Screw, Machine, Hex Head, Cruciform Recess (10-32 x 1") NAS1801-3-16

Technical Description

Precision aerospace-grade, high-strength machine screw (PN: NAS1801-3-16) manufactured from premium 8740 hardened alloy steel. Features a fine 10-32 UNF-3A right-hand thread profile configuration with a nominal fastener length of 1.000 inch (1") and a full-thread shank structure running up to the head bearing surface. Engineered with a specialized dual-drive external hexagon head combined with a type 1 cruciform (Phillips) cross-recess drive, allowing high-torque tightening using standard hex sockets or cross-head tools while preventing driver slippage. Finished with a protective yellow cadmium/chromate plating providing exceptional resistance against outdoor environmental corrosion, hydrogen embrittlement, and surface galling in structural aircraft assemblies.
