The AirSpray 770-573 Bolt is a genuine OEM fastener used in critical assemblies of the AirSpray HVLP ProFinish TS 40 and TS 50 spray guns. It is precision‑sized to ensure correct clamping force, alignment, and durability under normal operating conditions. Bolts in spray guns may be used to secure the air cap retaining ring, attach the fluid nozzle assembly, or fasten handle components.
Over time, bolts can become lost during maintenance, stripped from over‑tightening, or corroded due to exposure to moisture or cleaning solvents. A missing or damaged bolt can compromise the structural integrity of the gun, leading to misalignment, air leaks, fluid leaks, or inconsistent spray patterns. Replacing with the correct 770‑573 bolt ensures a proper fit and restores reliable operation.

When replacing a bolt, it is common to also inspect associated components that may have been affected by loose or damaged fasteners.
If the bolt secures the air cap ring, check the ring for damage and ensure the air cap seats correctly.
Loose fasteners can allow the fluid nozzle to shift; inspect for wear or misalignment.
Replace any gaskets or O‑rings that may have been damaged by loose or improperly torqued bolts.
