Installation Recommendations

• Drive trim screws at approximately half speed for improved control.
• Use a driver drill with adjustable torque settings or a driver bit equipped with a depth stop to help prevent over-driving.
• To reduce the risk of over-driving fasteners and extend drive bit life, an impact driver is not recommended.
• Pilot holes are generally only necessary when required by the building material manufacturer. Always consult the manufacturer's installation recommendations before fastening.
