Metric Size A4 (316) Stainless Steel Button Head Socket Head Cap Screws
Metric Size A4 (316) Stainless Steel Button Head Socket Head Cap Screws
Metric Size A4 (316) Stainless Steel Button Head Socket Head Cap Screws are premium corrosion-resistant metric fasteners designed for demanding applications where durability, low-profile installation, and resistance to harsh environments are essential. Manufactured from A4 stainless steel, commonly associated with 316 stainless steel, these button head socket screws provide enhanced corrosion resistance compared with A2 (18-8) stainless steel, particularly in environments involving chlorides, saltwater, chemicals, and moisture.
The smooth, rounded button head design provides a lower-profile appearance than conventional socket head cap screws while offering a broad bearing surface. These characteristics make A4 stainless button head screws an excellent choice for marine equipment, food processing machinery, chemical facilities, wastewater systems, outdoor equipment, industrial machinery, and OEM assemblies.
A4 316 Stainless Steel Corrosion Resistance
A4 316 stainless steel contains molybdenum, which improves resistance to pitting and crevice corrosion in many chloride-containing environments. This makes Metric A4 button head socket screws particularly valuable for coastal, marine, chemical-processing, and other corrosive applications.
Application-specific compatibility should always be verified when fasteners will be exposed to aggressive chemicals, elevated temperatures, or severe operating environments.
Low-Profile Button Head with Hex Socket Drive
The button head configuration combines a smooth, rounded profile with an internal hex socket drive for positive tool engagement. The low-profile head is ideal where space is limited or where a clean, finished appearance is preferred.
Premium Metric Stainless Steel Fasteners
Available in multiple metric diameters, thread pitches, and lengths, A4 stainless button head socket screws provide versatile fastening options for manufacturing, construction, fabrication, repair, and maintenance.
For applications requiring superior corrosion resistance, metric threading, compact head geometry, and dependable fastening performance, Metric Size A4 (316) Stainless Steel Button Head Socket Head Cap Screws provide an excellent solution for challenging industrial and environmental conditions.
