dema grey phosphate bugle musoro self tapping drywall screw yehuni dzesimbi

Self Drilling Screws zvimisikidzo zvine akavakirwa-mukati ekuchera zvibodzwa, akagadzirwa ane dhiri bhiti rakaumbwa muromo rinogona kupinda zvakananga zvinhu zvakaita sesimbi, huni, uye purasitiki pasina kudiwa kwekutanga kudhirowa. Kurumidza kugadzirisa kunowanikwa kuburikidza nekupindirana kwetambo uye substrates, iyo inoshandiswa zvakanyanya muminda yakadai sekuvaka, fenicha, uye mekiniki kugadzira. Iine maitiro ekushanda kwepamusoro, kuchengetedza nguva, uye simba guru.

Technical Parameters uye Sarudzo Yekutungamira

Material: Carbon simbi (pamusoro galvanized/phosphated), Stainless simbi (304/316, corrosion-resistant)

Zvinowanzotsanangurwa zvedhayamita (mm): Φ 2.5, Φ 3.5, Φ 4.2, Φ 5.0 (zvichienderana nehupamhi hwe substrate, mashizha esimbi anonyanya kushandiswa nehupamhi hwe Φ 3.5-4.2)

Kureba (mm) 10-150mm (kuve nechokwadi chekuruma kushoma kudzika kwe3-5mm mushure mekupinda muzasi)

Thread type: shinda imwe chete (yakanyanya kusimba simba), kaviri shinda (nekukurumidza kupinda)

Musoro wemhando: countersunk (flat installation), disc musoro (high pressure), hexagonal head (simba rakasimba rinochinjika)

Kurapa kwepamusoro: chena zinc plating (yakakosha kudzivirira ngura), phosphating dema (inodzivirira kupfeka), Dacromet (yakakwira corrosion resistance)
