Oval Head Section Rivets for Knife Head Assemblies and Mower Bar Sections

Description

If you’ve ever worked on a mower bar or knife head assembly, you know that loose or missing rivets can turn a good cutting day into a frustrating mess. These #5-1/2 (.211″ diameter) oval head rivets are specifically designed for use in sections where you need a strong, reliable connection that’ll hold up to the constant vibration and stress of field work. When your knife sections start coming apart, these are the rivets that’ll get you back to cutting clean.

What You’re Getting

• Perfect size for most mower section applications – #5-1/2 diameter (.211″) fits standard section holes without being loose or tight
• 1-inch length gives you enough material to form a solid connection on both sides of the section
• Oval head design spreads the load better than round heads, reducing stress on the section material
• Box of approximately 90 rivets – enough to handle multiple section repairs or a complete knife rebuild

Built for Real Farm Work

These rivets are commonly used on hay mower knives and cutter bar assemblies across many different tractor brands. Whether you’re rebuilding sections on a disc mower, sickle bar, or other cutting equipment, the consistent .211″ diameter and 1″ length make these rivets versatile enough for most applications. They work well on both light-duty and heavy-duty cutting equipment.

Made to Last

Farm equipment rivets take a beating from constant flexing, vibration, and the impact of hitting rocks and stumps. These oval head rivets are manufactured to handle those stresses without loosening or breaking. The oval head shape distributes forces more evenly than standard round heads, which helps prevent the rivet from pulling through the section material over time.

Installation Notes

These are solid rivets that require a rivet gun or hammer and bucking bar to install properly. Make sure your rivet holes are clean and free of old rivet material before installation. A quick tip from the shop: if you’re doing a lot of sections, it’s worth investing in a good pneumatic rivet gun – it’ll save your arm and give you more consistent results than trying to buck them all by hand.
