Masterdeck KH Color Stainless Steel Screws

Masterdeck KH Color are professional starter screws specifically designed for fastening solid composite decking boards to aluminium substructure profiles. Thanks to their specially engineered self-drilling point and thread designed for aluminium profiles with wall thicknesses of up to 3 mm, they provide fast, accurate, and reliable installation without the need to pre-drill the aluminium profile. The screws are manufactured from martensitic stainless steel SUS410 (AISI 410), offering exceptional hardness and tensile strength, making it an ideal material for self-drilling screws. Each screw is further protected with a special polymer coating, which helps minimize galvanic corrosion between stainless steel and aluminium while increasing resistance to moisture, salts, and other harsh outdoor conditions.

Color-Matched Heads

The countersunk heads are precision coated in Brown, Grey, and Beige, allowing a perfect match with the most popular composite decking colours and providing a clean, elegant finished appearance.

Key Features

SUS410 (AISI 410) Martensitic Stainless Steel
Manufactured from high-strength martensitic stainless steel, specifically selected for self-drilling screws used in aluminium profiles.

Benefits:

High hardness
Excellent mechanical strength
Ideal for self-drilling applications
Suitable for aluminium substructures

Additional Protective Polymer Coating

A specially formulated heat-cured polymer coating provides enhanced protection when used with aluminium profiles.

Advantages:

Reduces the risk of galvanic corrosion between stainless steel and aluminium
Improves moisture resistance
Increases resistance to salts and outdoor contaminants
Extends the service life of the fastener
Provides long-term protection in demanding outdoor environments

Self-Drilling Point

The specially designed drill point enables direct installation into aluminium profiles with wall thicknesses of up to 3 mm, eliminating the need for pre-drilling.

Benefits:

Faster installation
Cleaner drilling
Reduced installation time

Optimized Thread Design

The thread geometry is specifically engineered for aluminium, creating a secure and reliable connection.

Benefits:

Fast and smooth installation
High pull-out strength

Color-Coated Countersunk Heads

Precisely coated heads in Brown, Grey, and Beige blend seamlessly with composite decking boards. Once installed, the screw heads remain discreet and preserve the deck's clean appearance.

Torx Drive

The Torx T20 drive provides excellent torque transfer while minimizing bit slip, ensuring fast, accurate, and secure installation.

Applications

Suitable for:

Starter installation of solid composite decking boards
Composite decking on aluminium substructure profiles
Aluminium profiles with wall thicknesses up to 3 mm
Professional decking systems
New deck installations and renovation projects
Outdoor structures exposed to moisture and normal salt environments

Installation Recommendations

For the highest quality connection and the best visual finish, we recommend pre-drilling the composite decking boards and countersinking the screw head before installation.

The self-drilling point is specifically designed to drill directly into aluminium profiles up to 3 mm thick, eliminating the need to pre-drill the aluminium substructure.
