They have the correct head and thread size for Japanese motorcycles but are A2 stainless steel so will not rust.
Please remember to use some anti-seize lubricant, like copper grease, to ensure the screws come out as easy as they went on.
If you are not 100% happy with your pack then you can return for a full refund but please message me 1st before returning! No questions asked!
Thanks for looking!
