410 Stainless hlau Countersunk Self Tapping Self Drilling Ntsia Hlau Stainless Hlau Dovetail Ntsia Hlau

Yog tias koj thawj zaug nkag siab txog cov khoom siv ntawm cov ntsia hlau thaum siv lawv, ces koj tuaj yeem siv tau zoo dua. Ntau hom screws muaj cov khoom sib txawv, thiab cov khoom sib txawv ntawm cov khoom siv sib txawv ua rau ntau lub sijhawm uas siv cov ntsia hlau.
1, Self tapping screws: mechanical kev ua tau zoo
1. Lub plawv hardness: tus qauv tus nqi HRC28-38. Thaum kuaj, coj ib ntu 1-2 zaug ntawm nominal txoj kab uas hla ntawm tus Tsov tus tw. Yog hais tias lub nominal ntev luv luv, nws yuav tsum tau embedded ua ntej thiab ces lub hardness yuav ntsuas.
2. Nto hardness: Txheem MIN HV450.
3. Carbonized txheej: Standard 4 # -6 #: 0.05-0.18mm, 8 # -12 #: 0.10-0.23mm, 14 #: 0.13-0.28mm. Lub hom phiaj tseem ceeb ntawm carburization yog txhawm rau txhim kho qhov tawv tawv thiab ua kom lub zog ntawm cov hniav. Yog tias qhov decarburization tob dhau lawm thiab cov carburization tsis txaus, lub zog ntawm cov hniav yuav tsis ua raws li qhov yuav tsum tau ua, uas txhais tau hais tias cov hniav yuav puas thaum lub sij hawm ntsia hlau.
4. Torque: Standard specifications 4 # 5 # 6 # 7 # 8 # 10 # 12 # 14 # A cov hniav 14212835455696145AB hniav 142128354565102165.
5. Screw hauv kev sim: Screw tus kheej tapping ntsia hlau rau hauv ib lub phaj steel nrog cov qhov ntsuas tshwj xeeb. Tus kheej tapping ntsia hlau yuav tsum tsim cov xov sib txuam hauv daim ntawv xeem, thiab cov xov ntawm cov ntsia hlau nws tus kheej yuav tsum tsis txhob deform los yog puas mus txog rau thaum kawg taper xov tag dhau los ntawm cov phaj xeem. Cov ntsia hlau hauv kev sim tsuas yog siv tau rau tus kheej tapping screws ntawm hom AB, B, BP, thiab lwm yam. Raws li IFI cov kev cai, cov phaj xeem yuav tsum tau npaj los ntawm ib qho nyuaj-carbon txias-dov hlau nrog Rockwell hardness ntawm 70-85HRB. Cov txheej txheem tshwj xeeb rau cov hlau phaj, nrog rau cov tuab, muaj nyob hauv cov lus hauv qab no. Qhov ntsuas qhov yuav tsum tau xuas nrig ntaus los yog drilled, nrog ib tug kam rau ua ntawm ± 0.025mm rau cov teev nominal txoj kab uas hla (saib cov lus hauv qab no). Specification 6 # 7 # 8 # 10 # 12 # 1/4 xeem phaj thickness (mm) 1.85-1.953.12-3.234.68-4.84 aperture (mm) ± 0.0252.953.263.454.044.765.50

2 、 Phab ntsa vaj huam sib luag rau tes
1. Lub plawv hardness: tus qauv: HRC24-45.
2. Nto hardness: Txheem: HV600-800.
3. Carbonized txheej: 4 # -6 # 0.05-0.18mm, 8 # -12 # 0.10-0.23, 14 # 0.13-0.28.
4. Khoov degree: yuav tsum tau 150-450
5. Kev kuaj ntsev ntsev: feem ntau MIN 48 teev.
6. Torque: Specification 6 # 7 # 8 # 10 # Torque 21283558.
3. Drill Tail Screw
1. Lub plawv hardness: Txheem: HRC32-40. Peb lub tuam txhab cov khoom tau raug kuaj kom muaj HRC31.7-39.0.
2. Nto hardness: Txheem: HV600-700. Peb lub tuam txhab cov khoom tau raug kuaj nyob ib ncig ntawm HV620.
3. Permeation txheej: 4 # -6 #: 0.05-0.18mm 8 # -12 #: 0.10-0.23mm
