Fasteners and Hardware — FAQ
What's the difference between drywall screws and anchors?
Drywall screws fasten drywall panels directly to wood or metal studs. Anchors install into finished drywall to create a mounting point for hanging items like shelves or pictures. Use screws for installation, anchors for decoration.
What size screws should I use for 1/2-inch drywall?
Use 1-1/4-inch coarse-thread screws for single-layer 1/2-inch drywall on wood studs. For 5/8-inch firecode drywall, step up to 1-5/8-inch screws. Always ensure 5/8-inch penetration into the framing member.
Can I use drywall screws in concrete or brick?
No. Drywall screws lack the hardness and thread design for masonry. Use masonry-rated anchors like those in the Wensilon or KURUI kits, which include appropriate fasteners for concrete and brick applications.
How many screws do I need per 4x8 sheet of drywall?
Code requires screws every 12 inches on ceilings and 16 inches on walls. This equals 32-40 screws per 4x8 sheet. For high-traffic areas, add 4-6 screws along the vertical edges for extra holding power.
Fine thread vs coarse thread drywall screws?
Coarse-thread screws grip wood studs aggressively, preventing pull-out. Fine-thread screws work better for steel studs, as they thread cleanly without stripping. Match thread type to your framing material.
Why do my drywall screws keep breaking?
Breaking usually indicates low-quality steel or overdriving. High-hardness screws like the JEGONFRI kit resist shear forces better. Adjust drill clutch to prevent sinking heads too deep, which weakens the paper face and causes snaps.
