Benefits
#
Stainless steel countersunk machine screws at 4mm provide flush fastening in environments requiring corrosion resistance. The 90° conical head seats into a machined recess, creating a smooth surface that prevents snagging. A2 (304) stainless steel eliminates coating degradation issues in humid and atmospheric environments. Cross-recessed Phillips and Pozi drives provide better torque transfer than slotted alternatives. This diameter serves small enclosures, instrument panels, and electronic equipment covers.
