Professional Applications & Engineering Value

Engineered for precision industrial applications, these metric steel washers solve critical assembly challenges where component alignment and surface protection are paramount. The 25.04mm ID with controlled tolerance ensures perfect fitment on standard 25mm shafts, eliminating play while the 42mm OD provides maximum load distribution to prevent surface damage and fastener embedding. Manufactured from high-grade steel, these flat washers maintain structural integrity under repeated stress cycles, making them ideal for heavy-duty machinery, automotive systems, and industrial equipment. The 3.0mm thickness delivers consistent spacing in bolted connections while resisting compression deformation, ensuring long-term reliability in high-vibration environments where maintenance downtime must be minimized.

Specification Summary & Compliance

This precision steel washer maintains exacting dimensional standards with ID tolerance (0mm to 0.21mm), OD tolerance (-0.57mm to -0.32mm), and thickness tolerance (-0.06mm to 0mm) for consistent performance. Manufactured to metric system specifications for 25mm shaft applications, the product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across international markets and regulated industries.
