What is the reason for the locking of stainless steel fastener bolts?
What are the methods for tightening stainless steel fastener bolts?
1. Bolt torque method
Stamping and welding parts manufacturers use a universal wrench to initially tighten based on the relationship between torque M and preload force, and then use a specialized wrench with flashing torque values to tighten to the regular torque value.
2. Bolt angle method
The flange hexagonal bolt is a small method that can jointly explain the rotation angle of high-strength bolts after the pre tension interaction of stainless steel fastener bolts or double wig bolts.
When tightening the threaded rod and stud manufacturer, unscrew the nut from the short plate to the non rolling position, and then use a long wrench to tighten the nut to the regular position to achieve the pre tightening force.
3. Unscrew the bolt and remove the tail of the bolt
The manufacturer of threaded rods and bolts has a special top plate for high-strength bolts of stainless steel fasteners with torsional shear type. When tightening, use a special wrench to cover the bolt and bolt star.
Manufacturer of flange hexagonal bolts - one sleeve rotates forward and the other sleeve rotates. When the nut is tightened to a certain degree, the bolt fractures in a star shape.
Manufacturers of threaded rods and bolts allow the depth of the notch at the top of the bolt to be based on the relationship between the fracture torque and the pre tension of the stainless steel bolt. Therefore, when the bolt fractures, the corresponding pre tension value will be reached.
