M8-1.25 (25 pcs) Serrated Flange Hex Nuts, Hexagon Flange Nuts 304 Stainless Steel 18-8, Bright Finish, Full Thread, DIN6923

These things are great! Used them to replace some rusty nuts on my fuel pump. No stripping and the finish seems pretty durable. Definitely recommend if you need some extra nuts and bolts for a project. Five stars for sure!

OEM Toyota flange pinch hex nuts were going for $8 each to mount 4 of these to replace 2 oxygen sensors on my 1999 Toyota 4runner. These are great alternative & value for 1/4 the cost & get 25 flange hex nuts! These are great quality in replacing my 23 year old brittle rusted oxygen sensor nuts.

I own a 2013 Mercedes S550 Base W221, and I had to remove the tail lights to replace the light bulbs inside. I never thought that these tail lights would use such small-sized nuts to hold them in place. It takes 3 of them per side, so when I went to install them back, I lost 2 of the nuts. I came to Amazon looking for replacements, and this pack popped up when I entered the description, M5x0.8mm. I ended up buying 100 nuts for the price of a single Mercedes Benz branded one, and these are better than the OEM ones. I can't recommend these enough!

I didn't need anywhere near 50 of them.I used these and matching allthread rod to replace the long Honda carburetor bolts on a mower. With those Honda bolts, it is very hard to slide 7 or 8 items onto the bolts and then install those bolts. Now, I cut rod studs and installed them on the engine. Then just slide all of the parts onto the 2 studs and screws these nuts on.

Product as described and pictured. Priced well

Excellent fit.

My bad. Great product.

With the flaange nut you get a wider contact surface and I've not needed lock washers
