This 24 pack of screws is great for the heavy-duty Speedplay user. Great to have extra screws on hand to replace missing screws or screws with damaged heads. V.2 Cleat Fastening Screws are visually distinct from pre-V.2 cleat fastening screws. The V.2 Cleat fastening screws are not continuously threaded up to the head of the screw. Instead, the threads of the screw stop mid-way up the screw shaft and then have a small, unthreaded section of the shaft continuing to the screw head. These screws are pre-Loctited and should be tightened to a maximum of 2.5Nm/22 inch-pounds. It also to re-check the torque after the first few rides.
