Reattaching the locator assembly will not change the depth setting. Driving Drywall Screws For Screwdrivers Rated up to 4300 RPM Standard drywall screws are generally designed for attaching drywall to wood studs and 26 through 20-gauge steel studs. MILWAUKEE Screwdrivers are ideal for driving these types of drywall screws. The depth setting is very important. Refer to the guide below for the correct depth setting. Driving Decking Screws For Screwdrivers with Depth Locators Rated up to 2900 RPM Standard decking screws are generally designed for attaching wood to wood studs. MILWAUKEE Screwdrivers are ideal for driving these types of decking screws. The depth setting is very important. Refer to the guide below for the correct depth setting. Correct.

WARNING To reduce the risk of injury, always unplug the tool before performing any maintenance. Never disassemble the tool. Driving Self-Drilling Screws into Contact a MILWAUKEE service facility for ALL Cold-Formed Steel Framing repairs. For Adjustable Torque Screwdrivers Rated up to 2900 RPM Follow this procedure when working with light gauge sheet metal, 20 gauge and thicker. The screw may hesitate slightly when it finishes breaking through the first layer of material and starts to penetrate the sheet metal. This is normal. Keep firm pressure on the tool until the screw is fully seated. Self-drilling and self-tapping screws drill, tap and fasten in one quick, easy motion without a separate drilling operation. Their unique design works in metal up to 1/2" thick, giving a strong, reliable hold. The drill point ensures rapid drilling and consistently low Maintaining Tools Keep your tool in good repair by adopting a regular maintenance program. Inspect your tool for issues such as undue noise, misalignment or binding of moving parts, breakage of parts, or any other condi- tion that may affect the tool operation.
