Enwere ọtụtụ aha dị iche iche maka mpụta hexagonal mpụta, dịka ọmụmaatụ, enwere ike ịkpọ ya mpụta hexagonal mpụta, dịka ọmụmaatụ, enwere ike ịkpọ ya mpụta hexagonal mpụta. Enwere ike ịkpọ ya ihe mkpuchi hexagonal mpụta. Ihe a niile pụtara otu ihe. Ọ bụ naanị na àgwà onwe onye dị iche. Mgbe ọgwụgwọ elu galvanizing na-ekpo ọkụ gasịrị, a na-enweta mmetụta mgbochi corrosion.
1. A na-ekewa bolts nkịtị na a, b na c. Abụọ ndị mbụ bụ bolts a nụchara anụcha, nke a na-ejikarị eme ihe. N'ikwu okwu n'ozuzu, bolts nkịtị na-ezo aka na klas C nkịtị bolts.
2. Klas C nkịtị bolts na-ejikarị na ụfọdụ nwa oge njikọ na njikọ chọrọ disassembly. Ihe mgbochi a na-ejikarị eme ihe n'ihe owuwu ụlọ bụ M16, M20 na M24. Ụfọdụ bolts crude na igwe ụlọ ọrụ nwere ike inwe nnukwu dayameta na ebumnuche pụrụ iche.

Ọkwa arụmọrụ nke bolt hexagon dị mpụta nwere ọnụọgụ abụọ, nke na-anọchi anya uru ike tensile ọnụ na ntinye ike nke ngwongwo bolt.
Dịka ọmụmaatụ, bolts nwere ọkwa arụmọrụ 4.6 pụtara:
a. Ihe Bolt: ike tensile ọnụ ruru 400MPa;
b. Ọnụ ego nke ihe mkpuchi bụ 0,6;
c. Ike ntinye aha nke ihe bolt ruru 400 × 0.6 = 240mpa ọkwa.
Igwe ike dị elu na ọkwa arụmọrụ nke 10.9 nwere ike izute ihe ndị a chọrọ mgbe ọgwụgwọ okpomọkụ gasịrị:
a. Ihe Bolt, ike tensile ọnụ ọnụ ruo 1000MPa;
b. Ike ntinye aha nke ihe bolt ruru 1000 × 0.9 = 900MPa ọkwa.
