About this DIN 7991 screw
This is a screw made to DIN 7991, in 304 Stainless Steel, at strength class A2-70, supplied plain, with an M2 thread and a 18 mm length. Every dimension is stated against the standard named above; where a tolerance class matters to your design, ask us and we will confirm it in writing before you order.
A screw threads directly into the parent material or into a nut, so the thread form, the point and the drive decide what it can be used for. Commonly used on machinery, tooling, appliances, electrical enclosures, furniture and automotive assemblies where the head has to sit low or be driven from one side only.
304 (EN 1.4301, A2) is the general-purpose austenitic stainless grade: good resistance to fresh water, food acids and atmospheric corrosion, non-magnetic in the annealed state. It is the default for indoor and general outdoor fastening where chlorides are low.
DIN 7991 is the same part as ISO ISO 10642, GB/T GB/T 70.3. Check the head geometry, the key size and the tolerances before substituting one for another — those do differ between systems.
