Does this cover a 1/4-20 screw

Thanks for your patience during this very busy season. I'm researching this with one of my senior colleagues as we speak, and we'll get back to you as soon as we can with more information. Thanks again for bearing with us. 

Hello there. These push on screw caps are used on smaller screw head like a #8 screw. However if you are using a flat #1/4- 20 screw, these caps will still cover the screw head, but you will need to use some type of adhesive to keep it in place, as it will not lock into the larger head.
