Frequently Asked Questions
It is used to secure pump components, frames, and structural parts within Graco spray equipment assemblies, ensuring stable mechanical connections during operation.
Grade 5 indicates medium carbon steel with heat treatment, providing higher tensile strength suitable for vibration-heavy industrial applications like spray equipment.
While commonly used in Graco equipment, it can also fit any compatible assembly requiring a 5/16-18 thread and 0.63-inch hex head cap screw of Grade 5 strength.
Replace it during maintenance if threads are stripped, corrosion is present, or if torque retention is compromised in pump or frame assemblies.
