Mheni ine hexagonal inoboorera muswe ine pad self tapping galvanized dovetail screw color simbi tile chipikiri chiboorera muswe chipikiri 6 Corner drill tail screw.

Kana iwe uchigona kutanga wanzwisisa ma mechanic properties ye screws paunenge uchizvishandisa, saka unogona kuzvishandisa zviri nani. Mhando dzakasiyana dzema screws dzine akasiyana mechanical properties, uye akasiyana mechanical zvivakwa zvinoguma nezviitiko zvakasiyana umo ma screws anoshandiswa. 1, Self tapping screws: Mechanical performance zvinodiwa 1. Core hardness: standard value HRC28-38. Paunenge uchiyedza, tora chikamu 1-2 nguva yezita dhayamita kubva kumuswe. Kana urefu hwezita hwakanyanya kupfupika, hunogona kuiswa pekutanga uye ipapo kuoma kunogona kuyerwa. 2. Kuoma kwechiso: Standard MIN HV450. 3. Carbonized layer: Standard 4 # -6 #: 0.05-0.18mm, 8 # -12 #: 0.10-0.23mm, 14 #: 0.13-0.28mm. Chinangwa chikuru che carburization ndechekuwedzera kuoma kwepamusoro uye kuve nechokwadi chekusimba kwemeno. Kana iyo decarburization yakadzika zvakanyanya uye iyo carburization haina kukwana, simba remeno haringasviki zvinodiwa, izvo zvinoreva kuti mazino achakuvadzwa panguva yescrew mukuedzwa. 4. Torque: Yakajairwa zvirevo 4 # 5 # 6 # 7 # 8 # 10 # 12 # 14 # A mazino 14212835455696145AB mazino 142128354565102165. 5. Chikuro mubvunzo: Kara iyo ndiro yega yekugogodza bvunzo mugomba bvunzo. Iyo self taper screw inofanira kuumba shinda inoenderana mutest plate, uye shinda yescrew pachayo haifanire kukanganiswa kana kukuvadzwa kusvika tambo yekugumisira yanyatsopfuura nemutest plate. Iyo screw in test inongoshanda kune self tapping screws emhando AB, B, BP, zvichingodaro. Zvinoenderana nemirairo yeIFI, ndiro yekuyedza inofanira kugadzirwa kubva kusimbi yakaoma yakaderera-kabhoni inotonhora-yakakungurutswa simbi ine Rockwell kuomarara kwe70-85HRB. Izvo zvakajairwa zvemahwendefa esimbi, kusanganisira ukobvu, zvinoratidzwa mutafura iri pazasi. Iwo maburi ebvunzo anofanirwa kubaiwa kana kudhiriwa, nekushivirira kwe ± 0.025mm kune yakatsanangurwa dhayamita yezita (ona tafura pazasi). Tsanangudzo 6 # 7 # 8 # 10 # 12 # 1/4 bvunzo ndiro ukobvu (mm) 1.85-1.953.12-3.234.68-4.84 aperture (mm) ± 0.0252.953.263.454.044.765.50.
