Review: ⭐️⭐️⭐️⭐️⭐️ Excellent Value and Solid Quality - These NIDAYE 1/4"-20 coupling nuts are exactly what I needed for my project. The threading is clean and consistent, and they fit perfectly with standard 1/4"-20 rods and bolts without any issues. The hex shape makes them easy to tighten, and they feel durable and well-made—not flimsy or weak. The 50-pack is a great value and gives you plenty of nuts for multiple uses. If you’re looking for reliable, well-threaded coupling nuts for DIY or professional use, these are a great choice. Highly recommend!
Review: A pleasure to use. - These coupling nuts worked perfectly. Seems to be very well made and the threads were good. I had no trouble with threading these onto the carriage bolts that I was using them on. I tack welded a wing nut on one end to make them work as an extended fastener to reach into a metal channel that secured the carriage bolts. The quality of the thread taps and plating were great, not one issue with any of them.
