Frequently Asked Questions
The 124886 dog-point set screw is used in several Graco electric and cordless sprayer models, including the 390 PC series, UltraMax II handhelds, and FinishPro II 395 PC. However, always cross-check with your specific model’s parts breakdown, because part usage can vary by serial number and production year.
While a generic 1/4-20 × 0.25-inch screw might seem to match, it's recommended to use the OEM 124886. The dog-point tip is specifically designed for proper seating in Graco assemblies, and substitutes may not provide the same durability or may damage mating components over time.
Inspect the screw during regular maintenance — signs that replacement is needed include: rounding or stripping of the head, damaged threads, or a worn dog-point tip. If the screw loosens frequently or fails to hold securely, it’s best to replace it with the genuine 124886 to maintain safe operation.
Graco does not always publish a specific torque for this small set screw. As a general rule, tighten evenly until the dog-point seats firmly, but avoid over-torquing. If your service manual provides a torque spec, follow that. Otherwise, hand-tighten with an Allen wrench and check for security during follow-up inspections.
