Ibicuruzwa: Umuyoboro wa Steel Square Umutwe
Ibikoresho: Byakozwe mu byuma 304 bidafite ingese, iyi miyoboro ifite imiti irwanya imiti kandi irashobora kuba magnetique yoroheje. Bazwi kandi nka A2 ibyuma bidafite ingese.
Ubwoko bwumutwe: Umutwe wa kare.
Uburebure: bipimirwa munsi yumutwe.
Ubwoko bwinsanganyamatsiko: Urudodo ruto, Urudodo rwiza. Urudodo ruto ni urwego rwinganda; hitamo iyi screw niba utazi ikibuga cyangwa insinga kuri santimetero. Utudodo twiza kandi twiza-twinshi twashyizwe hafi kugirango twirinde guhindagurika; urudodo rwiza, nibyiza kurwanywa.
Gushyira mu bikorwa: Hafi ya kimwe cya kabiri cyimbaraga zimbaraga ziciriritse, izo screw zirashobora gukoreshwa mubikorwa byoroheje byorohereza porogaramu, nko kubona ibibaho. Impande nini zoroheje zoroha gufata hamwe nigitereko kandi ntizizunguruka mu mwobo wa kare.
Ibisanzwe: Imiyoboro yujuje ASME B1.1, ASME B18.2.1, yubahiriza ibipimo ngenderwaho.
