LonlyEagle Clear Self-Locking Shelf Support Pegs, 6 mm, 20 Pieces

Twenty push-fit supports for adjustable shelving inside cabinets, wardrobes and bookcases. Each peg snaps into a drilled hole and locks itself, with a molded lip that grips the underside of the board instead of merely propping it up.

• Quantity: 20 pegs.
• Pin diameter 6 mm (0.24 inches), measured across the ridge; the pin projects 6.6 mm.
• Board thickness: designed around 20 mm (3/4 inch) shelving.
• Drill note: bore the hole a shade under 6 mm so the ridge bites; an oversized hole lets the peg spin loose.
• Hand fitting only - no screws, no adhesive, and nothing left behind when a shelf is repositioned.
• Transparent plastic keeps the hardware visually quiet against light and dark cabinet interiors.

Each peg carries one corner of the board, so fit four per shelf and check that all four holes sit level before loading.
