button head screw BA 28 3.5 by 25 mm

[spykelly420]

does anybody know how to correctlu put in these screws,l there more like hex bolts but super shallow, on the rear the bottom 2 screws r 2.5 mm hw

ex w a deep inset and tapered head or flush, the tops r the buttons i am heving trouble w. the bottoms r the flush n go in nice. then i looked at the front diff and its held in by all button head BA #28s. AM I using the wrong tool? I have been trying to use a hex wrench. I get half way in and it starts slipping out the tool for the inset is extremley shallow not allowing rhe tool to get much torque I believe.

I've used button heads many times with no problems .Not to sound patronising but,I assume you are using the correct size of hex. driver ,Are the threads already cut in? , if not you could use a 3.5 bolt to cut it or a 3.5 tap then use the button head , but this shouldn't be neccessary .Are the bolts made properly as it's not uncommon for the bolt to be made too shallow in the head drive. You could also try a torx driver of the correct size
