The standard sizing fits snugly into pre-drilled holes without wobbling.

Choosing Between Them
For your next shelving project, I recommend choosing the 104-piece four-style kit because its mixed assortment guarantees you will find the exact shape for any furniture repair job, though cheap bulk metal hardware can occasionally suffer from uneven plating finishes. Match the 1/4-inch pins to your traditional wood bookcases, or select the 5mm metric pegs for modern European cabinetry.
Keep in mind that bulk hardware packages often mix different pin shapes into one bag, so you will need to sort through the pieces before starting your installation. Cheap metal alloys can sometimes lack uniformity, making it wise to inspect each pin for consistent load bearing before placing valuable items on your shelves.
