Product Overview
Fermacell Screws with a 3.9mm diameter and 30mm length, supplied in boxes of 1000. These high-performance self-drilling screws are designed specifically for fixing Fermacell Gypsum Fibre Boards to timber or metal subframes.
Manufactured from hardened steel with a corrosion-resistant phosphate coating, they provide secure and durable fastening without the need for pre-drilling. The fine-thread design ensures high pull-out strength, tight board contact, and clean countersinking without surface damage.
The 30mm length is suited to single-layer board fixing in standard wall and ceiling systems.
