About the 1726641 Button Head Screw, M2x10 A4
Bossard article 1726641 is a hexagon socket button head cap screw in the ISO 7380-1 style, size M2 × 10 mm, in A4 stainless steel. Button head screws have a low-profile domed head with a hexagon socket drive and are used where a neat, low head height is preferred over a full cylindrical cap head. Bossard catalogue data for its ISO 7380-1 A4 range (the BN 8699 family) lists a minimum tensile strength of 600 N/mm² and a 0.2% proof stress of 450 N/mm² for the A4 material class, and notes that the M2 size is offered as a manufacturer extension below the smallest diameter covered by the ISO standard. A4 (316-type) stainless is chosen for enhanced corrosion resistance in marine and exposed environments.
