4-Inch Metal Screw-In Shower Drain Strainer Cover Kit - Complete Kit with Machine & Self-Tapping Screws

4-Inch Metal Screw-In Shower Drain Strainer Cover Kit

Key Features

• 4-inch diameter circular screw-in drain cover designed for standard residential shower pans and floor drains.
• Manufactured from heavy-gauge stamped metal with a corrosion-resistant finish to withstand continuous water flow and standard bathroom cleaning agents.
• Punched grid pattern engineered to optimize water drainage speed while effectively catching hair and large debris to prevent pipe clogs.
• Complete installation kit includes both standard machine screws and self-tapping screws to accommodate various drain shoe materials.

Replaces / Cross-Reference Part Numbers

• Universal 4-Inch Round Shower Strainer
• Standard 4" Screw-In Drain Grate
• 4-1/4" Drain Cover Trim Set

Compatibility & Fitment

• Compatible with standard US residential shower drain bodies requiring a flat, screw-mount configuration.
• Fits major rough plumbing brands including Oatey, Sioux Chief, and ProFlo featuring standard center-to-center screw hole spacing (typically 2-7/8 inches to 3 inches).
• Suitable for direct installation onto PVC, ABS, or cast-iron drain collars using the appropriately provided screw type.

When to Replace

• The existing metal drain grate is heavily tarnished, rusted, or structurally compromised by corrosion.
• The cover is dented, bent, or has sharp edges, creating a physical cut hazard for bare feet.
• Original mounting screws are stripped, broken, or missing, causing the strainer assembly to sit loosely, shift, or rattle.
• Updating bathroom hardware finishes during a shower stall remodel or routine cosmetic maintenance.

Installation Tips

• Thoroughly clean the drain collar opening, removing any built-up soap scum, hair, or hard water deposits prior to seating the new grate.
• Align the new strainer cover over the drain body to verify the center-to-center screw spacing matches perfectly.
• Select the correct fasteners: use the flat-tipped machine screws for threaded metal drain bodies, or the sharp self-tapping screws for unthreaded plastic (PVC/ABS) drain bodies.
• Hand-tighten the screws evenly using a standard Phillips-head or flathead screwdriver; avoid using power drills to prevent stripping the threads or warping the metal grate.
