Flat bolts are typically installed in horizontal positions and can also be used in vertical positions at the bottom of doors, we do not recommend fitting to the top of doors as aggressive rattling of the door can allow the bolt to disengage.
This door bolt is supplied with colour matched raised countersunk slot headed screws for the bolt and standard keep, and Pozidrive countersunk screws for the flat keeps.
PRO TIP: Use a spare hardened steel Pozidrive screws to ensure the pilot holes are the correct size to prevent rounding off the fixing screw heads (especially important in oak and other hardwood doors).
