Genuine Blade Bolt Set HRX217 HRS216 HRR216 HRN216 90105-VA3-J01,Replacement for Honda OEM, BLACK

What It Is

This is a set of four genuine Honda blade bolts (part number 90105-VA3-J01) designed to secure the blade(s) on select Honda HRX217, HRS216, HRR216, and HRN216 lawn mowers. Each bolt is black-finished and pre-coated with a thread-locking compound to prevent loosening during operation.

Fitment & Compatibility

Before buying, confirm your mower model and deck size. This bolt set fits Honda mowers with 21-inch or 22-inch decks from the HRX217, HRS216, HRR216, and HRN216 series. It is the OEM replacement for Honda part 90105-VA3-J01. Do not use on older Honda models (e.g., HR214 or HR215) or non-Honda mowers—thread pitch and length differ. Measure your existing bolt: this is M8 x 1.25 thread with a 25mm shank length. If your bolt is shorter, longer, or has a different thread pitch, it will not fit.

Key Things to Know

• Pre-locked thread: The factory-applied adhesive means you do not need to add thread-locker—just torque to spec (typically 30–35 ft-lbs). Over-tightening can strip the blade adapter.
• Always replace bolts: Honda recommends new bolts each time you install a new blade. Reusing old bolts increases the risk of loosening and blade detachment.
• Installation difficulty: Easy—requires a 12mm socket and torque wrench. No special tools needed, but a blade removal tool helps hold the blade still.
• Common gotcha: The black finish is cosmetic and wears off quickly. This does not affect performance. If you see rust, it’s normal; replace only if the bolt head is deformed or threads are damaged.

Should You Buy It

If you own a compatible Honda mower and are replacing the blades (or just need a fresh set of bolts for safety), this is the correct OEM part. The price is fair for genuine Honda hardware, and the pre-applied thread lock saves time. Skip it if your mower is not listed or if you are reusing old bolts—buy new ones instead.
