I would think a grade 8 bolt would do fine!

 

Grade 8 is a rating for SAE bolts. Metric bolts are measured in class, not grades.

A metric bolt with "8.8" written on it doesn't mean grade 8. It means class 8.8, which is roughly equivalent to a SAE grade 5.

Tricky, yes?

You need a metric, class 10.9 bolt. I can't remember if the factory bolt has a loose washer attached, or if its a flange bolt.

Either way, its a JIS, reduced wrench bolt.

Thread size M8x1.25 for the fronts. Should be about 16-20mm long.

Or just buy the factory bolt because its easy.

 

Thanks, it's a actually the seat belt buckle bolt that I'm after - you can't seem to buy it from honda unless you buy the whole buckle receiver too which is mad!

 

^Factory bolts had a flat washer and a split washer.

 

Thanks for the lesson.

 

No, you cannot buy a seat belt buckle bolt from a HW store.

Seat belt bolts are 7/16-20 SAE Grade 8 thread size. Which is commonly available, normally.

BUT...what makes them unavailable from a HW store is that they are a specific length, flanged shoulder bolt with a 14mm drive, which has to be assembled with all the washers exactly correctly.

Buy a used seat belt assembly or look for a part out that's selling the bolts.

I'm assuming you're using the stock seat belt receiver?

Seat belt bolts are a bit of an anomaly. They're always 7/16-20 SAE grade 8, due to a safety standard.

 

AH HA!! I was right then!

 

lol yes, I suppose you were
