Installing fixtures, cabinets, or trim to tile requires the right screws, anchors, and techniques to prevent cracking and ensure durable holds. This guide explains the best screws for tile types, how to drill and anchor properly, corrosion resistance, and recommended products for common home projects. It focuses on practical advice for ceramic, porcelain, and natural stone tiles used in U.S. homes.
| Tile Type | Recommended Screw Type | Anchor/Prep | Typical Use |
|---|---|---|---|
| Ceramic Glazed | Stainless Steel Or Zinc-Plated Wood/Sheet Metal Screws | Plastic Anchor Or Toggle With Pilot Hole | Light Fixtures, Shelves, Electrical Boxes |
| Porcelain | Harder Fasteners Like Stainless Steel Or Self-Tapping Concrete Screws | Carbide Tile Bit Pilot Hole, Nylon Or Sleeve Anchors | Handrails, Heavy TV Mounts With Backer |
| Natural Stone (Marble, Granite) | Stainless Steel Or Brass Screws With Low-Torque Anchors | Careful Pilot Hole, Epoxy Or Sleeve Anchors | Vanity Mounts, Decorative Hardware |
Why Choosing The Right Screw For Tile Matters
Tile is brittle and unforgiving: a wrong screw or drilling method can crack the tile or lead to poor holding power. Selecting the correct screw material, size, and anchor type maximizes strength while minimizing risk of damage. The wrong combination causes cosmetic breaks, structural failure, or corrosion in wet areas.

Types Of Screws Suitable For Tile
Common screw types used with tile include wood screws, sheet metal screws, masonry screws, self-tapping concrete screws, and machine screws used with anchors. Stainless steel screws are preferred for moisture-prone areas like bathrooms and kitchens due to corrosion resistance.
Stainless Steel Screws
Stainless steel screws (304 or 316 grades) resist rust and staining, important near water or salt exposure. 316 stainless is superior in coastal or very humid environments, but 304 is adequate for most interior uses.
Zinc-Plated And Coated Screws
Zinc-plated screws are economical and commonly used in dry interior spaces. They should be avoided in wet environments where corrosion could weaken the fastener or stain the tile.
Masonry And Concrete Screws
Masonry screws (e.g., Tapcon) are hardened, thread-cutting screws designed to bite into concrete or brick. With proper pilot holes, masonry screws provide excellent hold when tile sits over a concrete substrate.
Anchors And Fastening Systems For Tile
Screws alone rarely provide reliable holding in tile. Anchors distribute load and protect the tile from direct stress. Select anchors based on substrate: drywall, cement backer board, concrete slab, or wood studs behind tile.
Plastic Expansion Anchors
Plastic anchors work well for light fixtures and small loads in drywall or cement backer board when a stud is not accessible. They are inexpensive but limited to light-to-moderate loads.

Molly And Toggle Bolts
Molly and toggle anchors expand behind the substrate, offering strong support for medium to heavy items when the tile sits over hollow cavities. Toggle bolts are especially useful for heavy shelves or towel racks on tile over drywall.
Sleeve Anchors And Wedge Anchors
Sleeve and wedge anchors are designed for solid concrete or masonry substrates. They require a proper hole size and depth but provide robust anchoring for heavy loads.
Epoxy Anchors
Epoxy adhesives used with threaded rods or screws create near-permanent secure connections in stone and concrete. Epoxy anchoring is recommended for critical or heavy structural attachments where vibration or shear is a concern.
Drilling Tile: Bits, Speed, And Technique
Accurate drilling prevents tile cracking. Use carbide-tipped or diamond-tipped bits for hard tiles and follow low speed with light pressure. Always start with a center punch or masking tape to prevent bit wandering, and cool the bit if necessary to avoid overheating.
Bit Types
- Carbide-Tipped Masonry Bits: Good for ceramic and some porcelain; affordable.
- Diamond-Tipped Bits: Best for dense porcelain and natural stone; longer life and cleaner holes.
- Glass And Tile Bits With Tungsten Tips: Suitable for thin or delicate tiles to reduce cracking.
Drilling Tips
- Mark the location and apply masking tape to reduce slippage.
- Use a center punch or nail to make a shallow dimple if tile thickness permits.
- Start at low RPM and apply gentle, steady pressure; stop periodically to clear debris.
- Drill through the tile first, then switch to a masonry bit if entering substrate like concrete.
Best Screws For Specific Tile Scenarios
Different projects demand different fasteners. Below are recommended screw and anchor pairings for typical household tile installations. Choosing the correct pairing reduces failure risk and preserves tile appearance.
Mounting Light Fixtures Or TP Holders On Ceramic Tile
Use #8 or #10 stainless steel wood/sheet-metal screws with plastic anchors or toggles if not anchored to stud. Use a carbide bit to pilot through the tile and standard masonry bit for backer board.
Attaching Cabinets Or Heavy Shelving Over Tile
Whenever possible, fasten to studs through the tile using long stainless screws and a washer. If studs are unreachable, use toggle bolts or epoxy anchors rated for the load. For heavy loads, install a plywood blocking behind tile during remodels for the strongest option.
Mounting TV Brackets On Tile Over Concrete Or Brick
Use hardened masonry screws (Tapcon) or wedge anchors sized to the bracket specification and substrate depth. Diamond pilot holes are preferred for porcelain and natural stone tiles to avoid damage.

Outdoor Tile Projects And Exterior Fixtures
Choose 316 stainless steel screws and anchors designed for exterior masonry to resist corrosion. Galvanized or epoxy-coated fasteners may be acceptable for moderate exposure, but 316 stainless offers the best long-term protection.
Corrosion Resistance And Finish Considerations
Appearance and longevity matter for visible fixtures. Stainless steel offers the best corrosion resistance and is available in polished finishes. For painted or brass hardware, choose screws that match the finish or use decorative caps to conceal fasteners.
How To Size Screws For Tile Installations
Screw length should penetrate the substrate or anchor sufficiently without bottoming out in the tile. A common approach is: tile thickness + backing + 1 to 1.5 inches into stud or substrate. Proper length ensures full engagement and load distribution.
Common Mistakes And How To Avoid Them
Frequent errors include drilling too fast, skipping pilot holes, using the wrong anchor, and overtightening screws. Overtightening is a leading cause of tile cracking and stripped anchors.
Avoiding Cracked Tiles
Use the correct bit, go slow, support the tile edge when possible, and stop as soon as the bit penetrates the tile glaze before switching bits for the substrate. Do not apply excessive torque; finish tightening by hand with a screwdriver.
Preventing Loose Fixtures
Confirm anchor ratings match the expected load and choose mechanical anchors for heavy or dynamic loads. Regularly inspect and re-torque exterior or high-use attachments as part of home maintenance.
Product Recommendations And Where To Use Them
Several brands produce reliable screws and anchors suited to tile projects. Below are widely available categories and typical use cases. Recommendations balance corrosion resistance, strength, and cost-effectiveness.
