Frequently Asked Questions

Dimensionally it matches a 3/8-16 UNC-2A × 1 hex-head cap Screw. However, Graco specifies materials and finishes based on application. For safety and warranty, use genuine Graco parts or an exact-spec equivalent verified against your manual.

Torque is assembly-specific. Refer to your machine’s service manual for the correct torque value for locations using the 3/8-16 fastener. Over- or under-torque can damage components or lead to loosening.

Quantity varies by assembly (e.g., drum covers may specify multiple pieces). Check the exploded diagram and parts list for your exact model to confirm counts and positions.

If a screw is damaged or corroded, replace it. In critical joints, replacing as a set can help maintain uniform clamp load. Follow any Graco guidance provided for your assembly.

Consult the latest Graco service manual for your unit. Look for bill-of-materials lines calling out “Screw, cap, hex head, 3/8-16 × 1, sst (102471).”
