Application Guidelines

• Use a PZ2 (Star / Pozidriv) driver bit; Phillips or slotted bits will damage the head
• Drive at a true right angle to the surface; angled entry places unnecessary stress on the shank
• Fastening depth should reach approx. 60–70 % of screw length; excessive penetration may split the material
• Pre‑drilling is recommended in solid hardwood; reduces breakage risk
• Ease off torque as seating completes; stop once the head sits flush with the surface
• Select stainless steel screws for permanent exposure to rain, coastal air, or high humidity
• Store in dry, moisture‑free conditions; keep the box lid closed
