Fasteners and Hardware — FAQ
How much weight can drywall actually hold?
Hollow drywall holds 5-10 pounds with standard nails. Use hollow-wall anchors for 20-50 pounds. Always mount heavy items directly into studs, which support 80+ pounds. Never exceed rated capacity without reinforcement.
What's the best hanger for plaster walls?
Plaster requires hardened steel nails or screw-in anchors to prevent crumbling. Avoid standard picture nails. Look for hooks specifically labeled 'for plaster' with sharp, tempered points that penetrate without shattering the surface.
Do I really need a stud finder?
For items under 20 pounds, no. For 20-50 pounds, it's recommended. For anything over 50 pounds, it's mandatory. Stud finders also prevent drilling into electrical wires and plumbing—a critical safety step.
Can I hang pictures without making holes?
Yes, for frames under 40 pounds. Use claw-style hangers that grip drywall without nails, or adhesive strips for pieces under 5 pounds. Both remove cleanly for renters. Test adhesion before trusting valuable artwork.
Sawtooth vs wire hanger: which is better?
Sawtooth works for frames under 10 pounds with center mounting. Wire hangers distribute weight across two points, preventing tilt in frames over 10 pounds or wider than 24 inches. Wire is superior for stability.
Are picture hangers reusable?
Metal hooks can be reused if they remain straight and the wall material is similar. Never reuse bent hooks. Nails should always be replaced. Claw hangers maintain effectiveness through multiple uses if undamaged.
