6-32 x 1 3/4 316 Stainless Steel Button Head Socket Cap Screw is used when the fastener head remains visible and the surrounding equipment benefits from 316 stainless steel construction. The button-head design gives engineers a compact rounded profile, a broad bearing surface, and internal hex drive access, while the 316 stainless steel material is selected where additional corrosion resistance is needed compared with general-purpose stainless grades.

Typical applications include marine equipment and dock hardware, where the rounded head helps reduce snag points while 316 stainless steel supports saltwater and coastal exposure. It can also serve instrumentation and control equipment, where the button head provides a finished appearance on visible panels and enclosure hardware. The button-head geometry is different from a standard socket head cap screw: it keeps a lower, rounded profile while still providing socket engagement.

For the 6-32 thread and 1 3/4 in. length, the reference head diameter is 0.250-0.262 in. and the head height is 0.063-0.073 in. Use the verified head dimensions below when checking surface projection, socket access, and replacement fit.
