S-97093A128 10.2 mm ID x 18.1 mm OD DIN 128A Split Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance due to the curved split design, preventing fastener loosening in high-stress environments.
• Enhanced durability and corrosion protection from the zinc-plated steel construction, extending service life in industrial settings.
• Reliable, consistent performance ensured by the high Rockwell C44 hardness, maintaining washer shape and function under load.
• Guaranteed dimensional accuracy and interchangeability through compliance with the DIN 128A standard.
• Safe for use in regulated industries as it is RoHS 3 and REACH compliant, meeting strict environmental and safety directives.
• Easy identification and installation for M10 screw sizes with clearly defined 10.2mm ID and 18.1mm OD.
• Optimal spring action and tension from the specific 1.7mm thickness and 2.9mm overall height, providing a secure lock.

Professional Applications & Engineering Value

This M10 split lock washer is engineered to solve critical challenges in machinery, automotive, and structural assemblies where vibration and dynamic loads are prevalent. The curved split design and zinc-plated steel material work in tandem to create a powerful spring force that actively counters loosening, a common failure point in industrial equipment. Its Rockwell C44 hardness ensures the washer does not deform under high clamp loads, maintaining consistent locking pressure. By conforming to the DIN 128A specification, it guarantees precise dimensions for a perfect fit with M10 fasteners, streamlining assembly processes and reducing maintenance downtime. This makes it an indispensable component for engineers seeking reliable, long-term fastening solutions in demanding applications.
