Hauv peb lub neej niaj hnub, sab nrauvhexagonal ntsia liaj qhov roojyog ib qho kev lag luam bolt ntau heev. Thaum kho kom zoo nkauj, peb feem ntau siv sab nraud hexagonal bolts. Yog tias peb nkag siab txog cov qauv thiab qhov ntau thiab tsawg ntawm sab nraud hexagonal bolts, nws yuav ua rau nws yooj yim rau peb xaiv bolts uas haum rau peb cov kev xav tau.
Txheem rau sab nraud hexagonal bolts
Lub teb chaws tus qauv GB/T5782-86 qhia cov xov specifications rau sab nraud hexagonal bolts: cov xov specifications yog M3 ~ M64, qib A thiab B hexagonal taub hau bolts. Ntawm lawv, Chav A yog tsim rau bolts nrog D<=24 and L<=10D or L<=150mm (whichever is smaller); B-grade is suitable for bolts with D>24 or L>10D or L>150 (qhov twg me dua).
Dimensions ntawm sab nraud hexagonal bolts
Cov txheej txheem rau sab nraud hexagonal bolts suav nrog DIN, ANSI, BS, thiab GB, thiab stainless hlau lossis carbon hlau tuaj yeem xaiv los ua cov khoom siv. Txoj kab uas hla yog 5mm ~ 20mm, 1/4 "~ 3/4", qhov ntev yog 8mm ~ 200mm, thiab 5/16 "~ 8". Xov specifications muaj xws li metric, ntxhib, nplua, thiab imperial. Muaj cov tshuab ua haujlwm zoo ntawm 4.8, 5.8, 6.8, 8.8, 9.8, 10.9, thiab 12.9. Cov kev xaiv kho deg muaj xws li ntuj xim, galvanizing, blackening, thiab nickel plating.
Tsis tas li ntawd, lub taub hau loj tuaj yeem sib txawv nyob ntawm qhov tshwj xeeb ntawm sab nrauvhex bolts. Tshwj xeeb, raws li hauv qab no:
