Benefits #
Inch-series stainless steel countersunk machine screws at 1/2-inch provide flush fastening in US-specification equipment requiring corrosion resistance. The 82° conical head seats flush in standard inch countersinks. A2 (304) stainless steel eliminates coating degradation in humid and atmospheric environments. Cross-recessed drive allows controlled torque application. This diameter serves legacy US-specification machinery, marine hardware, and aerospace interior panels.
Common Applications #
Common applications for 1/2" inch-series SS countersunk machine screws include:
- Small US-spec instrument panels
- Legacy equipment flush covers
- Marine interior fittings (inch)
- Aerospace interior panels (inch)
- Small electrical enclosure covers
