Ịmara ọkwa nke fastener na-enye ozi gbasara akụrụngwa ya, oke ike siri ike, ihe eji arụ ọrụ eletrik, yana ma ọ na-agbaso ụkpụrụ inch ma ọ bụ metric.

Ọmụmaatụ nke SAE J429 Ọkwa 2, Ọkwa 5 na Ọkwa 8

Society of Automotive Engineers (SAE) ehiwela ọkọlọtọ SAE J429 maka Mechanical and Material Requirements for Mechanical Fasteners. Ọkọlọtọ a na-ekwupụta akụrụngwa na akụrụngwa maka bolts inch, skru,studs, sems, naU-bolt, na-ekpuchi akụkụ ruo 1-½" na dayameta.
