About the 1253743 Spring Washer M2.5 x 5.1, A4
Bossard article 1253743 is a split spring lock washer with flat ends from the Bossard BN 673 standard, sized for M2.5 fasteners. Per the distributor datasheet it has a 5.1 mm outside diameter and 0.6 mm section height, and is manufactured from A4 acid-resistant (marine-grade) stainless steel for use in corrosive environments. A split spring washer is a single-coil helical ring: when the joint is tightened the washer is compressed flat, and its spring action maintains tension in the bolted joint, resisting loosening under vibration. The flat-end split form is the classic spring lock washer geometry used under screw heads and nuts on small metric fasteners. As a catalogued Bossard standard part it is produced to consistent dimensional and material requirements, and BOLTON can quote it in workshop or production quantities with supporting documentation on request.
