Countersunk Head Phillips Self Drilling Screws

Kune akawanda marudzi ewinged self-drilling screws, asi ese ane hunhu hwakafanana. Pane maitiro mashanu makuru. Iyo inotevera hardware inotsanangura zvinhu zvishanu zvewinged self-drilling screws:

1. Kazhinji yakagadzirwa nesimbi yakasvibiswa (99% yezvinhu zvose). Inogonawo kushandiswa pasimbi isina tsvina kana isina-ferrous simbi.

2. Self-drilling screws nemapapiro inofanira kunge ichipisa. Hardware inokuudza kuti kabhoni simbi yekuzvirova-rova screws inofanirwa kuve yakavharwa, uye simbi isina-yega-yekurovera screws ine mapapiro embambo inofanirwa kuve yakasimba mhinduro yakaoma. Kuti uite self-tapping screws inosangana ne mechanical properties uye kushanda kunodiwa nechiyero.

3. Winged self-drilling screw zvigadzirwa zvine kuoma kwepamusoro uye kusimba kwakanaka kwepakati. Ndiko kuti, "zvakapfava mukati uye zvakasimba kunze". Iyo hardware inokuudza kuti ichi chinhu chikuru chekushanda kwezvinodiwa zvekuzvirovera mbambo dzemapapiro. Kana kuomarara kwepamusoro kwakaderera, hakugone kukwizwa mukati me matrix; kana iyo core iine kuomarara kwakashata, inotyoka kana yangoiswa screw uye haigone kushandiswa. Naizvozvo, "yakapfava mukati uye yakaoma kunze" ndeye self-drilling screws ane mapapiro embambo kuti asangane nekuita zvinodiwa.

4. Nzvimbo yeBest Self Drilling Screw With Wings zvigadzirwa zvinoda kuchengetedzwa kwepamusoro kurapwa, kazhinji electroplating kurapwa. Iyo hardware inokuudza kuti pamusoro pezvimwe zvigadzirwa zvinoda kurapwa nephosphate (phosphating). Muenzaniso: Self-drilling screws ane mapapiro embambo pamadziro emadziro ane phosphated
