Benefits
#
Stainless steel countersunk socket screws at 12mm provide flush fastening in environments where corrosion resistance is required. The 90° conical head seats fully within a prepared countersink, creating a continuous flat surface. A2 (304) stainless steel eliminates coating degradation issues that affect plated carbon steel fasteners in humid or corrosive environments. The conical head self-centres in the countersunk hole, improving positional accuracy. Internal hex drive allows single-side installation in confined assemblies.
Common Applications
#
Common applications for M12 stainless steel countersunk socket screws include:
- Precision instrument mounting surfaces
- Small enclosure flush panels
- Medical equipment housings
- Laboratory equipment surfaces
- Food processing small equipment
