• Exceptional durability provided by high-quality steel construction for long-lasting performance in demanding applications
• Consistent thickness control with 0.032" dimension and -0.002" to 0" tolerance for uniform pressure distribution
• Environmental compliance assurance meeting RoHS 3 and REACH standards for sustainable manufacturing
• Reduced maintenance requirements through precision engineering that minimizes wear and tear on connected components
• Versatile industrial compatibility designed specifically for inch-system applications requiring 2-1/2" shaft diameters

Professional Applications & Engineering Value

This precision steel flat washer delivers exceptional engineering value in industrial settings where dimensional accuracy is critical. The carefully controlled 2.502" inner diameter with minimal tolerance ensures perfect seating on 2-1/2" shafts, eliminating play and reducing vibration-induced failures. The steel construction provides superior strength for heavy-duty applications, while the precise 3.25" outer diameter maximizes bearing surface area to distribute loads effectively. This inch-system washer solves common assembly challenges by maintaining consistent thickness across the entire surface, preventing uneven pressure that can lead to component deformation. Ideal for machinery, automotive, and industrial equipment applications, this high-tolerance washer ensures long-term reliability in demanding environments where precision fit is non-negotiable.

Specification Summary & Compliance
