Lshaped lag bolts
What are the advantages and disadvantages of black l shaped bolts, and what precautions should be taken when using them?
Advantages of black l shaped anchor bolts:
Lowest cost.
Beautiful, uniform appearance (black l anchor bolt).
Low processing temperature, no risk of hydrogen embrittlement.
No impact on part dimensional accuracy (extremely thin coating).
Disadvantages and precautions of black l shaped anchor:
Extremely poor corrosion resistance: They should never be used outdoors, in wet environments, in contact with chemicals, or in any corrosive environment.
Reliance on secondary protection: Their rust prevention capabilities are heavily dependent on the quality of the subsequent oil impregnation. Once the oil film fails, rust will immediately begin to form.
Poor wear resistance: During installation and tightening, wrenches can easily wear away the oxide film and oil film on the surface, causing rust to form first at the stress points.
Not a “permanent” corrosion protection solution: They only provide short-term, primary protection.
