Description
When you’re dealing with pulleys, sprockets, or coupling adjustments on your tractor, you need a set screw that’ll hold tight and stay put. This M16 x 45mm set screw is exactly what you need to secure those critical components that keep your equipment running smooth. Whether it’s locking a pulley to a shaft or holding a collar in place, this little fastener does the big job of keeping things where they belong.
What You’re Getting
- Heavy-duty M16 thread size that can handle serious clamping force without stripping
- 45mm length gives you plenty of bite for thick hubs and collars
- Coarse thread pattern grabs fast and holds strong, even with vibration
- Zinc and yellow plating resists rust and corrosion from field moisture and chemicals
- Hex socket head makes it easy to tighten with standard Allen wrenches
Built for Real Farm Work
This set screw is the type you’ll find throughout your tractor’s drivetrain and attachment systems. It’s perfect for securing PTO components, loader attachments, and implement drives where a collar or hub needs to stay locked to a shaft. The M16 size is common on mid-size to larger tractors where you need more holding power than smaller fasteners can provide.
Made to Last
The zinc and yellow coating isn’t just for looks—it’s a proven corrosion protection system that stands up to the harsh conditions farm equipment faces. This plating helps the screw resist seizing from rust, so you can actually remove it later when maintenance time comes around.
Good to Know
Always use the right size Allen wrench to avoid rounding out the socket head. A little anti-seize compound on the threads helps prevent galling and makes future removal easier. When tightening, snug it down firmly but don’t overtighten—you want to clamp the part securely without deforming the threads or the component you’re securing.
