S-93550A125 2.125" ID x 3.75" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion protection with black-oxide steel finish for extended service life in harsh industrial environments
• Precise dimensional fit with 2.125" ID and 3.75" OD ensures perfect alignment and load distribution for 2" screw applications
• Heavy-duty construction with 0.235-0.265" thickness provides reliable bearing surface and prevents fastener embedment
• Industry compliance assurance with RoHS 3 and REACH regulations for safe, environmentally responsible manufacturing
• Optimal material strength from steel construction delivers consistent performance under mechanical stress
• Standard inch sizing ensures compatibility with existing industrial equipment and replacement part inventories

Professional Applications & Engineering Value

These black-oxide steel flat washers deliver critical engineering value in demanding applications where corrosion resistance and dimensional precision are paramount. The black-oxide surface treatment creates a protective barrier against moisture and chemical exposure, significantly extending component life in outdoor, marine, and industrial environments. Engineered specifically for 2" screw applications, the precise inner diameter (2.125") and outer diameter (3.75") ensure optimal load distribution across fastened joints, preventing surface damage and maintaining structural integrity. The substantial thickness range (0.235-0.265") provides excellent bearing surface for heavy-duty washers used in construction equipment, machinery assembly, and structural steel connections where vibration resistance and long-term reliability are essential.
