Drywall Screw Makita DFR551RTJ 3.9mm PH2 45mm for drywall fastening

Drywall Screw Makita DFR551RTJ 3.9mm PH2 45mm for drywall fastening is a fastener designed for installing gypsum plasterboard to timber and light framing. The screw features a 3.9 mm shank diameter, PH2 recessed drive and a 45 mm length, making it suitable for common drywall thicknesses and standard stud depths. It is compatible with screwdrivers and collated screwdrivers that accept PH2 bits and is intended to provide consistent engagement and reliable holding for interior drywall assemblies.

Advantages

The screw’s 3.9 mm diameter and 45 mm length deliver a balance of penetration and pull-out resistance for typical gypsum board applications. The PH2 drive recess ensures secure bit engagement, reducing cam-out and enabling efficient fastening with powered drivers. The fastener’s thread and point geometry are optimized for smooth entry into drywall and timber framing, helping to speed up installation while maintaining a firm hold.

Suitable for

• Fastening gypsum plasterboard to wooden studs and light timber framing
• Interior drywall installations in residential and commercial buildings
• Use with screwdrivers or collated screwdrivers that accept PH2 bits
• Repairing or replacing drywall panels and trimming edges

Key specifications

• Screw diameter: 3.9 mm
• Drive type: PH2 (Phillips #2) recessed drive
• Length: 45 mm
• Intended substrates: gypsum plasterboard and timber framing
• Application: interior drywall fastening

How to use

Select a PH2 driver bit and set the torque on your cordless or collated screwdriver to a level appropriate for drywall and wood to avoid overdriving. Position the drywall sheet against the framing, align the screw over the stud location, and drive the screw until the head is slightly below or flush with the paper surface of the board without tearing it. For collated systems, ensure the collated strip and feed mechanism align with the driver and that screws are loaded according to the tool manufacturer’s instructions.

Usage recommendations

Use the screws for interior applications only and match screw length to board and framing thickness. Adjust driver torque to prevent crushing the gypsum paper or countersinking too deep. Store fasteners in a dry environment to avoid corrosion if they are not pre-coated for exterior use.
