Product Description
The F-440-1 is a hexagonal fastener designed specifically for applications where protrusions are not permitted on either side of the mounting surface. This "dual-flush" capability is essential for high-density electronic enclosures, slide-out components, or any assembly where clearance is restricted and a smooth finish is required.
Flush Installation: Eliminates protrusions on both sides of the sheet for a clean, unobstructed surface and improved aesthetics.
Corrosion Resistance: The 300 series stainless steel material offers excellent durability and resistance to oxidation.
High Torque Resistance: The hexagonal head provides a strong mechanical lock to prevent rotation during high-torque screw installation.
Manufacturing Efficiency: Removes the need for secondary processes like deburring, tapping, or welding, reducing overall production costs.
