NVS AISI 316 (A4-70) Stainless Steel Socket Head Cap Screw DIN 912
NVS AISI 316 (A4-70) stainless steel socket head cap screw: cylindrical head, hexagon socket drive, metric thread. Size range: M3–M20 · 10–150 mm (105 sizes). This screw has a cylindrical head with a hexagon socket and is tightened with an Allen (hex) key. Because the head can be sunk into a counterbored recess, it is used on machine joints with little space and where a neat look is wanted.
AISI 316 (1.4401) is a molybdenum-alloyed stainless steel. It resists chloride media, sea water and chemicals significantly better than grade 304 and is recommended for swimming pools, coastal sites, chemical plants and outdoor use.
Applications
- Boat, yacht and harbor hardware
- Water treatment plants and the chemical industry
- Machine joints in acidic or chlorinated environments
- Food and pharmaceutical production equipment

Selection and installation notes
- Stainless steel threads can gall (cold weld); lubricate the thread and tighten at low speed.
- A4 (316) is the right choice for sea water, chlorine and acidic environments; for fresh water and indoor use, A2 (304) is more economical.
- Contact with carbon steel or aluminum parts can cause galvanic corrosion; use an insulating washer if needed.
