• Durable construction for repeated use

Applications:
Used to secure internal components in GRACO spray equipment and line stripers, ensuring proper alignment and function during operation.

Installation Notes:

• Using genuine GRACO set screws ensures proper fit, performance, and longevity of equipment, reducing the risk of component failure or misalignment.
• Ensure the equipment is powered off and depressurized before installation.
• Use the correct size wrench or driver to avoid stripping the screw head.
• Tighten the set screw to the manufacturer’s recommended torque to prevent over-tightening or under-tightening.
