12pcs x M8 x 10mm Black Nylon Spacers and Standoff Washers for M3, M4, M5, M6, M8 Screws, Lengths 3mm to 30mm

Nothing to dislike about them. I used them to hang down pipe brackets on an uneven stone wall perfect

Fast delivery and used everyone. Good Quality product just what I needed.

I honestly haven't got a clue what these SPACERS / WASHERY THINGS are supposed to be used for,But, I have a drum, specifically a 16" floor tom made by Sonor if you're interested.I decided a while back to convert this drum into a bass drum for an "I-can-play-this-with-a-small-bass-drum-in-just-about-any-tight-corner-in-a-pub-once-this-pandemic-is-over" kit.Tension bolts, being highly engineered German lumps of metal wouldn't be the right size or length would they? No; the standard bolts that came with the floor tom are way too short, when I factor in a 3 cm deep maple hoop against a chrome 'triple-flanged' hoop {Triple-flange hoops allow drums to resonate more fully than other types, and they aren't very heavy. They improve rigidity, but mute the drum slightly because of the additional mass} ( I bet you didn't think you'd be reading the term "triple flanged" today, did you?!) anyway, the tension bolts I purchased were a touch too long, I'm a drummer not an engineer, so the selection of some kind of spacer was required - enter "Black Nylon SPACERS Plastic Standoff Washers (Pack of 12) (M6 / 6mm, 15mm)" - they have done the job perfectly and while tightening the 'reso' - resonant or front - head, ( you're not only acquiring knowledge about a silly word - "triple flanged!" but a knowledge of drum head replacement too ) the SPACERS have stood up to extreme tightening. They also look pretty cool against the bass drum hoop........Anyway, if you've lasted this long reading to this point- congratulations - I gave up and left the room half an hour ago; stay safe during this pandemic, take care.

Ok

Did the job well and helped me straighten up my wonky gazebo

I used these as a spacer when fitting a rear luggage rack on a motorbike. The rack was in danger of hitting the brake caliper on compression of the suspension, so I put these spacers in to move the luggage rack out 25mm. Looks like a professional job! The spacers are very strong and durable. I sandwiched them between two flat washers and even with quite a high torque setting they don't distort. I've since found a variety of uses for these.

Perfect for adjusting downpipe when it can't sit flush to wall. Easy with a small hacksaw to get the exact size if you need to adjust from what they are

Good
