Sockets for square drive torque wrench

Product catalog summary

Specifications:

The sockets are manufactured from high-strength Cr Mo alloy steel, ensuring durability and reliability.
They undergo a standard heat treatment process for enhanced safety and performance.
Customization is available for non-standard sockets.
Heavy-duty sockets conform to DIN3121/3129 standards.

Socket Types:

Single cap socket
Double cap socket
Outer hexagonal socket LFB
Outer hexagonal socket F

Torque Recommendations:

The chart provides maximum recommended torque values for bolts, measured at 60% of the bolt's yield limit.
The recommended tightening torque is 70-80% of the chart values. For example, for an M52 grade 8.8 bolt, the tightening torque should be between 4453-5090Nm.
The loosening torque should be 1.5-2.5 times the tightening torque.

Strength Grades and Materials:

Strength grades range from 4.8 to 12.9, with minimum breaking strengths from 400MPa to 1200MPa.
Materials include general structural steel, mechanical construction steel, chrome molybdenum alloy steel, and Ni-Cr-Mo alloy steel.

Torque Values:

The document provides a detailed table of torque values for various bolt sizes and strength grades, expressed in both KGM and NM.
For example, an M16 bolt with a strength grade of 4.8 has a torque value of 87NM, while a grade 12.9 bolt of the same size has a torque value of 294NM.
