Using the authentic Graco 126108 Shoulder Screw guarantees correct tolerances and structural integrity. Aftermarket substitutes often lack the proper shoulder length or thread strength, increasing the risk of component failure, vibration problems, or alignment issues during operation. OEM parts preserve equipment lifespan and maintain manufacturer-approved safety standards.
For best results, tighten the shoulder screw according to the torque values provided in your Graco equipment manual. Proper torque prevents loosening and ensures optimal load distribution across the connected components.
