Features of HugBolt
1）Efficient workable 2-piece structure
D-Lock is simple 2-piece structure that combines/assembles functional accessories beforehand, enhancing on-site workability. This can prevent the accessories from dropping、losing or being forgotten to be assembled and to ensure safe and secure working place.
2）High detent effect
The means of detent generally is a method of using spring washer or double nut While based on the result of performance comparison via using a screw loose tester, we have decided to adopt disc spring that is expected to provide high effects in a more steady manner.
3）Response to compliance
In response to society with compliance strictly observed, we are ready to provide traceability including set-specific lot control, submission of performance table and offer of production control information. You can check axial shear force which is one of the most frequently asked questions in recent days as we test 100% lots and provide the results in the performance table.
