Built for Real Farm Work
These cap screws are sized for the kind of heavy-duty connections you’ll find on combines, planters, cultivators, and other large implements. The 7/8 inch diameter handles serious loads without stretching or failing, while the 3-inch length gives you flexibility for thicker materials or when you need extra thread engagement.
Made to Last
The zinc plating protects against the rust and corrosion that comes with exposure to fertilizers, moisture, and road salt. This coating holds up better than plain steel and gives you more life between replacements, even when hardware gets splashed with hydraulic fluid or sits in weather between seasons.
Good to Know
Always use the right size wrench – 1-5/16 inch for the hex head – to avoid rounding off the corners. When replacing hardware, check that threads aren’t damaged or cross-threaded before tightening. A drop of thread locker helps prevent vibration loosening on critical connections, especially on equipment that sees a lot of road time.
