80058118 Knotter Shear Bolt and Nut Fits New Holland Square Balers

One new aftermarket knotter shear bolt with lock nut.

This is the sacrificial shear bolt on the knotter and twister drive of a small square baler. It is designed to shear and break if the knotter or twister jams, which protects the knotter, the needles and the drive. It is a wear part.

It is about a number 12 thread, 1 1/2 inch long, with a reduced shear shank near 0.210 inch, and it comes with a flanged lock nut.

Made to fit New Holland small square balers that use the twine knotter, such as the 268, 269, 273, 275, 277, 280, 282, 310, 315, 320, 420 and 426. It crosses to 58118 and now supersedes to 86578266. Use a shear grade bolt only, not a hardware store bolt.
