GRK Products

RSS™ Rugged Structural Screws
GRK's patented Rugged Structural Screws are a lag screw replacement made of specially hardened steel to provide high tensile, torque and shear strength. Sharp threads and points bite instantly into building materials (including hardwood) - reducing splitting. The RSS™ has a round head with a built-in shield (washer type head) and is available in a variety of sizes up to 16". RSS™ fasteners are available with (gold colored) Climatek™ coating and in PHEinox™ stainless steel. Discerning log home builders appreciate the quality, appearance, ease-of-use and technical merits of GRK Fasteners for their projects.

The RSS™ LTF Timber Frame Fastener produces extreme pressure, pulling the log down and eliminating the need to add a washer as required for common lag screws. No predilling is required. The head can be countersunk 1" - 3" without pre-drilling a countersink hole. The exclusive "CEE" thread slightly enlarges the hole for the new screw shank, and allows the log to settle without restriction.

The RSS™ LPS Panel Fastener has an extremely strong, low profile washer-type head that provides superior hold down pressure to the panel without damaging softer materials.

Trim™ Head Screws
GRK's patented Trim™ Head Screws are an excellent choice for decks, most fine carpentry applications, as well as window extension jambs and more. GRK's Trim™ Head screws feature the smallest screw head in the industry - and are available in sizes from 1 1/4" (30 mm) to 5" (125 mm). The Trim Screws' exceptionally small head, along with the thread design, prevent most material splitting. In composite deck construction (and with tropical hardwoods), the trim head is designed to disappear beneath the surface of the deck, resulting in a more attractive appearance. Many sizes are also available in PHEinox™ stainless steel.

In the patented RT Composite™ Trim™ Head Screw, GRK has modified its innovative FIN/trim™ Head Screw to include reverse threading under the head of the fastener . Based on extensive tests, GRK has found that the reverse thread helps the screw head disappear beneath the surface of the wood composite material reducing or eliminating the dimple that sometimes appears when using the FIN/Trim™ screw.

The Top Star™ makes it easy to adjust door and window frames at any time (e.g., to compensate for log settlement). The TopStar™ is available in a variety of sizes from 2 1/2" up to 16".

R4™ Multi-Purpose Screws
GRK's patented R4™ self-countersinking screw has cutting pockets under the head which act like a drill point to countersink the head of the screw. This guarantees the most accurate countersink hole possible. The R4™ eliminates pre-drilling and stripped heads, and is available in over 60 sizes - with either Climatek™ coating or PHEinox™ stainless steel. The R4™ is recommended for use in: wood, particle board, sheet metal, cement fibre board, composite decking and wood decking.

MSS™ Metal Siding Screws
The patented MSS™ was developed to meet the industry's need for a more sophisticated fastener for metal roofs and siding. The MSS™ screw has an integrated self-sealing washer head. The MSS™ is available with a Zip Tip (for metal to wood) or a Drill-tip (for metal to metal). No pre-drilling is required. The MSS™ is available in different colors to match siding appearance and is powder coated for exceptionally high corrosion resistance.
