A Grade 5 hex nut features medium strength, while Grade 8.8 is the strongest of the two ranges. According to the Society of Automotive Engineers (SAE), the term “grade” refers to a hex nut’s strength. The lowest is Grade 2, while Grade 5 nuts are of medium strength. Meanwhile, Grade 8 hex nuts are of high strength.
The cost also goes together with the Grade. To distinguish between the grades of these fasteners
, look for unique markings on their surfaces. More so, you should replace a hex nut with another of a similar or higher class. Both grades feature a six-sided bolt that is internally threaded
Grade 8.8 hex nuts are, therefore, more hardened than Grade 5 hex nuts. They are used in automotive suspensions and other demanding applications. Technically, a Grade 5 hex nut deforms faster than its Grade 8.8 counterpart. In engineering terms, this is referred to as the plastic range.
