M60 nut dimensions or sizes are critical for massive hydraulic press assembly, heavy bridge girder anchoring, and large-scale industrial turbine mounting. This size is specifically engineered to mate with fasteners having a 60.00 mm nominal diameter and is commonly available in M60 x 5.5 for the coarse series.
This charts is based on the Regular Series (DIN 934 / ISO 4032) for standard load-bearing applications and the Thin or Half Series (DIN 439 / ISO 4035), which is ideal for jam nut or lock nut configurations or applications with limited vertical clearance. The thread dimensions comply with DIN 13-1 (coarse) and ISO 68-1 standards to ensure a precise fit and reliable engagement across extreme-capacity industrial metric fastening systems.
Disclaimer: Actual dimensions, including the width across flats (spanner or wrench size), nut height, and thread tolerance may vary depending on the specific manufacturing class and material — always verify with the official product datasheet before use or buying.
What size wrench or spanner do I need for an M60 nut?
An M60 hex nut typically requires a 90 mm wrench or socket. The standard width across flats (s) for an M60 nut is 90.00 mm. Given the massive torque levels required to properly tension an M60 bolt—often reaching several thousand kilonewtons—hydraulic bolt tensioning tools or heavy-duty planetary gear multipliers are essential for installation.
What is a jam nut?
A jam nut is a low-profile hex nut, typically from the Thin Series (DIN 439), that is used to lock a standard nut in place. By tightening a standard nut against a jam nut, you create internal tension between the threads of both nuts and the bolt. This “jams” the assembly together, providing a mechanical lock that prevents loosening caused by extreme vibration or high-cycle industrial loads.
Can a Thin Series nut handle the same torque as a Regular nut?
No. Because the Thin Series has significantly fewer threads in contact with the bolt, it has a lower proof load. For M60 fasteners, which are used in safety-critical industrial environments, using a thin nut as the primary fastener is dangerous as the threads are likely to strip or shear under the intense clamping force. Always use a Regular Series nut for primary load-bearing tasks.
