12pcs x M8 x 30mmBlack Nylon Spacers and Standoff Washers for M3, M4, M5, M6, M8 Screws, Lengths 3mm to 30mm (Pack of 12)

Not sure what these are meant for but screws were too long on a bedside cabinet so used these rather than sawing the screws down. Worked perfectly.

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.

Not much to be said really - plastic spacers, even sized, good strong construction. I'd say for what they are, expensive but they did the job.

As described

Worked well for the task needed

Brilliant set of various standoffs if you need to place them in bolts to take the play out

Worked a treat,as the spacers were ideal for the conduit spring clips to keep it level between the fence and the fence posts

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