Review on 🔒 50PCS Locking Button Fastener by Longdex by Corey Burgess

These 13mm plugs were purchased to cover 1/2" holes. Delivery was fast, looks good. What fared poorly were the inconsistent crown diameters (measured at the end of the piston where it enters the bore). According to the description, it should be 12.7 mm. The ones I received ranged from 12.65mm to 13.75mm with everything in between.
