What It Is

This 2-pack set includes wheel bolts and matching lock nuts designed to secure lawn mower wheels to the axle. It replaces OEM part numbers 193406, 532193406, 137644, 532137644, 184219, 738-3056, 938-3056, and 73930600, and is intended for use on Craftsman, Cub Cadet, and Husqvarna riding mowers and zero-turn models.

Fitment & Compatibility

Before buying, confirm your mower uses a 5/16"-18 thread bolt (common for stamped steel axles). Measure the bolt shaft length—this set is typically for axles with a shoulder depth of about 1 inch. Check your existing bolt head shape: these are hex-head bolts, not flange or carriage bolts. Verify your mower model against the OEM numbers listed above. This set will not fit mowers with metric threads (e.g., 8mm or 10mm) or those requiring a different bolt length. If your axle uses a cotter pin or E-clip retention, this bolt-and-nut style won’t work.

Key Things to Know

• Quality: Zinc-plated steel resists rust, but lock nuts can lose grip after repeated removal—consider replacing the whole set if reusing old bolts.
• Installation: Easy—hand-tighten until snug, then torque to 10-15 ft-lbs. Over-tightening can strip the axle threads or deform the wheel hub.
• Common Gotcha: The lock nut is a nylon-insert type; if the nut spins freely onto the bolt by hand, the insert is worn and won’t lock properly. Replace immediately.
• Pack Size: Only 2 bolts and 2 nuts—enough for one mower axle (two wheels). For a 4-wheel mower, you need two packs.

Should You Buy It

If you own a Craftsman, Cub Cadet, or Husqvarna riding mower with a 5/16"-18 threaded axle and need a simple, low-cost replacement for worn or missing wheel fasteners, this set is a solid choice. It’s not for heavy-duty commercial use or metric systems, but for a quick homeowner fix, it works well.
