About the Bossard 1422111 Cap Screw M2.5
1422111 is the Bossard article number for a BN 610 hexagon socket head cap screw in the M2.5 x 8 mm size. BN 610 is Bossard’s designation for fully threaded hex socket head cap screws made to DIN 912 and ISO 4762 in A2 stainless steel; Bossard states the commercial A2 quality corresponds to property class 70, with a tensile strength of 700 N/mm². ISO 4762 fixes the geometry for the M2.5 size at a 4.50 mm maximum head diameter, a 2.50 mm maximum head height and a 2 mm hexagon socket, on an M2.5 x 0.45 coarse thread. Fully threaded means there is no plain shank: the thread runs the whole 8 mm to the head, which is what you want when the screw must engage a tapped hole through a thin clamped part.

Typical applications
M2.5 x 8 fully threaded is a small-electronics and precision-mechanics fixing: PCB and module mounting into standoffs, camera and lens brackets, connector and shield plates, and small covers on instrument housings. The full thread suits short-grip joints and blind tapped holes where a partially threaded screw would run its plain shank into the thread. The A2 grade keeps the fixing non-magnetic and corrosion resistant.
