Ha e le hantle, liboutu tsa Hexagon li bua ka li-fasteners tse nang le hlooho e nang le screw. Liboutu li arotsoe haholo ka liboutu tsa tšepe le liboutu tsa tšepe tse sa hloekang ho latela thepa. Iron e arotsoe ka limaraka, 'me limaraka tse tloaelehileng ke 4.8, 8.8, le 12.9. Tšepe e sa hloekang e entsoe ka liboutu tsa SUS201, SUS304 le SUS316.
Sete e felletseng ea liboutu tsa hexagon e na le hlooho ea bolt, nate, le gasket e sephara.
Hexagon head bolts ke hexagonal head bolts (partial threads) – c liboutu tsa hlooho tse hexagonal (full threads) – c grade, tse tsejoang hape e le hexagonal head bolts (rough) hexagonal head bolts, black iron screws. Litekanyetso tse sebelisoang hangata ke: sh3404, hg20613, hg20634, joalo-joalo.
Hexagon head bolt (e khutsufalitsoeng joalo ka hexagon bolt) e na le hlooho le molamu oa khoele (
Litekanyetso tse felletseng tsa liboutu tse sebelisetsoang ho hokahanya meaho ea tšepe li arotsoe ka limaraka tse fetang 10, ho kenyeletsoa 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 le 12.9. Har'a tsona, liboutu tsa sehlopha sa 8.8 ho ea holimo, tse entsoeng ka tšepe e nang le carbon alloy e tlase kapa tšepe e bohareng ea k'habone 'me li fumana kalafo e nepahetseng ea mocheso (ho tima le ho futhumatsa), hangata li bitsoa liboutu tse matla haholo, athe tse ling kaofela li bitsoa hangata. ho joalo ka liboutu tse tloaelehileng. Letšoao la boemo ba ts'ebetso ea bolt le na le likarolo tse peli tsa linomoro tse emelang boleng ba matla a tensile le karolelano ea lihlahisoa tsa thepa ea bolt. Se latelang ke mohlala.
Moelelo oa liboutu tse nang le boemo ba ts'ebetso ea 4.6 ke:
Matla a ho tsitsa a lebitso la thepa ea bolt a fihla ho 400 mpa;
2. Karolelano ea matla a lihlahisoa tsa thepa ea bolt ke 0,6;
3. Matla a tlhahiso ea tlhaho ea thepa ea bolt ho fihla ho 400 × 0.6 = 240MPa boemo
Liboutu tse matla tse phahameng tse nang le boemo ba ts'ebetso ea 10.9, 'me thepa ka mor'a kalafo ea mocheso e fihla:
1. Matla ao ho thoeng ke matla a bolt a fihla ho 1000MPa;
2. Karolelano ea matla a lihlahisoa tsa thepa ea bolt ke 0,9;
Matla a tlhahiso ea tlhaho ea thepa ea bolt e fihla ho 1000 × 0.9 = 900MPa boemo
Moelelo oa limaraka tse fapaneng tsa ts'ebetso ea bolt ke maemo a amohelehang machabeng. Liboutu tse nang le boemo bo ts'oanang ba tlhahlobo ea ts'ebetso ea sehlahisoa li na le ts'ebetso e ts'oanang ho sa tsotelehe thepa le tšimoloho ea tsona, 'me ho ka khethoa feela kereiti ea ts'ebetso ea polokeho bakeng sa moralo.
