Product Description

PRODUCT PARAMETER

Fiberboard Screws

Fiberboard screws are specialized fasteners engineered for medium-density fiberboard (MDF), particleboard, and other fiber-based panels. Their sharp self-tapping tips and fine threads minimize cracking by distributing pressure evenly, eliminating the need for pre-drilling in most cases .

Constructed from zinc-plated carbon steel (ideal for dry indoor use) or 304 stainless steel (for damp environments), they adhere to standards like DIN 7996 and ISO 15480, with sizes ranging from M3 to M8 and lengths 16–80mm . Many feature saw-tooth thread designs to enhance grip in low-density materials .

Key Applications:

Furniture Manufacturing: Secure MDF/particleboard components in wardrobes, desks, and cabinets without splitting .
Interior Trim Work: Install skirting boards, door casings, and decorative panels on walls.
DIY Projects: Assemble craft pieces, toy parts, or lightweight shelves using fiberboard.
Packaging: Reinforce fiberboard crates for stable, damage-free shipping.
