Benefits
#
Stainless steel pan head machine screws at 4mm provide corrosion-resistant metal-to-metal fastening with a wide bearing surface. The flat underside of the pan head distributes clamping force evenly, reducing localized stress on softer materials. A2 (304) stainless steel eliminates coating degradation in humid and atmospheric environments. Cross-recessed Phillips and Pozi drives reduce cam-out during powered installation. This diameter serves small electronics, instrument panels, and light machinery assembly.
Common Applications
#
Common applications for M4 stainless steel pan head machine screws include:
- Consumer electronics assembly
- Small instrument panel mounting
- Medical device housings
- Laboratory equipment frames
- Small electrical enclosure assembly
