Product Overview
4 x 50mm Multipurpose Countersunk Pozi Screws designed for posts, beams, and timber joints.
Manufactured from hardened steel with a corrosion-resistant coating, they provide reliable performance across timber, plastics, and composite surfaces.

The medium-thread pattern provides strong engagement across wood-based materials.
