The LCN 4040XP-TBSRT is a self-reaming, thread-forming (TB/SRT) screw pack designed for use with the LCN 4040XP series surface-mounted door closers. These self-reaming fasteners are engineered to cut their own threads during installation, giving you a secure, reliable hold when mounting the closer body or arm to the door and frame. Made to match the durability standards of the heavy-duty 4040XP platform, this hardware pack is a practical replacement or supplemental option for installers who need dependable mounting screws. Whether you are completing a new installation or replacing missing fasteners on an existing closer, this pack keeps your 4040XP closer securely fastened.
