Our Drywall Screws (4.8 x 100mm) are professional-grade fixings designed for securing plasterboard to timber studwork. Featuring a sleek black phosphate coating for superior corrosion resistance and a bugle head design, these screws ensure a flush finish without tearing the paper surface of the board.
Extra-Long Reach: 100mm length is ideal for double-boarding or fixing through thick insulation layers.
Black Phosphate Finish: Provides enhanced lubrication for faster driving and excellent resistance to rust.
Bugle Head Design: Specially shaped to sink perfectly into the plasterboard, preventing surface damage.

Drywall screws of this length are specialized fixings used primarily in the construction of high-performance partitions and ceilings. While standard screws are usually 32mm or 42mm, the 100mm drywall screws are essential when fixing multiple layers of fire-rated or soundproof plasterboard (double-boarding) or when attaching boards through thick PIR insulation boards into the underlying timber rafters or studs.
The distinctive black finish on these drywall screws is a phosphate coating. This chemical treatment serves two critical purposes: first, it acts as a dry lubricant, allowing the screw to be driven at high speeds with less friction and heat buildup. Second, it provides a superior “key” for plaster and paint, while offering significantly better corrosion resistance than standard bright zinc screws when exposed to the moisture present in wet plastering processes.
At ECO HEAT SHOP, we provide fixings that ensure a professional-grade result. These drywall screws feature a sharp needle point for an immediate start without a pilot hole and a deep Phillips No. 2 drive to minimize cam-out. The bugle head is specifically engineered to depress the plasterboard surface just enough to allow for a smooth layer of joint filler or “skimming,” ensuring no screw heads are visible after the final decorate.

Usage Tip: When using 100mm drywall screws, ensure your drill/driver clutch is set correctly. The goal is to drive the bugle head slightly below the surface of the paper without breaking it. A broken paper surface significantly reduces the holding power of the screw.
