Installation Guide
This section provides step-by-step instructions for installing your Hyper Tough deadbolt.
Tools Required
- Phillips Head Screwdriver
- Tape Measure
- Pencil
- Drill (with appropriate bits for wood/metal, if new installation)
- Chisel (if mortising is required)
Pre-Installation Check
- Ensure your door thickness is between 1-3/8" and 1-3/4".
- Verify the backset (distance from door edge to center of bore hole) is either 2-3/8" or 2-3/4". The latch mechanism is reversible to accommodate both.
Installation Steps
- Prepare the Door: If installing on a new door, use the provided template to mark and drill the necessary holes for the deadbolt and latch. For existing installations, remove the old hardware.
- Install the Latch Mechanism: Insert the deadbolt latch mechanism into the edge bore hole of the door. Ensure the "UP" arrow (if present) faces upwards. Secure it with the provided screws.
- Install the Exterior Cylinder: Insert the exterior deadbolt cylinder assembly through the larger bore hole on the door, ensuring the tailpiece aligns with the slot in the latch mechanism.
- Install the Interior Thumb-Turn: Place the interior thumb-turn assembly over the tailpiece, aligning the mounting posts with the holes in the door.
- Secure the Assemblies: Use the long mounting screws to connect the interior and exterior assemblies, tightening them evenly until snug. Do not overtighten.
- Install the Strike Plate: Close the door and mark the position where the deadbolt throw extends to the door frame. Chisel out a shallow recess for the strike plate and secure it with screws. Ensure the deadbolt extends smoothly into the strike plate.

Care and Maintenance
- Cleaning: Clean the deadbolt with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- Lubrication: Periodically apply a small amount of graphite lubricant or a silicone-based spray to the keyway and the latch mechanism to ensure smooth operation. Do not use oil-based lubricants as they can attract dust and grime.
- Inspection: Regularly check all screws for tightness and ensure the deadbolt operates smoothly without binding.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Deadbolt is stiff or hard to turn. | Lack of lubrication; misalignment; debris in mechanism. | Apply graphite lubricant to keyway and latch. Check for proper alignment of strike plate and latch. Clean any visible debris. |
| Key does not insert or turn smoothly. | Bent key; debris in keyway; worn cylinder. | Try a different key. Apply graphite lubricant to keyway. If problem persists, cylinder may need replacement. |
| Deadbolt does not fully extend or retract. | Misaligned strike plate; door/frame swelling; bent latch. | Adjust strike plate position. Check for door/frame issues. Inspect latch for damage. |
| Deadbolt rattles when door is closed. | Loose screws; worn components. | Tighten all mounting screws. If rattling persists, components may be worn and require replacement. |
