18Sizes 450Pcs Car Engine Oil Drains Plug Aluminum Washer Gasket Nut Bolt Set Sealing Ring O Rings Kit Set Smile Home

Add the eighteen rows of this size table up and they come to 450, which is exactly the number on the packing line. Six rows carry forty washers each, nine carry twenty and three carry ten. That is worth saying because assortment listings usually do not survive the arithmetic, and this one does. Inner diameters run from 6 mm to 24 mm and outer diameters from 10 mm to 29 mm, so the spread is wide enough to be genuinely useful in a drawer.

What the supplier says these washers are for

The whole purpose sits in a single sentence, and that sentence disagrees with the heading. The gasket, says the supplier, keeps the nut from working loose, and the set is meant for machinery that runs under a vibration load. That is an anti-vibration fastener washer. It sits between a nut and its face and takes up the small movement that would otherwise back the nut off. Nothing in the description ever describes it doing any other job.

The table adds up, and one row does not

Seventeen of the eighteen rows carry a sensible thickness: 1.0 mm on the smaller bores, 1.5 mm across most of the middle and 2.0 mm on the largest. The exception is the sixth row down, which has lost a character out of its thickness figure, and a second line elsewhere in the description has lost one from the same column. We publish neither damaged figure and we have mended neither of them; guessing at a washer thickness is how a fastener ends up under-clamped.

Key features

• Eighteen rows, 450 washers: the size table and the pack total agree with each other when you add them up.
• Six, nine and three: six of the rows hold forty pieces, nine hold twenty and three hold ten.
• Inner diameters 6 to 24 mm: the bores step up in twos across the range.
• Outer diameters 10 to 29 mm: most bores are offered in two outer sizes, so there is some choice of bearing face.
• What the supplier says they do: stop a nut loosening on machinery that works under vibration.
• The plastic box: a storage box is described twice, though it is not itemised in the contents.

Specifications

• Total pieces: 450
• Sizes in the table: 18
• Aluminium, ungraded: aluminium, with no alloy designation given
• Bore range: 6 mm to 24 mm
• Outside range: 10 mm to 29 mm

The gap between the heading and the description

• Read the heading, or the short summary sitting under it, and you are being sold engine oil drain plug crush seals and O-rings. The description says none of that. Not once does it use the words oil, drain, plug, engine, sealing or O-ring, and the sole purpose it offers is stopping a nut vibrating loose. If you came here for a sump washer, ask the seller outright whether these will crush and seal, because nobody has written it down here.
• The heading also promises a nut and bolt set. The contents line is 450 gaskets and nothing else. No nuts, no bolts.
• The thickness figure is damaged in two separate places. Neither version is published above, and no reconstruction has been attempted from the rows around them.
• The listing qualifies its own numbers as hand-taken and slightly variable, an allowance that matters more against a 1.0 mm thickness than against a 24 mm bore.
• The plastic box appears in the description twice and is missing from the contents list. Treat it as unconfirmed.
• Five things you would want are missing outright: a torque figure, a temperature range, a pressure rating, an alloy designation, and a hardness or temper. For anything sealing a fluid under pressure that is the material gap, which is one more reason to believe the job the description gives them.
• One of the supplier's material sentences has lost a word and reads as a repetition. It is not quoted here.

Read this as a drawer full of ungraded aluminium washers for holding nuts still, sized generously and counted honestly, and take the sealing story in the heading as unsupported until somebody puts it in the description.
