NVS AISI 304 (A2-70) stainless steel button head socket cap screw: button (low dome) head, hexagon socket drive, metric thread. Size range: M3–M12 · 6–100 mm (90 sizes). This screw has a low, rounded (button) head with a hexagon socket. Its neat head does not protrude much from the surface, so it is preferred for exposed joints.
AISI 304 (1.4301) is a general-purpose chromium-nickel stainless steel. It is widely used in water, heating and cooling, compressed air, food processing and indoor and outdoor applications.
Applications
- Cover, panel and housing joints where the head stays visible
- Kitchen and food plant equipment
- Metal parts for decoration and furniture
- Surfaces where snagging must be avoided

Selection and installation notes
- Stainless steel threads can gall (cold weld); lubricate the thread and tighten at low speed.
- The head is low, so the socket depth is limited; for joints that need high tightening torque, a socket head cap screw (DIN 912) is more suitable.
- A2 (304) is suitable for fresh water, indoor and food environments; in sea water, chlorine and acidic environments, choose A4 (316).
- Direct contact between stainless steel and galvanized or carbon steel can cause galvanic corrosion; use insulation (washers, unions) between different metals.
