The standard Length of this product is 29 mm and this product is less than 20 mm
the quality is as I expected it to be and the length was off my a couple of millimeters but it does the job that I bought it for. The hardness of the material is just right to hold the screw tighly in place and malleable enough to allow manually turning the screw without exerting too much effort.
The product is of excellent quality! Thank you seller!
item is of good quality and as described. recommended seller.
