Отзыв о 4-Pack 1,5-дюймовые ролики с поворотным стержнем - грузоподъемность 330 фунтов, не оставляющие следов полиуретановые колеса и 3/8 "- 16 X 1" резьбовые стержни с гайками для тележек для мебельных тележек. от Anthony Arcos

Got these to turn an older front loader washing machine base into mobile platform. Though not pictured, they include a low profile wrench which helps. Some have commented that the "jam" nut is too large and not usable. IMO the nut is for installation through a non-tapped hole such as on a metal plate. All in all a great value for the money and exactly what I needed.
