Full listing title: Husqvarna Shear Bolts & Nuts Kit for 2 Stage Snow Blowers/Throwers (6 Pack) 570XP, 575XP, 576XP/ 580790401, 588077502, 539976978, 595086601
Two shear pin kits close to it on our rating, each with a dated price.
The count the listing states, part 580790401. Enough for a season or two of frozen newspapers, if you tape a couple to the handle. When one snaps mid-storm, the fix is a pin out of the bag and five cold minutes.
What it has going for it
6 pins. They are meant to snap when the auger hits a frozen newspaper or a chunk of ice, so the gearbox doesn't. Spares taped to the handle turn a ruined morning into a five-minute fix.
The listing names part 580790401.
Shear pins are sized to the hole in the auger shaft and made to snap at a set load. Use the part number from your manual; a hardware-store bolt won't break when it should, and the gearbox pays.

Our take
The Husqvarna Shear Bolts & Nuts (6-Pack) is about 6 spare bolts, and it doesn't pretend to be more. No buyer reviews yet, so the Husqvarna Shear Bolts & Nuts (6-Pack) has to win you over on paper. Honestly, the catch: no word on the exact machines it fits. We'd pick it if you want spare pins in the garage before the storm, not after; otherwise, put it next to the YAMAKATO 738-04124A Shear Pins (6) first.
Before you order the Husqvarna Shear Bolts & Nuts (6-Pack), check your model number: it is sold as part 580790401, and fit is model-specific.
Look for the plate on the frame, usually under the handle or behind the engine, and copy the model and serial numbers into your phone.
Never swap in an ordinary bolt: the whole point is that the pin breaks before the gearbox does. Our shear pin guide shows how to change one.
Parts are easy to fit in a dry garage and miserable mid-storm. Our parts guide lists what is worth stocking.
