The GRACO 867300 is an internal tooth lock washer designed to secure fasteners in GRACO equipment. Its material is typically steel, and it is used to prevent loosening of bolts and nuts in high-vibration environments.

Key Features:

• Internal Tooth Lock Washer
• Steel (assumed, as this is standard for lock washers in industrial applications)
• Designed for use with GRACO equipment requiring secure fastening; compatible with standard bolt and nut sizes matching the washer's inner diameter
• Internal tooth design for superior grip and vibration resistance
• Prevents loosening of fasteners in high-vibration environments
• Durable steel construction for long service life

Applications:
Used in GRACO equipment assemblies where secure fastening is critical, such as pumps, sprayers, and other industrial machinery exposed to vibration and dynamic loads.

Installation Notes:

• Using genuine GRACO lock washers ensures proper fit, performance, and reliability in equipment assemblies.
• Place the internal tooth lock washer between the bolt head/nut and the surface to be fastened
• Ensure the teeth face the surface for optimal grip
• Tighten the fastener to the recommended torque for the application
• Inspect for wear or deformation during routine maintenance
