Unique-Bargains 50pcs M8 12x15mm Cross Dowel Slotted Furniture Nut

50-piece M8 cross-dowel set

This pack contains fifty metal cross-dowel nuts sized M8 by 12 mm by 15 mm. They are intended for furniture assembly where a barrel bolt must join two panels at right angles. The slotted end accepts a standard screwdriver for quick tightening. Buyers who need a different thread diameter or a larger quantity per box will need another product.

Slotted-drive limits for flat-pack joints

The single screwdriver slot transmits torque only while the bit stays seated; it can cam out under high force or if the slot walls deform. Cross-dowel geometry also requires a precise cross-drilled hole in the mating panel, so misaligned factory holes reduce clamping pressure. Applications that demand hex or Torx drive, or that involve structural loads beyond typical flat-pack furniture, exceed what this design can reliably deliver.

Simple installation with alignment care

Each nut drops into its pre-drilled hole and is turned with a flat-blade screwdriver until the bolt draws the joint tight. The main difficulty is keeping the cross-hole and bolt hole perfectly perpendicular; even a small angular error prevents the dowel from engaging the threads. Debris in the slot or oversize cross-holes are the most common reasons a nut spins without gripping.
