Rothoblaas KKT Color Screws, A4 Stainless Steel

Countersunk-head screws from Rothoblaas. KKT Color A4 screws by Rothoblaas represent a professional solution for outdoor timber structures where long service life and a clean aesthetic appearance are essential. The combination of A4 stainless steel and a color-coated countersunk head allows for nearly invisible joints with maximum resistance to weather conditions.

Key Features

Material: A4 stainless steel (AISI 316). Excellent corrosion resistance – suitable for exterior use, humid environments, pool areas, and locations with elevated salt exposure.

Colored countersunk head

The head finish allows matching with wood tones or façade cladding.

Once countersunk, the head is visually unobtrusive and does not disrupt the structure’s appearance.

Self-countersinking geometry

Milling ribs under the head ensure clean countersinking without wood splitting and without pre-drilling in softwoods.

Optimized thread

Fast and smooth driving
High joint strength
Reduced risk of material cracking

Torx drive

Ensures reliable torque transfer without slipping or damaging the screw head.

Applications

Wooden decking and substructures
Wooden façade cladding
Pergolas, fences, and garden structures
Shelters and timber buildings
Installation in exotic and hardwood species

Thanks to A4 stainless steel, they are also suitable for aggressive environments (pool chemicals, de-icing salts, coastal climates).

Technical Advantages

Long-term corrosion resistance
Aesthetically clean, nearly invisible joints
High mechanical strength
Professional solution for demanding exterior applications
