If you have trouble putting in screws with a drill, the GRK's are for you. These screws reduce friction because they have "W" cuts within the first few threads. These small blades actually cut the wood fibers like a saw blade instead of pushing them aside. The GRK's are also much stronger than decking screws that you will find in a home improvement store. The 2" sheeting screw has a shear test of 687 lbs! The star head is also very deep to virtually eliminate stripping. GRK screws are more expensive than the cheap ones that break or strip during installation and then snap after a winter/spring season - but they are well worth it.

The GRK's are shipped to you via USPS Flat Rate Priority Mail. The box is heavy but well protected with interior boxes that act as cells to hold everything in tight. How many screws will you need for your project? Are you building the ramp from scratch or are you just re-sheeting an existing ramp with a high quality ramp surface such as Skatelite Pro or Ramp Armor Deluxe. A 4x8 sheet of ramp surfacing typically takes 70 screws to really screw it down with a tight grid pattern. So, if you purchased 16- 4x8 sheets of ramp surfacing you would need 1120 2" sheeting screws.

Depending on the ramp, there is also the plywood layer or layers underneath the ramp surfacing. These sheets do not need 70 screws but probably 40 will do per sheet layer. The price for these screws is listed at the bottom of this page and is for a 200 count of screws. If you want to purchase 1200 screws, simply hit "Buy Now" and choose 6 for the "Quantity" and hit "Update Totals" to order the correct amount. A small USPS Flat Rate Priority Mail shipping charge will also be added to the total just before shipping. Star Bits will be included in your order free of charge.



GRK’s R4™ screw has a new under head with saw-blade like cutting teeth and six self-contained cutting pockets. Together these features act like a circular saw blade, transporting the "drill dust" away from the edge of the screw hole while cutting a perfectly clean hole into even the most brittle materials without cracking any surface treatment. The screw head closes the hole off with precision, leaving no damaged fibers around the head. R4™ screws which are 2" and longer have a four threaded CEE thread that enlarges the screw hole for the non-threaded portion of the fastener. This technological advancement allows the wood to settle easily and increases the screw’s drawing strength, reducing the friction on the screw shank and lowering the driving torque. The R4™ is a multi-purpose screw that can be used in all woodworking and plastic applications.


The W-Cut™ is a patented thread design which acts like a saw blade cutting through any fibrous materials with ease. This unique design reduces the amount of torque required to install the screw, and maintains a high pull out strength. By cutting through, rather than pressing fibers aside, the W-Cut™ also reduces material splitting.

Climatek™ – GRK Fasteners All Weather Coating
GRK’s Climatek™ coating consists of a total of six layers of various materials, including three layers of zinc-polymer.
Climatek™ has been tested for salt spray resistance, and more importantly, for Kesternich durability.

Kesternich cycles are a more advanced way of testing a coated material. Each Kesternich cycle simulates heat, cold, wind, water, salt as well as a variety of other elements, whereas salt spray merely uses salt water for its tests.

Climatek™ passed 29 Kesternich cycles, making it the most advanced coating of its kind.

The GRK screws and countersinks worked perfectly. Zero screws broke, zero wood split and a nice tight bite throughout.

First, I wanted to let you know that it has been a real pleasure dealing with your company. Communication has been great and the assistance with tracking our shipments has been wonderful. Second, the countersinks you sent us are worth their weight in gold! The hardware, screws, countersinks etc. were great. We were able to obtain a much closer fit from our panels to our ramps than with the traditional screws. These countersinks have cut our labor down dramatically and we experienced no chipping while drilling. The accuracy we experienced was phenomenal. Thank you again and I look forward to doing business again in the future. Jose Pineiro - Assistant Superintendent of Parks & Facilities - Round Lake Area Park District

Those GRK screws are top notch! My brother who is a fabricator of all sorts of projects was so impressed with the screws he plans on using them in his next project. Thanks again for all your help, the ramp is REALLY COOL!"
