R4™ MULTI-PURPOSE FRAMING SCREWS Frame with Ease and Confidence

GRK’s R4™ self-countersinking screw has a patented underhead with saw-blade like cutting teeth and six self-contained cutting pockets. Together they act similar to 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.

This design enhances the R4™’s versatility by allowing the fastener to countersink into even the hardest woods. The head ofthe screw closes the hole off with precision, leaving no damaged fibers around the head.

R4™ screws 2” and longer have a four threaded CEE Thread. This enlarges the screw hole for the non-threaded portion of the fastener, allowing the wood to settle easily. It increases the screw’s drawing strength and reduces the friction on the screw shank that lowers the driving torque.

ESR-3201 Approved for structural application.

RSS™ RUGGED STRUCTURAL SCREWS Speedy Lag Bolt Alternative with Immense Drawing Power

GRK’s RSS™ screw is made of specially hardened steel to provide you with high tensile, torque and shear strength. The sharp threads and points bite instantly into the material (including hardwood), reducing the splitting effect due to smaller shanks.

RSS™ screws that are 3”1/8 and longer have CEE Threads which enlarge the screw hole for the non-threaded portion of the fastener, allowing the wood to settle easily and increases the screw’s drawing strength. The CEE Thread also reduces the friction on the screw shank which can result in lowering the driving torque and the likelihood of splitting the wood. This is why the RSS™ screw is an efficient lag screw alternative.

Our round head with built-in shield (washer type head) has no sharp edges like conventional lag screws. The added shoulder (nominal diameter) underneath the washer has the ability to center the RSS™ screw in pre-drilled hardware like hinges and connector plates.

KAMELEON™ COMPOSITE DECK SCREWS Heads Blend in with Decking. No Mushrooming Effect

GRK’s Kameleon™ screws are an excellent choice for composite and PVC decking applications. The underhead has saw-blade like cutting teeth that cut a perfectly clean hole into the decking.

The Kameleon™ also features five to seven rings that have three indented fiber traps on each ring designed to trap fibers and eliminate the mushroom effect.

The CEE Thread feature enlarges the screw hole allowing the composite decking to settle easily, increases the screw’s drawing strength, and reduces the friction on the screw shank, which can result in lowering the overall driving torque.

The Kameleon™ is also available in many different colors including: Grey, Sand, Tan, Brown, and Redwood. Plus, Trex Select® approved colors Pebble Grey, Saddle, Woodland Brown and Madeira.

FIN/TRIM™FINISHING TRIM HEAD SCREWS Smallest Head on the market for a Clean Finish

GRK’s Trim™ Head screws are an excellent choice for most fine carpentry applications, as well as window extension jambs and more. Our Trim™ Head screws have the smallest screw head available; with screw lengths from 1”1/4 (30 mm) to 5” (125 mm).

Most material splitting is prevented because of the Trim™ Head screw’s exceptionally small head and the W-Cut thread design.

Fin/Trim™screws are also available in white Climatek™coated finish to blend in with white wooden trim boards.

RT COMPOSITE™ EXTERIOR TRIM SCREWS Reverse Thread Design Prevents Mushrooming

GRK has modified its innovative FIN/Trim™ Head screw to include reverse threading un-der the head of the fastener. This technology makes the RT Composite™ Trim Screw ideal for use in composite and cellular PVC trim.

Based on extensive tests, GRK has found that the reverse thread helps the screw head disappear beneath the surface of the classic wood composite material, reducing or eliminating the dimple that sometimes appears when using the FIN/Trim™ screw.

The reverse thread feature is available in RT Composite™ screws from 2” to 3-1/8” in length in both regular Climatek™ coating and in white Climatek™ coated finish to blend in with popular white exterior compos-ite and cellular PVC trim.

IBC/IRCCOMPLIANT

For interior / exterior use in; exterior PVC trim (Azek, Kleer, Koma), no pre-drilling is necessary. Climatek™coated screws work well with CAMO system.

