Cup Head Bolt

The rounded top of the cup head bolt does not exert excessive pressure on the surface, so it will not scratch or dent delicate parts, while still firmly fixing the connection, comfortable to use and beautiful.

Features

Cup head bolts have a wide flat section under the head, and they also spread the weight evenly, preventing pressure buildup and keeping the joint stable.You can use regular tools to tighten them, even in tight spots, and they work with washers or lock nuts for extra security.

For industries that value safety and part durability, cup head bolts are affordable, reliable, and meet important standards such as ISO, ASTM, and DIN.

We can tweak cup head bolts to fit any project,and can even make bolts with different thread types, like left-handed threads.

You can also get bolts with built-in washers or holes for safety wires. Engineers use 3D models to test designs before mass production, making sure they fit perfectly in complex machines. For specific industries like oil and gas, there are special certifications available too.

FAQ

Q: Can cup head bolts be customized for non-standard sizes or materials?

A: Absolutely! We’re experts at making custom cup head bolts. We can do custom diameters (like M5 to M36), extra-long lengths up to 500mm, and even use special metals like titanium or Hastelloy® for super-tough situations. You can also choose thread styles (like left-handed or fine threads) or add marks on the head for tracking.

For example, 316L stainless steel bolts are perfect for ocean environments, while heat-treated alloy steel works great in high-temperature machines. We use prototyping and 3D modeling to make sure the design is right before mass production. Every custom bolt comes with complete paperwork – material certifications, size reports, and more.
