About the Conical Expansion Plug (Ribbed)
A conical plug expands from the bottom up: as the screw is driven, the tapered body is forced outward and the deep ribs bite into the hole wall along the whole length. That even expansion is what keeps a small plug holding in soft brick, where a straight-sided plug would simply spin.
Typical applications
- Brick and masonry — Curtain rails, pictures, shelving and general household fixing.
- Concrete — Light and medium loads where a metal anchor is overkill.
- Retail and DIY packs — Sold in small quantities with screws for hardware shops.
How to choose the right specification
- Length by substrate — 22–25 mm for thin plaster and tile, 32–38 mm for brick and block where more embedment is needed.
- Rib depth — Deeper ribs grip better in soft brick; the standard rib suits concrete and hard masonry.
- Material — PP for general use, nylon for higher strength and better temperature resistance.
