Where a snow blower square neck bolt m8x18 fits
Vibration is the enemy here. What holds through a summer of mowing does not necessarily hold through a February of clearing ridge ice. The cheapest way to ruin an aluminium casting is to run a near enough fastener into it and lean on the spanner.

Signs it has reached the end
There is a short list of symptoms here, and most owners recognise at least one of them.
- a joint that will not stay tight through a season
- a rounded or stripped head left by an earlier repair
- vibration that appeared after work was done nearby
- visible corrosion at the thread or under the head
- a fastener that turns without tightening
They fail from corrosion and from being reused too often, not from age. There is no price advantage in waiting and there is a real availability cost.
Fitting it
Isolate the machine before you start. Nothing on this job needs the engine turning. Lay the fasteners out in the order they came off. Outdoor power equipment uses more thread sizes in one assembly than people expect.
Match pitch and length exactly. A bolt ten millimetres too long bottoms out and feels tight while the joint is still loose. Compare both parts side by side first, particularly length and hole spacing.
Clear blockages with the tool, never with a glove, and never with the engine merely idling. The same rule applies whenever the auger housing is open.
Buying, shipping and returns
At $6.97 Canadian, this sits where you would expect for the class. Anything of this size posts normally, and the free freight threshold is $999. shipping and delivery has the detail.

Use the contact page if you want a second opinion before ordering. Consumer rights when buying a snow blower square neck bolt m8x18 in Canada, above any retailer policy, are set out by Consumer Protection Ontario.
Identifying the correct component
If you are cross referencing an old component, compare the stamping against 303020166 before ordering. Model names persist for years while the components underneath them do not.
Use a thread locker only where the manual asks for it, and never on a nylon insert nut. Count the threads showing on the original and match them on the replacement.
Where to find the stamped number on each part is covered in the snow blower repair guide. Give us the model and serial from the machine plate and the identification takes minutes rather than days.
Canadian winters and this part
Canada is not one snow market. In the Ontario and Quebec corridor the pattern is moderate depth with the plow ridge as the deciding factor. Late summer through October is when choice is widest across the whole catalogue.
Freight across the country slows once the first storms arrive, so autumn is when a spare actually reaches you quickly. Thirty year normals for your own station are published free by Environment and Climate Change Canada.

Reading the listing
The distinguishing terms here are square, neck, bolt. Left and right are not interchangeable even when the castings appear symmetrical.
This line is 303020166. Thread size M8 by 18 mm is exact and the adjacent sizes will not thread correctly. Quote it exactly and the right item arrives first time.
What else to check
A repair is cheapest when everything that needs doing is done at the same time. Have a look at the covers and guards for cracks too. Now is the moment to inspect the seals at every shaft exit. Add the bearings for play and roughness to the same inspection.
None of those are expensive, and snow blower parts has them by number. the maintenance checklist sets out the seasonal order to work through them in, and the snow blower repair guide covers what to do when one of them turns out to be the real fault.
The autumn order
Most emergency repairs are emergencies only because the part was not already in the garage. A belt, a pack of shear pins, a set of auger paddles on a single stage machine and a spare scraper bar cover almost every in season failure.
Everything on that list is on snow blower parts, searchable by the number stamped on the old component rather than by machine name. The parts everybody wants in February are the parts that are slowest to arrive in February. A pallet or a length of timber under the machine over summer is the cheapest rust prevention there is.

Common questions
Does fitting this affect my warranty?
Fitting a correct replacement part does not void a manufacturer warranty. Consumables were never covered in the first place.
How long should it last?
Indefinite, until somebody puts the wrong tool on the head.
What else should I check while it is apart?
Whatever the component touches. Bearings, seals, fasteners and belts are cheap while the assembly is open and expensive once it is closed.
Will you check the fitment for me?
Yes. Send the machine model, the serial number and a photograph of the old part through the contact page and we will confirm in writing before anything ships.
Is a generic equivalent acceptable?
Sometimes, and often not. Pitch, grade, profile and length are all specified. Where a genuine part is unavailable we will say so rather than sell you a guess.
How do I know this fits my machine?
Order by stock number 303020166. The same model frequently ships with different components across production years, so the stamped number is the only reliable identifier.
