How to Choose
- Screw type and thread for the board material
- Head type and drive (Pozi, Torx, hex socket)
- Length and diameter for the joint
- Board material: MDF, particle board, or plywood
- Pre-drilling and pilot-hole requirement
- Pull-out resistance and joint strength
- Bulk packaging and count per carton
Material Options
Hardened carbon steel with zinc plating is standard; stainless suits damp or outdoor-adjacent furniture. Thread geometry is tuned for chipboard and MDF holding power.
Finish Options
Zinc-plated (clear or yellow) is the default for corrosion resistance; black and nickel match exposed assembly screws.

Installation Notes
Pre-drill the recommended pilot in MDF and particle board to prevent splitting, then drive to flush without over-torquing. Use the correct bit to avoid cam-out on high-volume lines.
