Product Summary
Largo Cross Recessed Countersunk Head Machine Screws are precision-manufactured according to DIN 965 y ISO 7046 standards, widely used in consumer electronics, household appliances, furniture
assembly, and precision instruments. Featuring a flat countersunk head with a Phillips (cross) drive, these Largo Cross Recessed Countersunk Head Machine Screws allow the fastener to sit flush with the
surface of the workpiece, providing a smooth, snag-free finish and high-speed installation compatibility.
-
✔ Flush Surface Integration: The 90-degree (Metric) or 82-degree (Imperial) head angle ensures the screw remains level with or below the surface for aesthetic and safety purposes.
-
✔ High-Efficiency Drive: The Phillips (Cross) recessed drive is designed for automated assembly lines, allowing for quick centering and reduced bit slippage.
-
✔ Precise Threading: Engineered with tight tolerances to ensure a perfect fit in pre-tapped holes or with matching nuts in metal-to-metal applications.

Installation & Usage Guidelines
-
Countersinking: Ensure the receiving hole is pre-drilled with the correct angle (90° for DIN/ISO) to the proper depth. If the hole is too shallow, the screw head will protrude.
-
Tool Matching: Always use the correct Phillips drive size (PH1, PH2, etc.). Using a tool that is too small or too large will "cam-out" and damage the screw head.
-
Tightening Torque: Do not over-torque when using stainless steel screws in stainless steel holes, as they are prone to thread galling. Use a moderate speed for installation.
-
Hole Alignment: Machine screws require a pre-tapped hole or a nut; ensure threads are aligned perfectly before driving to prevent cross-threading.

Q: Can I use DIN 965 screws in wood? A: No, these are Machine Screws designed for tapped holes in metal or for use with a nut. For wood, please see our Countersunk Wood Screws range.
Q: What is the difference between Phillips and Pozi drives? A: Phillips has a simple cross shape, while Pozi has extra tick marks for better grip. DIN 965 is typically Phillips, but Largo can manufacture Pozi versions upon request.
