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.

ULTIMATE LOAD VALUES Tensile and Shear

1 Overall length of fastener is measured from the underside of the head to bottom of the tip. See Figure 1.
2 Length of thread includes tip. See detailed illustration, Figure 1.
3 Minor thread, shank and outside thread diameters are shown in table without manufacturing tolerances.
4 Bending yield strength determined in accordance with ASTM D 1575 using the minor thread diameter.
