This washer features a 5/8" inner diameter, 1-1/2" outer diameter, and 0.078" thickness, providing excellent load distribution and surface protection.

Key Features:

• 316 stainless steel construction for maximum corrosion resistance in saltwater applications
• 5/8" inside diameter fits standard 5/8" bolts and fasteners
• 1-1/2" outside diameter provides wide bearing surface

These flat washers are essential hardware for distributing fastener loads across a wider area, preventing damage to softer materials and reducing the risk of fastener pull-through. The 316 stainless steel grade offers superior pitting and crevice corrosion resistance compared to 304 stainless, making it the preferred choice for below-waterline marine applications, saltwater exposure, and harsh chemical environments.
