I am usinthese anchors to secure an access panel, will I be able to remove nuts after installing?
Thank you for reaching out to us, Ray. The advantage of the wedge anchors is the ability to remove the nut and washer in order to remove the fixture and replace as needed. The threads of the anchor will always remain exposed beyond the surface to achieve that.
