Screw, Machine, 100° Flat Countersunk Head, Close Tolerance (10-32 x 1-1/32) NAS517-3-10

Technical Description

Precision aerospace-grade, high-strength close-tolerance machine shear screw (PN: NAS517-3-10) manufactured from premium 8630 or 8740 hardened alloy steel. Features a fine 10-32 UNJF-3A right-hand thread profile engineered with a highly controlled nominal shank diameter to optimize precision structural shear loading fits. Designed with a precise 0.625-inch (5/8") unthreaded grip length and a total nominal fastener length of 1.031 inches (1-1/32"). Configured with a 100-degree flat countersunk head incorporating a cruciform (Phillips) drive recess to deliver high-torque tightening and guarantee a perfectly smooth, flush surface finish. Treated with a yellow cadmium/chromate plating (per QQ-P-416, Type II, Class 2) providing superior resistance against wear, mechanical fatigue, and outdoor environmental corrosion in critical structural airframe skin panels.
