Sealand Hex Shoulder Bolt – 600347785
If you're rebuilding or servicing a Sealand toilet pump assembly, a small overlooked part like a shoulder bolt can be the difference between a smooth repair and a leaky, wobbly result. The Sealand 600347785 hex shoulder bolt is the exact fastener designed to hold pump and motor components in precise alignment, giving the moving parts inside your marine sanitation system a stable pivot point that resists loosening from constant vibration and moisture exposure.
What makes a shoulder bolt different from a standard bolt is that smooth, unthreaded section between the head and the threads. That shoulder acts almost like a built-in bushing, letting a bracket, lever, or pump component rotate or slide freely around it without the threads ever coming into contact with the moving part. In a marine environment, where saltwater, humidity, and constant motion put extra stress on hardware, having the correct OEM fastener matters more than it might seem. A generic substitute can wear unevenly or allow play in the assembly, leading to premature failure down the line.
Boat owners and RV techs who keep a Sealand or Dometic sanitation system running smoothly know that small parts like this one rarely get attention until they're missing or stripped. Ordering the correct part number ahead of time saves a trip mid-project and keeps the whole pump assembly working the way it was engineered to.

Frequently Asked Questions
Q: Is the Sealand 600347785 hex shoulder bolt compatible with older Sealand toilet models?
A: It is designed as an OEM replacement for Sealand and Dometic pump assemblies that originally used this part number, so checking your unit's parts diagram before ordering is recommended to confirm exact fit.
Q: Can this bolt be used outside of marine sanitation systems?
A: While it is built for Sealand pump assemblies, hex shoulder bolts of this type can also serve in other mechanical applications requiring a precise pivot or alignment point, not limited to marine use.
Q: Do I need any special tools to install this shoulder bolt?
A: A standard wrench or socket sized for the hex head is typically all that's needed, along with care to avoid over-tightening past the shoulder's design tolerance.
Q: How do I know if my current bolt needs replacing?
A: Signs include visible corrosion, stripped threads, looseness in the pump lever or bracket, or unusual play in the moving assembly during operation.
Q: Is this a single bolt or does it come as part of a kit?
A: This listing refers to the individual hex shoulder bolt; it can be ordered on its own or alongside other pump hardware depending on what your repair requires.
