Review on Simpson SPS25344 KT Storm 🌀 Panel Screws: Unmatched Durability and Performance by Ryan Lawson

Bought two sets, the first set is 2 unthreaded screws for wing nuts. When ordering a second time, only 1/3 of the screws will fit in the drill and will need to be filed to fit. That's the price of Chinese quality control shops. I only buy from China when there is no other choice and I really appreciate the tariff war that keeps non-Chinese markets competitive, especially quality control in US manufacturing. IF YOU BUY them, consider the installation time as attaching these heads to the driver is time consuming and tedious; Nothing you want to do with a CAT 4 hurricane in a 24-48 hour drive.
