fnaguitarplayer9 I always appreciate your videos - it's clear you put a lot of work into both shooting and editing them, and they are extremely informative! Keep on doing what you're doing! I've definitely learned a ton on working with small engines from your tips

[fnaguitarplayer]

oh wow! definitely didn't know that!!! and i never heard of a grade 3 bolt! thanks for the info! thanks for watching!!!

[fnaguitarplayer]

i hear ya. i love brass! i have some brass wood screws and brass machine screws but no bolts. thanks for watching!!!

[fnaguitarplayer]

Hey Frank, Just a little FYI...If you have no idea of the quality of a piece of steel you can very lightly grind it in a bench grinder. Try to do it in a shadowy or dark area of your shop. The HIGHER the grade of steel alloy it is made of, the finer the sparks that come off of it will be. Granted, there are lots of variables like coatings and hardness. Try it out with a few pieces of KNOWN quality steel. The difference is amazing. Junk steel makes coarse sparks. Quality steel is fine sparks!

Thats a good idea, never thought of that! I'll have to try that sometime! Thanks for Watching!!!

I like brass bolts. I use them to hold exhaust on mower engines. They don't seem to seize-up with the extreme heat

[fnaguitarplayer]

I've always wondered why they mark a grade 2 with no marks, a grade 5 with 3 marks and a grade 8 with 5 marks. Its so weird. Great video!!!!

[fnaguitarplayer]

butter bolts haha thanks for watching!!!

[fnaguitarplayer]

that would work! didn't think of that!!! haha

thats a common misconception about the grade 8 bolts that there yellow heck i even thought that actually you can get grade five in yellow zinc its just more common of a coating LOL mtd is now getting there grade 5 bolts in the yellow zinc to make the products look stronger also there is a grade 3 bolt that has 2 dashes .. normaly there is there 3 dashes + 2 e grd 5 6+2 grd 8
cheers

Thanks for the information. I was thinking about looking for a video like this and just stumbled on this one. Do you know of situations with small engines or anything else where it could be beneficial to upgrade or downgrade the bolt types from the factory type? Thanks.

CORRECTION #1: Grade 5 = Class 8.8, Grade 8 = Class 10.9. Class 12.9 & 14.9 are much stronger than Grade 8.

CRRECTION #2: Grade 8 bolts are usually better than grade 5 bolts even when bending is concerned because even though grade 8 bolts are more brittle, they're still usually in the bending stage by the time a grade 5 bolt would have snapped already.

Slightly frustrated with the amount of I don't knows in this video. Take a few seconds and research things cause I now gotta find another video. Would have been easier if I was told everything now in this video.
