RSS™ Technical Data

GRK Fasteners utilizes strict quality control procedures. Every batch of screws produced is independently random sampled and quality controlled to the highest standards.

Accreditations for independent test laboratories include:
ICC, CNLA, TÜV, Ü, ISO, DAR.

Installation procedure for Fasteners

Use appropriate driver bit.
No pre-drilling except where wood limitations require.
DO NOT use deck cleaners which contain bleach with coated metals.
Always consult wood supplier's / manufacturer's recommendations.
Metal to wood connections: avoid damage to the coating by pre-drilling the metal.
Cedar & Redwood: For best results use PHEinox Stainless Steel. If using coated fasteners, seal wood immediately with a quality sealer to lessen the likelihood of tanic acid stains.
