GRK R4™ Multipurpose Screw

GRK’s R4™ screws have some of the most advanced technology around for faster screw driving with a whole lot less effort and no pilot holes required. Pilot holes are only needed if the building-material manufacturer requires it. Always check with the manufacturer’s literature for installation recommendations.

FEATURES

• Patented nib design under the head acts like a saw blade with six self-contained cutting pockets enabling countersinking in even exotic hardwoods.
• Extremely aggressive threads enable screws to penetrate fibrous material like OSB.
• Screws 2" and longer have a “CEE” four-threaded portion that enlarges the hole, reducing friction and increasing the “drawing strength”
• Screws can be used in all woods and plastic applications without shredding or cracking the surface.
• Screws can be used in all woods and plastic applications without shredding or cracking the surface. The 90º angle under the screw head fits perfectly into pre-countersunk holes for hardware brackets.
• Star Drive Recess

Stated lengths are “soft conversions” from metric lengths