LOW PROFILE CABINET™ SCREWS Built-in Washer Head Presses Flush against any Material

GRK’s Cabinet™ screws are designed specifically for use in cabinet construction and installation. Cabinet™ screws are manufactured in a #8 gauge (4 mm) diameter for universal size convenience. These screws are thin enough to prevent most material splitting, while providing sufficient strength to guarantee a secure installation. The washer head design presses flush against any material surface.

Builders have discovered that short Cabinet™ screws can sometimes be used in vinyl siding installation, which makes this fastener idealfor both interior and exterior applications.

The Cabinet screw can also be used for light duty framing applications where a smaller diameter shank is necessary, yet a need exists for drawing power delivered by the washer head.

Caliburn™, Caliburn™ PH, Caliburn™ XL

Note:All values are based on close tolerance holes drilled a minimum of 1/4” deeper than embedment depth.

All listed values shown are average pull out and shear values for GRK's CALIBURN™, Caliburn™ PH and CALIBURN™ XL screws. Values will vary depending on a number of factors, including the quality of the concrete and size of the drill hole.

These figures are only offered as a guide. They are not guaranteed by GRK and not reduced by any safety factor.

For safety factor requirements in your area, contact your local building official, architect or engineer. Testing was performed according to ASTM standard E-488-96. The Caliburn™ XL has also an ICC Report ESR-3251. For most current information and technical specifications (shear & tension) visit our website: www.grkfasteners.com.

PAGE 36

LIABILITY AND WARRANTIESGRK Fasteners™ is a distributor of commercial grade fasteners. Conformance to “IFI” specifications is formally requested from our suppliers. The parts that we supply are quality inspected by independent labs.

We maintain lot traceability on all products listed in this catalog as long as they are in their original bulk boxes. Certifications are maintained on all fasteners.

Hydrogen Embrittlement: We require our platers and suppliers of plated fasteners to bake case hardened parts to “IFI” specifications. However, this process does not guarantee that hydrogen embrittlement will not still be present after baking or that it will not occur at a later date while in service. Specialized testing or a substitute part may be required, depending on the application.

Liability: Claims against GRK Fasteners™ shall be limited to a refund or credit for the price billed or paid for faulty or incorrect merchandise. Seller shall not be responsible for buyer's manufacturing costs, labor, alternate purchases, extra freight, replating, plating, lost profit, good will, recall costs, or other incidental or consequential damages.

Warranties: GRK Fasteners™ (“GRK”) warrants to the first retail purchaser that its Climatek™ coated and PHEINOX™ stainless steel screws will not rust under normal environmental conditions when used in accordance with the recommen-dations listed in GRK's Screw Selection Guide. This warranty is not transferable.

Refunds: In order to receive a refund, the customer must return to us at least 50 of the defective screws (including screw heads) for verification.

THERE ARE NO UNDERSTANDINGS, AGREEMENTS, REPRESENTATIONS OR ADDITIONAL WARRANTIES, EXPRESSED OR IMPLIED (INCLUDING ANY REGARDING WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE), NOT SPECIFIED HEREIN, RESPECTING ANY SALE OF PRODUCTS BY GRK FASTENERS™, (TO THE EXTENT PERMITTED BY LAW).

Drive with Speed, Quality and Confidence...

FASTER INSTALLATIONS: No pre-drilling and faster driving. Innovative, patented features like our Zip-Tip™ and W-Cut threads are specially designed to bite instantly and with less torque for effortless fastening. This allows for almost twice as many screws drive per battery life, especially with larger diameter screws. See for your self by visiting our web site for the RSS vs. Lag Screw challenge.

NO STRIPPING, NO SPLITTING, NO HEAD POPS: Quality products mean no wasted time on the job site. Labor savings turn into dollar savings, more so over the life of the project. Recessed star drive screws eliminate any stripping when used with GRK bits. Our CEE thread prevents splitting of wood for a quality installed look. Case hardened steel screws will not break and heads won’t pop during installation.

BUILDING CODE APPROVED: Confidence that our products will perform, even after the project is complete.
