Black M3-M12 Stainless Steel A2 Bolt-Cup Square Head Screw

1. Ordinary bolts
Ordinary bolts are the most common type of bolts. They are mainly used to fix light-loaded components, such as fixed bases, bearings and other components. Ordinary bolts are divided into two types: Grade A and Grade B. Grade A bolts are suitable for general occasions, and Grade B bolts are suitable for fastening occasions with higher requirements. In construction elevators, ordinary bolts can be used to fix light-load structures, such as motor seats. wait.
2. High strength bolts
High-strength bolts are widely used in engineering machinery, bridges, wind power equipment and other fields due to their greater strength and better reliability. In construction elevators, high-strength bolts can be used to fix heavy-load components, such as top floor bases, guide rails, etc.
3. Anti-loosening bolts
An anti-loosening bolt is a bolt that can effectively prevent loosening by adding a spring washer between the bolt head and the washer to make the bolt less likely to loosen when subjected to vibration. In construction elevators, anti-loosening bolts can be used to secure easily loose components, such as brakes
Shopping advice:
When selecting bolts, factors such as the strength, material, and length of the bolt should be considered based on actual needs. High-strength bolts should be selected for fasteners that require tensile stress. For fasteners that are easy to loosen, anti-loosening bolts should be selected. At the same time, attention should also be paid to the matching between bolts and nuts. Nuts of different grades cannot be mixed with bolts of different grades.
Summarize:
The classification of construction elevator bolts includes ordinary bolts, high-strength bolts and anti-loosening bolts. Each bolt has different usage scenarios. When selecting, you should choose different types of bolts according to actual needs, and pay attention to the strength, material, length of the bolts, and their matching with the nuts.
