Use the Kreg SML-F150-100 Zinc Pocket Screws with Kreg s pocket-hole jigs to create seamless durable joints. This 100 pack of screws works well with harder materials like cherry maple and oak. These screws have a zinc finish and a dry-lubricant coating for moderate rust protection and easier drilling. With a 1 1/2-inch fine thread these zinc screws with Maxi-Loc square drive heads are easy to drive into wood. The self-tapping tip eliminates the need for pilot holes even in the hardest materials. The smooth case-hardened steel shank turns freely for a tighter fit while the soft core prevents the screws from breaking or bending. The flat bottom head fits tightly against pocket holes.
