The Simpson Quik Drive PRO250 Subfloor Attachment is an auto-feed screw driving attachment engineered for subfloor fastening to wood or steel. Built on Simpson's philosophy of matching every system component to real-world installation workflows, this attachment converts repetitive fastening tasks into a faster, more controlled process. Whether you are securing subfloor panels on a wood frame or driving into steel, the PRO250 attachment delivers consistent results across demanding jobsite conditions.

Key Features

• Available alone or as part of the PRO250 subfloor system - gives you the flexibility to add only what you need, whether you are outfitting a new setup or upgrading existing equipment.
• Expanded depth settings for high-density flooring materials - lets installers dial in precise fastener depth across a wider range of subfloor material densities, reducing the risk of over-driving or under-setting screws.
• Reversible replaceable non-skid teeth attachment - extends the working life of the attachment by allowing the teeth to be flipped and replaced, keeping grip performance consistent over time without replacing the full unit.
• Uniform toenailing and countersink on slick surfaces - the non-skid teeth maintain positioning on smooth or slippery substrates, so every fastening point lands at a consistent angle and depth.

Why This Product

• Engineered for subfloor efficiency - Simpson designed this attachment specifically for subfloor-to-wood and subfloor-to-steel applications, meaning the geometry, depth settings, and grip features all serve the demands of flooring installation rather than general-purpose use.
• Adaptable to high-density materials - the expanded depth settings address a common limitation of standard auto-feed attachments, making this a practical choice for installers working with denser or engineered subfloor products where precise countersink control matters most.
• Reliable grip on challenging surfaces - the reversible replaceable non-skid teeth keep the attachment stable on slick substrates, protecting the consistency of each fastening point and reducing rework caused by slipping or misaligned drives.
• Broad fastener compatibility across Simpson collated screws - supports a wide range of Simpson collated screw series in sizes from 1 1/2 in. to 2 1/2 in., giving crews the versatility to handle varied subfloor fastening requirements without switching attachments.
