- 7/16 UNF Grade 8.8 with 14mm head -

This concerns a set of the bolt (length thread 35 MM), nut and associated washers.


*********

This is a set of the bolt (length thread 14 MM) , nut and associated washers.

The torque of an M11\*1.25 fastener is 48 N.m.

Explanation:

• M11: This indicates the fastener is metric and has a nominal diameter of 11 millimeters. 
• 1.25: This represents the pitch, or the distance between each thread. 
• 48 N.m: This is the tightening torque, which is the force required to properly tighten the fastener. It's measured in Newton-meters. 

In summary, the torque value of 48 N.m is the recommended force to tighten an M11 fastener with a 1.25 pitch.
