Качественный крепеж, соответствуют стандарту. Использовал в конструкции навеса, всё держит мертво. Доставили быстро.
Норм болты, за свои деньги отличный вариант. Чернение выглядит прилично, хотя в агрессивной среде лучше что-то помощнее, но для гаража супер.
Брал для сборки станины станка. Прочности 8.8 за глаза хватает, резьба прошла легко, покрытие ровное. Рекомендую!
