What It Does

Secures critical components to prevent unwanted movement or misalignment during operation.
Maintains assembly integrity in high-duty sprayer systems.
Correct 1/4"-20 × .25 sizing ensures proper thread engagement and fit on compatible units.

Fitment & Replacement Tips

Confirm by checking your model’s parts manual and locating item 100002 in the relevant assembly diagram.
Do not substitute different thread sizes or lengths; incorrect hardware can damage mating parts.
If a threadlocker is specified in the manual, apply the correct grade during installation.
Tighten to the guideline in your service manual (if provided) to avoid over- or under-torque.

Frequently Asked Questions

Functionally the size matches, but OEM fasteners align with Graco’s engineering specs and materials. For critical assemblies, use the genuine part unless your manual allows an equivalent.

Check your unit’s parts manual using the model and serial range. Locate the assembly diagram (e.g., hydraulic pump/reservoir) and verify the listing for 100002.

Availability can vary by model and region. If listed as NLA (no longer available) for your machine, your manual or a Graco dealer may provide an updated replacement or kit solution.

Use only if specified by the service manual for your assembly. When specified, apply the recommended grade and allow proper cure time before operation.

Torque is assembly-specific and not always published for small hardware. Refer to your model’s service documentation; if absent, follow best practices and avoid over-tightening.
