Mutu wa bolt ndi wozungulira wokhala ndi mabowo, malo ozungulira ndi osalala, kuyika kwa Eye Bolts kumakhala kosavuta, ndipo nthawi zambiri amagwiritsidwa ntchito pa nthawi yotsegulira ndi kusokoneza kapena kusonkhanitsa zida. 2.Mabowo a Maso amagwiritsidwa ntchito kwambiri mu: kutentha kochepa ndi ma valve othamanga, mapaipi oponderezedwa, makina opangira madzi, kubowola mafuta ndi zida zopangira, zida zamafuta ndi madera ena, nthawi zambiri pakuchotsa kapena zida monga mafakitale a valve, njinga zopindika, zoyenda zimagwiritsidwa ntchito, chifukwa kugwiritsidwa ntchito kwa Bolts kwamaso ndikosavuta komanso mwachangu, komanso kugwiritsa ntchito mafananidwe ofananirako, kugwirizanitsa ntchito zosiyanasiyana.

DIN 933 ndiye muyezo wamabawuti ammutu onse okhala ndi ulusi wa hexagon, imodzi mwazomangira zomwe zimagwiritsidwa ntchito kwambiri pomanga, makina, magalimoto ndi mafakitale. Bawutiyo imakhala ndi mutu wa hexagonal kuti muyike ma torque mosavuta ndi ma wrenchi, komanso kapangidwe ka ulusi wautali kuti akwaniritse zofunikira zomakanikira.
