4 Pack 137644 193406 Wheel Bolts and Lock Nuts fits Cub Cadet Craftsman Husqvarna 137644 193406 532193406 184219 532137644 738-3056 938-3056 73930600

What It Is

This is a set of four wheel bolts and matching lock nuts (part numbers 137644, 193406, and cross-references) designed to secure lawn mower wheels to the axle. It’s a direct replacement for many Cub Cadet, Craftsman, and Husqvarna riding mowers and zero-turn models.

Fitment & Compatibility

Before buying, check your mower’s original part number. This set replaces OEM numbers 137644, 193406, 532137644, 532193406, 184219, 738-3056, 938-3056, and 73930600. It fits most Cub Cadet, Craftsman, and Husqvarna models with a 3/8‑inch wheel stud and a standard 5/8‑inch hex head. Measure your existing bolt length: these are about 1.5 inches long. If your mower uses a different thread pitch (fine vs. coarse) or a flange-style nut, this set won’t work. Always verify your mower’s deck size and model year—this kit is common on 42‑ to 54‑inch decks.

Key Things to Know

• Quality: Zinc-plated steel resists rust, but avoid overtightening—stripped threads are a common failure.
• Installation: Easy DIY job. Use a 5/8‑inch socket and torque to 30–35 ft-lbs. No special tools needed.
• Common gotcha: The lock nuts are nylon-insert type—do not reuse them after removal. Always replace with new nuts for safety.
• Cross-reference: Works with many aftermarket wheels too, but confirm your wheel’s center hole diameter (typically 0.5 inches) matches the bolt shank.

Should You Buy It

If your Cub Cadet, Craftsman, or Husqvarna riding mower uses these specific bolts and you need a reliable, affordable replacement set, this is a solid buy. It’s ideal for replacing worn or missing hardware during wheel removal, flat repair, or routine maintenance. Avoid it if your mower uses metric fasteners or a different bolt head size.
