Description
When you’re dealing with a loose or broken rim-to-disc bolt on your tractor wheel, it’s not just about the bolt—it’s about keeping that wheel properly secured when you’ve got important work to do. This M16 x 93mm square-head bolt is designed specifically for those older tractor wheels that use a square drive system instead of hex heads. You’ll appreciate having the right bolt that actually fits the way it should.
What You’re Getting
- M16 x 93mm metric threading that matches factory specifications exactly
- Square head design grips properly with square-drive tools—no rounding off like hex heads can
- Heavy-duty construction that handles the stress and vibration of field work
- Direct replacement for worn or damaged rim bolts on multiple tractor brands
Built for Real Farm Work
This bolt fits a wide range of tractors from Massey Ferguson’s 200, 300, 600, and 4200 series, along with Ford New Holland models from the 10 series up through the 700 series. Whether you’re running a compact utility tractor or a bigger row-crop machine, these are the tractors that handle everything from loader work to heavy tillage operations where wheel integrity really matters.
Made to Last
Farm equipment bolts take a beating from constant vibration, temperature changes, and the stress of carrying heavy loads across rough ground. This bolt is built with the proper metallurgy to handle those conditions without stretching, cracking, or working loose over time.
Installation Notes
This is a direct replacement that threads right in without modifications. You’ll need the matching M16 nyloc nut (QTP-1996) and flat washer (353774) to complete the assembly. A quick tip: clean the threads on both the bolt and rim hole before installation—debris or corrosion can prevent proper torquing and lead to loose wheels down the road.
