Graco 100902 Screw Mach Pnh

Graco 100902 – Screw, Mach PNH (¼-20 x 1½")

OEM replacement round-head machine screw used where specified in Graco assemblies. Ideal when your parts manual calls out 100902.

Compatible Machines

This is a generic hardware fastener. Graco lists it by part number in the specific assembly or accessory bill of materials. Because of that, compatibility is model-specific to the assembly that uses it.

• Used wherever the parts list explicitly calls out 100902 (Screw, Mach PNH ¼-20 x 1½").
• Commonly appears with surge tank / fluid filter clamp and similar mounting hardware (verify in your manual).
• For a precise fit, match your sprayer’s parts list or assembly diagram to 100902.

Specifications

How to Confirm Compatibility

1. Open your sprayer’s parts manual or assembly diagram.
2. Locate the relevant assembly (e.g., surge tank, filter clamp, bracket).
3. If the bill of materials lists 100902, this screw is correct for your unit.
4. If a kit is listed (with screw, nut, washer), order the kit instead of individual pieces.

Buying Tips

• Match thread (¼-20) and length (1½") exactly to your manual.
• If your manual calls for a nut (e.g., 100015) and lock washer (e.g., 100016), add them to cart together.
• Keep a few spares—fasteners are small but critical for uptime.
