When you’re running a sickle bar mower through heavy grass or tough cutting conditions, you need every bolt holding tight. These countersunk bolts and nuts are specifically designed for New Holland twin sickle assemblies, where proper fastener alignment matters for smooth operation and reliable cutting performance. The countersunk head sits flush with the sickle section, reducing snags and maintaining the clean cutting action your mower was designed for.

Built for Cutting Season
These fasteners are designed for the demanding world of hay and forage cutting where sickle bars take a beating from rocks, stumps, and thick-stemmed crops. Twin sickle systems depend on precise timing and secure mounting to maintain their aggressive cutting action, and these bolts keep everything locked in place through thousands of cutting cycles.
Made to Last
Sickle bar hardware faces constant vibration, impact loads, and the occasional rock strike that can loosen inferior fasteners. These bolts are built with the strength to handle the shock loads while the precise threading ensures they’ll tighten properly and stay put through long cutting sessions.
Good to Know
Keep a few extra sets in your toolbox during cutting season – when you hit a hidden fence post or rock pile, having the right hardware on hand gets you back to cutting fast. The countersunk design means these won’t work on standard sickle sections, so make sure you’re ordering the right style for your specific sickle assembly.
