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.

How to Confirm Compatibility
- Open your sprayer’s parts manual or assembly diagram.
- Locate the relevant assembly (e.g., surge tank, filter clamp, bracket).
- If the bill of materials lists 100902, this screw is correct for your unit.
- 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.
Frequently Asked Questions
PNH denotes a pan/round head machine screw used in OEM assemblies where a low-profile rounded head is specified.
This listing is for the screw only. If your manual also lists a nut and lock washer, purchase those separately or order the specified kit.
Usage is assembly-specific. Any Graco model whose parts list explicitly calls out 100902 will use this screw. Check your manual’s bill of materials to confirm.
The material/finish is not specified here. Follow your manual’s notes; where material is critical (e.g., corrosive environments), the assembly documentation will specify the required grade/finish.
Do not substitute unless your parts manual allows it. Length, thread, and head style are selected to fit the specific bracket/clamp and maintain safety.
