3. Cov khoom tseem ceeb zoo

90 ° countersunk taub hau zais kev teeb tsa: tapered countersunk taub hau qauv, ntsia hlau taub hau saum npoo yog yaug nrog workpiece tom qab zawm, thiab tsis muaj qhov cuam tshuam. Nws yog qhov zoo dua rau kev kho kom zoo nkauj sab hauv thiab kho kom zoo nkauj hauv tsev uas yuav tsum tau ua kom zoo nkauj.

Suav lub teb chaws tus qauv tus kheej-drilling dual-lub hom phiaj kev ua tau zoo: nruj me ntsis benchmarked tiv thaiv Suav teb chaws tus qauv drilling tsis, nws muaj peev xwm ncaj qha xyaum 0.7 ~ 6mm tuab txias-kuav los tiag steel nplooj ntawv thiab zinc plated hlau los xij. It is also suitable for fastening solid wood, density boards, and plastic parts, reducing the number of customer stock items.

4. Kev tswj cov khoom lag luam zoo thiab cov kev pabcuam txhawb nqa

Txhua lub teb chaws Suav tus qauv specifications muaj nyob rau hauv Tshuag, tsis tu ncua kev txiav txim yog xa nyob rau hauv 48 teev, thiab me me-batch qauv thiab tag nrho cov thawv export txiav txim tau txais. Ua ntej tawm hauv lub Hoobkas, qhov kev xyaum taw tes hardness, Phillips recess lub zog, xov raug, txheej adhesion, thiab lwm yam yog randomly tshuaj xyuas ib tug los ntawm ib tug raws li Suav teb cov qauv, thiab cov khoom puas xws li chipped hau thiab cov hniav tsis tiav yog tshem tawm. Nws tuaj yeem raug ntim rau hauv cov khoom ua tiav nrog peb lub Hoobkas lub tshuab ntxhua khaub ncaws thiab lub caij nplooj ntoos hlav ntxhua khaub ncaws, muab ib-nres fastening accessories; nws txhawb customized ncua thiab tshwj xeeb-zoo li tus kheej-drilling screws raws li drawings los yog cov qauv, thiab ruaj khov muaj peev xwm ua kom lub sij hawm ntev kev txiav txim renewals rau txawv teb chaws cov neeg muas zaub.
