Features of the HARDLOCK Set Screw
- Self-Locking Effect
The HLS easily clears US National Aerospace Standard vibration impact test.
Using a single hexagonal wrench it is easy to tighten the fixing screw and lock screw.
- Weather Resistance
Possessing excellent heat and cold resistance, the HLS maintains its self-locking power even in unusually harsh environments.
The HLS can be repeatedly removed and installed without compromising its self-locking effect.
Because it doesn’t require maintenance, the HLS represents a remarkable reduction in total lifetime costs compared with conventional set screws.
- ♦ Standard (socket) type
- ♦ Through type
- ♦ Spacing rod type
The powerful self-locking effect inherent in the HARDLOCK Set Screw is a product of the wedge principle that results from the HARDLOCK eccentric structure. The HLS’s locking performance is unaffected by the external impact and vibration, allowing it to maintain permanent stability.
Vibration Impact Test
The HLS performs well in screw looseness testing using excitation testing equipment, demonstrating a powerful locking effect. * The testing machine was manufactured by HARDLOCK Industry in conformance with the US NAS3350-3354 aerospace standard.
Using a single ordinary hexagonal wrench, a series of simple work steps can be carried out to ensure a powerful locking effect by tightening the concave fixing screw and the convex lock screw. And since the HLS is an all-metallic product with a simple structure, it is easy to remove and capable of repeated reuse.
Overall Cost Cutting Effect
In making comparisons between the HLS and conventional fixing screws, factors such as the need for post-installation maintenance, costs stemming from subsequent loosening and inspecting difficult to reach places must be taken into account. When using the HLS, there is no need to consider these problems, which adds up to a significant reduction in overall costs.
