This 50-pack of premium fasteners is specifically designed for securing the SUNGLAZE base profile to timber structures, particularly in environments where standard coatings would fail.

In coastal regions or areas with high humidity and industrial pollution, atmospheric salts and moisture can rapidly corrode standard zinc-plated or galvanised screws. These fixings are manufactured from High-Grade Stainless Steel, providing inherent resistance to rust and tea-staining. The “Pan Head” design offers a flat underside and a low-profile rounded top, which provides a significant clamping surface area to hold the aluminium SUNGLAZE base firmly against the timber rafter without distorting the metal.

At 38mm in length, these screws provide the optimal embedment depth into timber purlins or rafters. This ensures maximum pull-out resistance—a critical factor for roofing systems subject to wind uplift—while the 10-gauge thickness offers the shear strength necessary for structural glazing applications.

Key Features and Benefits

Superior Corrosion Resistance: Grade-A stainless steel construction makes these ideal for seaside properties and “highly corrosive” environments.
Specialist Pan Head Profile: Distributes pressure evenly across the aluminium base for a secure, flush fit.
Timber-Optimised Thread: Deep-cut threads ensure a permanent, vibration-resistant grip in both softwoods and hardwoods.
Chemical Compatibility: Stainless steel prevents the galvanic corrosion that can occur when dissimilar metals (like aluminium and low-grade steel) meet in damp conditions.
Aesthetic Longevity: Unlike coated screws, these will not produce unsightly rust streaks on your timber rafters or aluminium profiles over time.
