Frequently Asked Questions
Are the screws included compatible with drywall or studs?
Most packs include both long and short screws intended for wood studs and shelf anchoring; for drywall-only installations you should use appropriate anchors or toggle bolts — the included screws are best when driven into studs or with separate anchors.
Will the powder coat prevent rust in a bathroom or covered porch?
Powder coat provides basic corrosion resistance suited to indoor bathrooms and covered porches, but it’s not as corrosion-resistant as stainless steel for constantly damp or salt-air environments. For long-term outdoor exposure, choose stainless hardware.
Do these brackets really support 100 lb per pair?
Manufacturers rate many of these 100 lb per pair under ideal conditions (properly mounted into studs and with evenly distributed load). Real-world capacity depends on installation quality, wall type, and shelf material; always plan conservatively.
