black gray phosphate bugle head self tapping drywall screw for metal metal

I-Self Drilling Screw yiziqinisi ezinekhono lokubhola eyakhelwe ngaphakathi, eliklanywe ngethiphu elimise okwe-drill elingangena ngokuqondile ezintweni ezifana nensimbi, ukhuni, nepulasitiki ngaphandle kwesidingo sokumba ngaphambili. Ukulungiswa okusheshayo kufinyelelwa ngokuhlangana kwemicu nama-substrates, asetshenziswa kakhulu emikhakheni efana nokwakha, ifenisha, kanye nokukhiqizwa kwemishini. Inezici zokusebenza kahle okuphezulu, ukonga isikhathi, namandla aphezulu.

Imingcele Yezobuchwepheshe kanye Nomhlahlandlela Wokukhetha

Material: Insimbi ye-Carbon (i-surface galvanized/phosphated), insimbi engagqwali (304/316, ukumelana nokugqwala)

Ukucaciswa okuvamile kobubanzi (mm): Φ 2.5, Φ 3.5, Φ 4.2, Φ 5.0 (kuye ngokuthi ubukhulu be-substrate, amashidi ensimbi asetshenziswa kakhulu ngobubanzi obungu-Φ 3.5-4.2)

Ubude (mm) 10-150mm (ukuqinisekisa ubuncane bokujula kokuluma okungu-3-5mm ngemva kokungena kwi-substrate)

Uhlobo lwentambo: intambo eyodwa (amandla aqinile aphezulu), intambo ephindwe kabili (ukungena ngokushesha)

Uhlobo lwekhanda: i-countersunk (ukufakwa okuyisicaba), ikhanda le-disc (ukucindezela okuphezulu), ikhanda eline-hexagonal (ukuguquguquka kwethuluzi eliqinile)

Ukwelashwa okungaphezulu: i-zinc plating emhlophe (ukuvimbela ukugqwala okuyisisekelo), i-phosphating emnyama (ukumelana nokugqoka), i-Dacromet (ukumelana nokugqwala okuphezulu)
