Why Use the OEM 113471 Screw?
Using the correct Graco part like the 113471 ensures you maintain the intended clamping load, torque spec, and mechanical integrity of your equipment. Generic bolts may differ in grade, thread tolerance, or finish, which could compromise performance or safety.
Installation Tips
- Always refer to your machine’s service manual for the correct torque value when installing.
- Inspect the screw periodically for wear, corrosion, or thread damage.
- If replacing, make sure to match the original specifications – do not substitute with a lower grade.
Frequently Asked Questions
The Graco manuals list this as a Cap Screw, Hex HD, Grade 5. In the 308611 parts list, it’s specified as 3/4-16 UNC × 5.5 in. :contentReference[oaicite:6]{index=6}
While a generic bolt of similar dimensions might physically fit, it's not recommended. The OEM 113471 is rated for the specific torque and load required by Graco machines. Using a non-OEM part may compromise clamp force, lead to loosening, or cause damage.
It’s good practice to inspect this screw during regular maintenance — especially after heavy use or vibration exposure. Look for thread wear, deformation, or corrosion. Replace if any signs of compromise are detected to maintain safety and reliability.
