A2 Stainless Steel Clamping Handle Screw (Long) are stocked to DIN 6336 / GN 313. The grade provides good general corrosion resistance and is largely non-magnetic; the practical service range is approx. -200 °C to +400 °C. Property data, grade comparison and the full size table follow.
Why Choose A2 Stainless Steel for Clamping Handle Screw (Long) — DIN 6336 / GN 313 (Series 044)
The most common stainless grade for indoor and general outdoor fasteners. For clamping handle screw (long) — din 6336 / gn 313 (series 044), this matters when good general corrosion resistance is the primary requirement.
Mechanical & Physical Properties
| Grade designation | A2-70 (304) |
|---|---|
| Magnetic response | Largely non-magnetic |
| Service temperature | approx. -200 °C to +400 °C |

Corrosion Behavior in Service
A2 (304) gives excellent atmospheric and most-water corrosion resistance and is the most common stainless for Clamping Handle Screw (Long) — DIN 6336 / GN 313 (Series 044) in indoor and general outdoor service. In chloride-bearing environments (marine air, road salt, swimming pools) consider stepping up to A4 (316).
Galvanic & Galling Considerations
Two important notes for stainless clamping handle screw (long) — din 6336 / gn 313 (series 044): (1) stainless can gall on stainless threads under load — use a thread lubricant or anti-galling compound, especially for M6 and below; (2) when joined to aluminum or galvanized steel, stainless can drive galvanic corrosion of the less-noble metal in wet service — isolate with a coating or sleeve where appropriate.
