1. Izina
Utuzu tw’umutwe w’umuzunguruko w’inyuma, twitwa kandi hexagon socket head bolts, cup head screws, na hexagon socket head screws, dufite amazina atandukanye, ariko bivuze ikintu kimwe. Utuzu tw’umutwe w’inyuma dukoreshwa cyane turimo urwego rwa 4.8, urwego rwa 8.8, urwego rwa 10.9, na 12.9. Nanone twitwa hexagon socket screws, kandi twitwa hexagon socket bolts. Umutwe ni umutwe wa hexagonal cyangwa umutwe wa cylindrical.

2. Ibikoresho
Icyuma cya karuboni n'icyuma kitagira umwanda.
Udupira tw’umutwe twa hex socket tw’icyuma cya karuboni dufite imiterere yo gukomera cyane no kugabanuka, kandi ni udupira duhendutse kandi dukoreshwa mu buryo bufatika. Dukoreshwa ahantu hamwe na hamwe, nko mu bikoresho byo gupima bike, ibikoresho bya buri munsi, ibikoresho byo mu nzu, inyubako z’ibiti, amagare, moto, nibindi.
Ibyuma bitagira umugese bifite imiterere yo kudashonga, kudashonga ubushyuhe bwinshi no gukomera neza, kandi bikunze gukoreshwa mu gukora vis n'imbuto zikenerwa cyane. Svis z'ibyuma bitagira umugese zikoreshwa cyane mu guhuza ibikoresho mu nganda zikora imiti, ibiribwa n'izindi nganda, ndetse no mu bikoresho bya chimique, ibikoresho by'ikoranabuhanga n'ahandi. Kubera ubushobozi bwayo bukomeye bwo kurwanya oxidation no kurwanya ingese, ntabwo byoroshye kuyingiza cyangwa kuyingiza bitewe n'ibidukikije, bityo ikaba ishobora kwimenyereza ibidukikije bikomeye.

3. Ibisobanuro n'ubwoko

Umubare usanzwe w'ibice by'umutwe bifite umutwe wa hexagonal ni GB70-1985. Hari ingano n'ibipimo byinshi. Ibipimo n'ibipimo bikunze gukoreshwa ni 3 * 8, 3 * 10, 3 * 12, 3 * 16, 3 * 20, 3 * 25, 3 * 30, 3 * 45, 4 * 8, 4 * 10, 4 * 12, 4 * 16, 4 * 20, 4 * 25, 4 * 30, 4 * 35, 4 * 45, 5 * 10, 5 * 12 , 5 * 16, 5 * 20, 5 * 25, 6 * 12, 6 * 14, 6 * 16, 6 * 25, 8 * 14, 8 * 16, 8 * 20, 8 * 25, 8 * 30, 8 * 35, 8 * 40, n'ibindi.

4. Ubukomere
Udupira two mu bwoko bwa hexagon dushyirwa mu byiciro hakurikijwe ubukana bw'insinga yo mu bwoko bwa screw, imbaraga zo gukurura, imbaraga zo gutanga umusaruro, nibindi. Ibikoresho bitandukanye bisaba urwego rutandukanye rw'udupira two mu bwoko bwa hexagon kugira ngo bihuze natwo. Udupira two mu bwoko bwa hexagon twose dufite urwego rukurikira:
Udupira tw’umutwe wa hexagon tugabanyijemo udupira dusanzwe n’utw’imbaraga nyinshi bitewe n’urwego rwatwo. Udupira tw’umutwe wa hexagon dusanzwe twerekana urwego rwa 4.8, naho udupira tw’umutwe wa hexagon dukomeye cyane twerekana urwego rwa 8.8 cyangwa hejuru, harimo urwego rwa 10.9 na 12.9. Udupira tw’umutwe wa hexagon duto twa 12.9 muri rusange twerekana utubuto tw’umutwe w’igikombe cy’umukara wa hexagon washyizwemo amavuta.
Ingano z'imikorere y'imigozi ya hexagon socket ikoreshwa mu guhuza imiterere y'icyuma igabanyijemo ibice birenga 10, birimo 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, na 12.9. Muri byo, imigozi yo mu cyiciro cya 8.8 no hejuru yayo ikozwe mu cyuma gikozwe mu cyuma gikozwe mu cyuma gikozwe mu buryo bwa karuboni nke cyangwa icyuma gikozwe mu buryo bwa karuboni iciriritse. Nyuma yo gushyushya (kuzimya no gushyushya), muri rusange yitwa imigozi ikomeye cyane, naho ibindi muri rusange yitwa imigozi isanzwe. Ikimenyetso cy'imikorere y'imigozi kigizwe n'ibice bibiri by'imibare, bigaragaza agaciro k'imbaraga zo gukurura n'igipimo cy'imbaraga z'umusaruro w'ibikoresho bya bolt.
