90105-VA3-J01 10x25mm HEX Bolt and 90502-VG3-000 10mm Washer Set Compatible with Honda HRX217 HRS216 HRR216 Lawn Mower, Replacement 304 Stainless Steel Blade Bolt Set for Honda (2 Pack)

What It Is

This is a genuine Honda OEM replacement blade bolt and washer set (2 pack) designed to secure the cutting blade to the spindle on Honda HRX217, HRS216, and HRR216 lawn mowers. It includes two 10x25mm hex bolts and two 10mm flat washers, made from 304 stainless steel for corrosion resistance.

Fitment & Compatibility

Check your mower’s model number (on the engine cowl or frame) to confirm it’s one of these: HRX217, HRS216, or HRR216 series (any sub-model, e.g., HRX217HYA, HRR216K9). The bolt is 10mm diameter, 25mm long, with a 10mm hex head. The washer is 10mm ID. This set replaces OEM Honda part numbers 90105-VA3-J01 (bolt) and 90502-VG3-000 (washer). It will not fit most other brands (Toro, Craftsman, etc.) unless they use the same Honda-style spindle. Measure your existing bolt length—if it’s longer than 25mm, this set won’t work.

Key Things to Know

• Stainless steel vs. standard steel: 304 stainless resists rust better but is slightly softer; torque to manufacturer spec (typically 30-35 ft-lbs) to avoid stripping.
• Installation is straightforward: Use a 10mm socket or wrench. No thread locker needed—the bolt has a built-in lock washer feature on the underside.
• Common gotcha: If your old bolt is seized, use penetrating oil and a breaker bar. Replacing both bolts at once ensures even torque.
• Only 1 review: At 5.0 stars, it’s promising but limited data. Honda OEM parts are generally reliable, but the stainless variant is less common than the zinc-plated original.

Should You Buy It

Buy this if you own a Honda HRX217, HRS216, or HRR216 and need a rust-resistant blade bolt set that matches OEM dimensions exactly. It’s ideal for coastal or high-humidity areas where standard bolts corrode quickly. Avoid if your mower uses a different bolt length or thread pitch—stick with the original Honda part number for guaranteed fit.
