I need to replace a number of screws on my 6s. There are many kits which include the replacement screws but it appears they are not identified as to size. Are there any kits available with the screws labeled.
Never seen such kits for sale anywhere. However, if you have a caliper you should be able to get the right screws in place by following the board replacement guide that shows and lists one by one size and shape of all screws involved: iPhone 6s Logic Board Replacement
