Genuine 304 Stainless Steel Blade Bolt Set for Honda HRX217/HRS216/HRR216-10x25mm HEX Bolt 90105-VA3-J01 & 10mm Washer 90502-VG3-000 (2-Pack)

What It Is

This is a genuine Honda 2-pack blade bolt and washer set (bolt 90105-VA3-J01, washer 90502-VG3-000) designed to secure the blade to the crankshaft on select Honda walk-behind mowers. It’s a direct OEM replacement for HRX217, HRS216, and HRR216 models, made from 304 stainless steel to resist rust and corrosion.

Fitment & Compatibility

Before buying, confirm your mower uses a 10mm x 25mm hex bolt with a 10mm washer. This set fits these Honda series:

• HRX217 (all variants, including VKA, VLA, VYA, TDA, etc.)
• HRS216 (all variants)
• HRR216 (all variants, including VKA, VLA, etc.)

Check your model number on the mower’s data plate (under the rear flap or near the handle). This bolt is not for Honda mowers with a 5/16″ or 12mm bolt, or for non-Honda brands like Toro, Craftsman, or John Deere. If you have an aftermarket blade adapter, verify the bolt hole is 10mm—some aftermarket adapters use a different thread pitch.

Measure your current bolt: length should be 25mm (about 1 inch) from under the head to the tip. If yours is shorter or longer, this won’t fit.

Key Things to Know

• Material matters: 304 stainless steel won’t rust like standard steel bolts, but it’s slightly softer—use a torque wrench to avoid stripping. Torque to 35-40 ft-lbs (Honda spec).
• Installation tip: Apply a drop of medium-strength thread locker (blue Loctite) to prevent loosening from vibration. Do not overtighten.
• Common gotcha: The washer is a specific 10mm ID flat washer—don’t substitute a lock washer or a different size. The bolt head is 10mm hex, so you’ll need a 10mm socket or wrench.
• Pack includes: 2 bolts and 2 washers—enough for one mower with a spare, or two mowers if you have a matching pair.

Should You Buy It

Buy this if you own a Honda HRX217, HRS216, or HRR216 and need a corrosion-resistant, OEM-spec blade bolt set—especially if you live in a humid climate or store your mower outside. It’s a no-brainer for $12.99 if your current bolts are rusted or stripped. Skip it for non-Honda mowers or if your bolt size differs.
