Frequently Asked Questions

It’s a socket-head cap screw (SCH). While hardware-store screws may match size, using the OEM Graco fastener ensures correct head profile and quality for the application listed in Graco manuals.

Check your sprayer’s exploded parts diagram for the exact part number 101888 and verify the required size 10-24 × 0.875. If it’s listed, this is the correct replacement.

Follow the Graco service manual for your model. If torque is specified, use a calibrated tool; otherwise, tighten to secure without stripping threads. Inspect threads and apply thread locker only if your manual calls for it.

Use the exact specification called out for your assembly. If your parts list shows a different screw, do not substitute; order the correct OEM part number for precise fit and safety.
