Fitment Guidance
- Verify the exploded diagram reference and quantity for your exact model revision (Series A/B/C, etc.).
- Do not substitute look-alike #8-32 × 3/8" screws with different head styles (e.g., pan, oval) unless the parts manual permits it.
- Replace in sets where the assembly requires multiple identical fasteners to maintain clamp load and alignment.
Installer Notes
- Start fasteners by hand to avoid cross-threading into cast or aluminum components.
- If specified by the manual, apply appropriate thread sealant or threadlocker only where called out.
- Tighten evenly in a criss-cross pattern when securing covers/plates for proper seating.
Frequently Asked Questions
Not necessarily. 100258 specifies a fillister-head machine screw for a particular position in Graco assemblies. Other Graco part numbers may share the size but use different head styles or coatings. Always match the exact part number in your manual.
Quantity depends on the model and sub-assembly. For example, the 5 Gallon Duo Paint Sprayer pump assembly calls for around 6 pcs, while the LINE LAZER LD sub-assembly lists 4 pcs. Check your machine’s current parts list for the precise count.
Only if the Graco manual allows it. Changing material or finish can alter torque-tension characteristics and corrosion behavior. Use OEM 100258 to ensure fit and torque values match Graco specifications.
No. Washers and related hardware are listed separately in Graco parts lists. If your diagram shows lockwashers or tabs at the same location, order those by their own part numbers.
Graco torque values are assembly-specific. If a torque is called out in your manual for the fastener location, follow it. Otherwise, tighten to a typical #8-32 machine screw value appropriate to the base material, avoiding over-torque on aluminum or plastic parts.
