GRK FIN/Trim Head Screws are an excellent choice for most fine carpentry applications. The FIN/Trim is also suitable for the installation of window extension jambs and molding. Special features include W-cut threads and Zip tips to help prevent wood splitting. The screws are Climatek coated for corrosion resistance.

• Designed for fine carpentry and installation of window extension jambs and moulding
• Use for composite decks and trim applications
• Climatek indoor/outdoor coating provides corrosion resistance (ICC-ES AC257 code approved for use in treated lumber)
• Small screw head with code approval for structural performance
• Zip-Tip provides a fast bite, eliminating pre-drilling for single step installation
• W-Cut threads allow for low torque and fast drive
• Trim head allows for a clean look
• Precision fit recessed star drive creates zero stripping with 6-points of contact

GRK RSS Rugged Structural Screw has a patented design and made of specially hardened steel to provide customers with high tensile, torque and shear strength. The sharp threads and points bite instantly into material, including hardwood, reducing the splitting effect due to smaller shanks. The GRK RSS series screws that are 3-1/8 in. and longer have 6 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.

• Easy to install lag alternative
• Ideal for carrying beam, playground equipment, ledger board, deck posts and stair rails
• Made of extremely high quality carbon steel that provides high tensile torque and shear strength
• Patented climatek coating for all weather corrosion protection
• W-cut provides low installation torque
• Self-tapping - no pre-drilling required
• 20% faster drive time
• Superior clamping force on the first drive
• Washer head for flush installation
• Recessed star drive allows for zero stripping with 6 points of contact
• Sharp zip-tip point bites instantly into material for ease of starting with minimal force and reduce splitting
• CEE thread design reduces friction and makes driving easier
• Ground contact lumber approved for worry free use in pressure treated lumber

GRK Fasteners Cabinet screws are designed specifically for use in cabinet construction and installation. Manufactured in a #8 (4 mm) Dia., these screws are thin enough to prevent most material from splitting while offering sufficient strength to provide strong and secure mounts. The washer head design presses flush against any material surface. The Zip-Tip eliminates the need to pre-drill.

• Use for cabinet construction and installation
• Flat low-profile washer head design for increased surface holding
• Zip-tip allows for no-pre-drilling and 1-step application
• W-cut low installation torque allows for fast driving and ease of install
• No pre-drilling required
• Climatek coating is AC257 code approved for use in treated lumber
• Star drive eliminates stripping for improved productivity
• Common project applications: remodeling, fencing, storage, cabinets, framing
• Washer style head seats flush and increases holding power for a secure installation
• Made of case hardened steel for high tensile, torque and shear strength
• Ground contact lumber approved for worry free use in pressure treated lumber
