Iwe unoda pre drill self drilling screws?

Self-drilling screwsakagadzirirwa kuchera maburi azvo sezvaanokwenenzverwa munzvimbo, izvo zvinoreva kuti kudhirowa kwekutanga hakuwanzo kudiwa. Nekudaro, zvichienderana nekukora uye kuoma kwechinhu chiri kupindirwa mukati, pre-drilling ingave yakakosha kuti uve nechokwadi chekuisa kwakaringana.

Hezvino zvinhu zvishoma zvekufunga nezvazvo kana uchifunga kuti wofanoboora here usati washandisa self-drilling screws:

Ukobvu hwezvinhu: Pazvinhu zvakatetepa zvakanyanya senge sheet simbi, pre-drilling kazhinji haifanirwe. Nekudaro, kune zvakakora zvinhu zvakaita sehuni dzakaoma kana matanda akacheneswa, zvingave zvakafanira kufanoboora kudzivirira kupatsanura kana kuputika.

Kuoma kwezvinhu: Zvimwe zvinhu zvakaoma kana kuomarara kupfuura zvimwe, zvichiita kuti zvinyanye kunetsa kurovera mazviri. Mune izvo zviitiko, kufanochera gomba rekutyaira kunogona kuita kuti zvive nyore kuisa iyo yekuzviboora screw.

Screw size: Saizi yekuzvirovera screw inozokanganisawo kana pre-drilling ichidikanwa. Zvikurisa zvikurisa zvingada kufanocherwa kuti ive nechokwadi chekuti akaiswa zvakanaka uye zvakachengeteka.

Kazhinji, kana zvinhu zviri kupindirwa mukati zvakatetepa uye zvisina kuomesesa, kazhinji zvakachengeteka kushandisa self-drilling screws pasina pre-drilling. Nekudaro, kune zvinhu zvakaoma kana zvakakora, kufanorovera gomba rekutyaira kungave kuri madikanwa kuti uve nechokwadi chekuisa kwakaringana. Neimwe nzira, munhu anogona kushandisa masiruuru anocheka tambo dzawo muzvinhu pane kudhirowa. Zvinogara zvakanaka kutevedzera mirairo yemugadziri yemasiruu uye zvinhu zviri kushandiswa, uye kuyedza masiruu munzvimbo diki usati waenderera neprojekiti hombe kuti uve nechokwadi chekuti zviri kuita sezvakarongwa.
