Benefits
#
The 3/16-inch stainless steel round head machine screw addresses fastening in imperial-dimensioned crowded panels. A2-70 grade provides 700 MPa tensile strength with inherent corrosion protection. The slotted drive eliminates the need for specialized driver bits. Simple head geometry keeps costs lower than cross-recessed alternatives for high-volume inch-specification assemblies.
Common Applications
#
3/16" SS round head machine screws (inch) are specified for US-spec space-constrained fastening:
- US-spec electrical panels
- Legacy machinery wiring
- Marine instrumentation (inch)
- Industrial control panels (inch)
- Lighting fixtures (inch spec)
