Description
A.O. Smith / Century Motor Thru Bolts – 10/32 x 9" Long with 3" Threaded End (16285658)
Note: This item is obsolete – no direct replacement available. Designed for legacy A.O. Smith Electric Motors and Century Electric Motors, these thru bolts are the precise mounting hardware you need to service older equipment that still operates in HVAC, pool, spa, and industrial applications. If your motor installation or repair calls for reliable through-bolt fasteners with an extended threaded section, this part is built to match the original specifications and fitment you’ve relied on for years.
Why these thru bolts matter for your legacy motor installations
Through bolts are essential for securing motors to form factors where the threaded end engages internal components or mounting plates. The 10/32 thread size is a common standard for older A.O. Smith/Century motors, and the 9" overall length ensures adequate engagement without compromising alignment. The 3" threaded end provides ample thread length for solid, vibration-resistant fastening in environments where motors face thermal cycling and operational stress.
Key features and benefits
- Exact fit for A.O. Smith / Century motors: Specifically designed to align with the mounting patterns of classic Century/A.O. Smith motor assemblies.
- Through-bolt design with extended thread: 10/32 thread size paired with a 3" threaded end enables secure, adjustable mounting across a range of motor frame configurations.
- Sourcing for legacy equipment: Ideal for technicians maintaining or restoring older HVAC, pool/pump, or machine setups that rely on original hardware specifications.
- Authentic lineage: Part of the long-standing A.O. Smith/Century product family, backed by decades of OEM alignment and field usage in residential, commercial, and industrial settings.
Use cases and who benefits
– Technicians performing maintenance on older pool and spa pumps, heaters, or cooling systems that originally used Century/A.O. Smith components.
– OEMs or repair shops servicing legacy HVAC equipment that requires authentic mounting hardware to preserve installation integrity.
– Facility managers overseeing inventories of replacement parts for aging motor fleets where authenticity and compatibility matter more than novelty.
Practical considerations
- Confirm compatibility with your motor’s mounting holes and frame before installation to ensure proper fitment and torque characteristics.
- Use with appropriate hardware and hardware-reinforced mounting surfaces to maintain vibration resilience and long-term reliability.
- Given the obsolescence status, plan for stock planning and compatible substitutions if you’re maintaining a large fleet of legacy motors.
For decades, A.O. Smith and Century motors have been trusted partners in motor technology across residential, commercial, and industrial sectors. While this specific thru bolt is part of a discontinued lineup, it remains a vital piece for authentic restoration and repair of classic equipment. If you’re rebuilding or maintaining legacy systems, these bolts help you preserve original performance and alignment, keeping your equipment operating with the familiarity and compatibility that technicians count on.
