Frequently Asked Questions

Yes—Graco 115478 is a genuine OEM machine screw designed to meet factory specifications for Graco sprayers.

Confirmed usage appears in ProX 17/19/21, TexSpray Mark V, and Ultra Max II 1095/1595 parts lists. Always verify with your specific parts manual.

It accepts a Torx driver for best engagement, and also a flat slotted screwdriver in tight spots (dual-drive pan head).

Quantity varies by model and revision. For example, some ProX series use multiple 115478 screws on control-cover assemblies.

Disconnect power, support the cover or bracket being removed, and start by hand to avoid cross-threading. Use a Torx driver to torque evenly and prevent cam-out.
