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

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.

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

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

These are extremely thin they are not much bigger than the M4 screws that go through them. I dont feel comfortable mounting anything with these.

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.

Spacers used to repair a rowing machine, worked perfectly.

Are what they are well sized and produced
