Screw head diameter

Hi, Is there a list of screw head diameter anywhere? As I need screws to fit inside a wall fixing
Asked by: MPhys
Hi MPhys, There are tables of screw head diameters on the internet. However, they can vary from type to type and brand to brand. For screws like this one, the rule of thumb is the head diameter will be about 2 1/4 times the diameter of the shank / thread. Thank you for using Q&A. PB

painting over question

Hi. I note these are described as 'wax coated' so can you advise if they are suitable for priming & painting over as I don't want the paint blowing off in a few weeks or months!
Asked by: tottenhouse
Hello Tottenhouse, The screws, if left unaltered, will not be suitable to be painted over. You would be required to file down the head slightly to remove the wax coating, however doing this will make the screw more prone to rust. Thank you for using Q&A. (LM).
