Shelf Pin

Shelf pins are small pegs inserted into pre-drilled holes to support adjustable shelves inside cabinets and bookcases. This simple hardware enables customizing storage heights as needs change. The standard 5mm pin system has become universal, though various pin styles exist. Metal pins outlast plastic; larger pins support heavier loads. Quality pins grip holes firmly without wobble.

Placement & Usage Tips

Drill pin holes in consistent patterns for shelf adjustability. Keep spare pins available for adding shelves later. Four pins per shelf provide stability.

💡 Pro Tip

When building bookcases, drill pin holes all the way up at consistent spacing—you cannot add holes later without removing shelves and contents.
