Хороший крепеж. Соответствуют стандарту, геометрия в норме. Покупал частичную резьбу, всё подошло четко.

Обычные болты, для бытовых нужд самое то. Класс прочности 4.8 не самый высокий, но для мебели и легких перегородок хватает за глаза.

Брал для сборки теплицы, цинк норм, не облезает. Резьба чистая, закручиваются легко. За свои деньги топ.
