Learn MoreGRK RSS Black Structural Screw is a structural fastener designed for ease of installation and the strongest of connections while providing a bold finish. With proprietary features like the Zip-Tip, and W-Cut thread, RSS fasteners drive into most woods without the need for pre-drilling.

Black coating matches decorative hardware for a cohesive looking deck build
Fast-biting Zip-Tip eliminates pre-drilling and provides a fast start making it easy to get the strongest of connections
Star drive recess has 6 points of contact, eliminating stripping
Unique thread design draws two substrates together while its washer head allows zero gap joints
Designed for outdoor and decking applications
W-Cut low torque, faster drive
Speedy lag bolt alternative with immense drawing power

What Customers Are Saying
The screws are praised for their exceptional quality, strength, and ease of use, being ideal for heavy-duty applications like repairing outdoor furniture, securing deck railings, and reinforcing joints. Customers highlight the self-tapping and self-drilling capabilities, large flange head, and Torx-style drive system as key features that prevent stripping and ensure a secure hold. While some find the screws more expensive, the consensus is that the superior performance and durability make them well worth the investment for critical structural projects.

The 5/16 X 3 1/8 were just what I needed for the .
They were just what I needed since they are slightly bigger than the ones I had. they fit much tighter than the ones that were in there. They worked really well.

Go to screws for window installs
The large washer head on these make installing windows a breeze. Beware the head does stick out a bit so account for that in your installs. Otherwise these are perfect.
