The powerful self-locking effect is intrinsic

To create a powerful Self Tapping Screws Manufacturers that offers a secure fastening solution for extreme vibration environments, the Hardlock nut utilises the wedge locking principle.”

Staytite has also created a dedicated Hardlock website, so that customers can find out all they need to know about the capabilities of the Hardlock range.

The Hardlock solution is to use two nuts to play the roles of the hammer and wedge respectively. A small eccentricity in the sliding part of the convex top of the lower nut acts as the wedge.

The result is a gap being created, which is a tightening margin used to provide the self-locking effect. “We already have a distributor in Italy, but we are looking for further partners that are able to promote Hardlock nut, sell it and specify it. At this time, the powerful self-locking effect is intrinsic regardless of whether or not there are any gaps between the upper and lower nuts, which means the user can rest assured that the nut is securely tightened (Figure 5).”
