Description
High-strength hexagonal bolts class 8.8 are designed for creating reliable and durable connections in critical structures. Made from high-quality 45# carbon steel, these fasteners offer exceptional resistance to mechanical stress and deformation.
The bolts feature a galvanized surface treatment that provides effective protection against corrosion and oxidation. This makes them an ideal choice for use in high-humidity environments and aggressive atmospheres, significantly extending the service life of the assembly.
Manufactured according to the GB/T 5782-2016 standard, these fasteners ensure precise dimensions and consistent technical performance. They are widely utilized in the construction industry, bridge building, rail transit equipment manufacturing, and general hardware applications.

Норм крепеж. По геометрии всё четко, в пазы зашли без проблем. Доставили быстро.

Отличные болты, взял для сборки навеса. Резьба чистая, закручиваются легко, цинк лежит ровно. Для класса 8.8 самое то, реально крепкие.
