Knurled pins are great to use as a replacement because they are heavy duty and sturdier than cotter pins which can keep falling out. Using these heavier solid pins in place of cotter pins will help to extend the life of your watch band making it more secure. You can also use knurled link pins to replace screw type link pins once the threaded pin hole has become stripped, allowing you to continue to use your favorite watch band
