The Kreg SML-F125-5000 Zinc Pocket Screws are ideal for pocket-hole joinery projects with hard dense materials like cherry maple and oak. These screws have a 1 1/4-inch fine thread Maxi-Loc square drive heads and a self-tapping tip that eliminates the need for pilot holes. The flat bottom head fits tightly against pocket holes for secure pocket-hole joints. Zinc finish and dry-lubricant coating resist rust and make drilling easier. The smooth case-hardened steel shank turns freely for a tighter fit while the soft core prevents the screws from breaking snapping or bending while you drill. At Kreg woodworking is our passion.
