Explosion-proof technical requirements for socket wrenches:
The production certification materials for socket wrenches should use the national standard: bronze, aluminum bronze alloy. There are two strength levels of GB F wrenches: C-level and D-level.
Common specifications are generally: 250 -1000MM.
Quality requirements for explosion-proof F wrenches:
1. The surface must be smooth and free of burrs. The shank is a chamfered end; the working end is symmetrical parallel to the straight front paw. Cortex and no oxidation, no cracks, scabs, and blisters.
3. The corresponding national standard hardness is required.
4. Relevant national regulations are required, the torque is unloaded, the two ends of the working claw can not be deformed, cracks and other damage to the strength of the experimental torque.
5. The performance of the socket wrench will reach the national standard GB/T10686.
