawm kev tsim kho kev lag luam. Cov bolts siab zog no yog siv los koom nrog cov tswv cuab steel ua ke los tsim cov qauv ruaj khov thiab muaj zog. Hex bolts yog qhov kev xaiv nrov vim tias lawv yooj yim siv thiab ua haujlwm ntev.

Khoom npe:Steel qauv hex bolts

Lwm lub npe: flange bolts thiab ceev, hex flange bolts ceev, steel qauv thauj tog rau nkoj bolts, siab zog txhuam tuav bolts

Khoom siv: Carbon steel

Qib: 8.8 / 10.9 / 12.9 qib

Txheej: Hexagonal taub hau thiab flange thiab ntsia hlau

Nto: Oxidation thiab blackening

1. Lub sab sib koom ua ke ntawm lub taub hau loj hexagonal siab lub zog bolts muaj ib lub ntsia liaj qhov rooj, ob lub tshuab ntxhua khaub ncaws thiab ib lub txiv ntoo. Cov bolts, txiv ntseej thiab ntxhua khaub ncaws yuav tsum tau siv raws li lub rooj.

Kev sib tw bolts, ceev thiab washers

2. Lub hardness ntawm loj hexagon taub hau siab zog bolts yuav tsum ua raws li cov kev cai nyob rau hauv lub rooj.

Bolt hardness

Tom qab kev kho cua sov, cov khoom siv hexagonal loj tuaj yeem ncav cuag lub zog tensile nominal ntawm 1000MPa; lub nominal yield zog ntawm cov khoom loj hexagonal ntsia liaj qhov rooj tuaj yeem ncav cuag 1000 × 0.9=900MPa.

Loj hexagonal bolts (1) Npaj wrenches, bolts ib ntus, overshoots, hlau txhuam thiab lwm yam cuab yeej. Qhov tseem ceeb tshaj plaws yog kev kho ntawm kev tsim kho torque. Lub torque wrench siv yuav tsum tau calibrated ua ntej ua hauj lwm, thiab nws tsuas yog siv tau tom qab lub torque tau calibrated. Kev kho torque yuav tsum raug xaiv los ntawm tus neeg xaiv; (2) Thaum xaiv qhov ntev ntawm lub taub hau loj hexagonal lub taub hau siab lub zog, xav tias cov khoom siv hlau siv hauv kev ua cov hlau feem ntau muaj qhov ua tau zoo, thiab ntau cov ntaub ntawv raug hloov, cov loj loj yog siv los ntawm cov me me, thiab nyias nyias. feem ntau yog siv. Yog li ntawd, muaj ntau yam tshwm sim uas tag nrho cov tuab ntawm kev sib txuas nce los ntawm 3 ~ 4 hli. Yog li ntawd, qhov ntev ntawm lub siab-lub zog bolt yuav tsum tau xaiv. Feem ntau, nws yog qhov tsim nyog kom muaj 2 ~ 3 buckles tom qab zawm, thiab tom qab ntawd phim lub teeb raws li xav tau.
