Hex Jam Nut for Titan HVLP AirSpray Equipment

The Titan 770-181 Hex Jam Nut is a genuine OEM replacement fastener used on HVLP AirSpray Quart Cups and ProFinish TS40/TS50 sprayers. Jam nuts are thinner than standard nuts and are typically used to lock another nut in place or to secure components in tight spaces.

A missing, stripped, or corroded jam nut can cause loosening of critical assemblies, leading to air leaks, fluid leaks, or misalignment of spray head components. Replacing with the correct specification nut restores secure fastening and reliable equipment operation.

Service Guidance: When replacing a jam nut, inspect the mating threads on the bolt or stud for damage. Use a wrench to tighten to the recommended torque; do not overtighten, as jam nuts are thinner and can strip more easily.

What the hex jam nut does

Secures components	Locks assemblies in place against vibration
Locking function	Often used as a secondary nut to prevent loosening of a primary nut
Space‑saving design	Thinner profile allows use in confined areas

When replacement is recommended

Stripped threads	Nut spins freely or will not achieve proper torque
Corrosion / rust	Heavy rust weakens the nut and damages threads

Frequently Asked Questions

It is a hex jam nut used on Titan HVLP AirSpray Quart Cups and ProFinish TS40/TS50 sprayers. It is a thin nut typically used for locking or in confined spaces.

A jam nut is approximately half the thickness of a standard hex nut. It is often used as a lock nut – tightened against a primary nut to prevent loosening – or where space is limited.

Signs include visible rust or corrosion, stripped threads (nut spins without tightening), a missing nut, or the assembly becoming loose during operation.

While a nut of the same size and thread pitch may physically fit, Titan recommends using genuine OEM 770-181 to ensure correct hardness, finish, and corrosion resistance for the spray equipment environment.
