Red face Oster Blender Screw HELP!

Hi all, a newbie here from India. I have been using an Oster Blender model# 869-50R since 30+ years now. I got it from Singapore back then. It was just recently that the blender needed a part replacement, which I have identified and the said part is available on amazon, but it is the 3x screws underneath the blender base\body that I am unable to identify and hence open. I am enclosing a close-up of the screw, if anyone on here can help me identify the said screw so that I can look for an apt screw driver to open it. I am also enclosing a clear picture of the entire blender body base for reference, which will show all the 3x screws on it. Please reply if anyone is aware of these screws. Much appreciate any inputs and thanks in advance.

Not completely sure, but those are tamper resistant heads, and a tri groove bit might be what you need to remove them. Perhaps similar to this.

Thanks for the input! Seems like I have inched a bit closer to what it is, but still havent got there.. I see the screw setter you have referred to, but I think it is not EXACTLY useful in my case... If anyone else has any info as to what this screw head is precisely known as, please chime in...

I don't think that is a screw - nor do i think it is meant to be removed. It looks to me like a 3-prong shaft locking retainer clip made of spring steel - some may call it a shaft locking washer - that is pressed onto the shaft and prevents the shaft from coming out of its chase. It also appears the clip fits tightly against the chase wall which keeps the shaft perfectly centered in-place.

I'm not sure why you would even want to remove this. I guess the OE retainer washer/clip could be pried off somehow, however if might be next to impossible to force a new retainer/washer clip onto the shaft because the shaft would probably move/slide away when a new clip is attempted to be forced onto it - as the shaft would not be held steady or firmly enough that enough force could be used to press on a new shaft washer/clip.

Somewhat similar to this type of press-on washer/clip fastener:

Thanks for the reply. But just to clarify, i had this blender repaired by a local oster service centre some 10 years ago for a mechanical part change and it was these 3x exact screws that they had opened. But now the service centre has closed down and the same mechanical parts need to be changed, which are easily available on amazon, but its just that i need to open these screws to be able to change it.

Hence I am sure these are screws that can pretty much be opened.

No chance of twisting them with needle-nose pliers? Maybe super glue a small bolt or screw on it to turn?

Just trying to think outside the box.

Thanks for that clarification. That helps identify them as being threaded onto a threaded bolt or shaft instead of being pressed on like a spring-steel clip fastener.

If those 3-prong fasteners are not pressed on a shaft - but instead are threaded onto a threaded bolt/shaft - then as the_tow_guy suggested, you should be able to use a pair of needle-nose pliers to turn and unscrew it (just like a nut) from the threaded bolt/shaft.

Even better, if you have access to a pair of locking clamp pliers (like pictured below), that would help maintain a grip on the 3-prong fastener whereas a pair of needle-nose pliers might be more difficult to manage.

Could also try to find a flat blade screw driver or piece of flat steel that will just fit into screw cavity between 4 and 8 o'clock in the first photo. This should allow engaging the edge of 2 of the 3 grooves in the screw head. Guessing the threads are right handed.

Have a question after revisiting the first photo. Are the 3 shiny areas, that include the outside diameter of the screw head, above or below the area formed by the 3 slots?

That's basically the same/similar bit that I posted 3 months ago which you decided wasn't useful and didn't try.

The screw driver tip in post 12 is a shape that should work. The tip's OD and depth of bore should match the screw head as close as possible.
