The M2x5/BN855 is part of the BN855 series of Bossard fasteners, which is a line of stainless steel threaded rods and threaded studs used to join and secure components in a wide range of applications, from furniture to large-scale construction projects. The M2x5/BN855 is a metric, 8.8 grade, zinc-plated steel stud, measuring 2mm in diameter and 5mm in length. It has a fine thread, which is designed for maximum holding power and allows for a lower torque setting than its coarse thread counterparts. This fastener is commonly used to secure components that require reliable, permanent connections, especially in automotive and industrial settings.
