Hard Lock Nuts Can Be Extremely Useful

By Lucia Weeks


Utilizing the wedge principle to form a strong self-locking structure is the purpose of (HL units). These are also known as hard lock nuts. A wedge forced into the space between a cylinder and the tube that surrounds it creates an assembly that locks forcefully. If this effect is achieved by matching grooves in the nut and bolt, a wedge can be hammered in but leaves the assembly difficult to operate.

From the perspective of ease of use, it can be more advantageous to apply an assembly of concave and convex shapes instead of applying brute force with hammers and wedges. Tightening this set of nuts brings about the same outcomes as coercing a wedge into place by pounding. The utilization of threaded screws means it is straightforward to accurately and securely situate the wedge.

Self-locking ones work in pairs. The bottom nut is tightened first, followed by the upper one. Installing the top nut by hand creates a tightening margin. The intrinsic self-locking outcome is brought into play by the torque created when using a wrench to turn the top nut.

The evolution of this brand of nut had the intention of ending the nuisance of damaged bolts and slack screws. This style of formation has the benefit of averting any shortfall in axial force ensuing as a result of metal fatigue. Traditional Japanese architecture motivated the fabrication of a wedge-shaped, double nut assembly to economically eliminate the drawback of slackness in screws as well as creating enhanced workability.

Certainty and trust are established by the confidence that HL units never acquire dangerous play. No ends of studies about screw looseness have demonstrated this kind of nut's superiority in safeguarding the primary tightening strength. Appraisals carried out on the job by construction industry workers have verified that using these pioneering nuts instead of old-fashioned kinds significantly lowers overheads in terms of man-hours. One further substantial plus is the knowledge that HL units provide enhanced security, preventing erection firms from coping with lawsuits launched because of industrial accidents following-on from sheared-off bolts or screws becoming loose.

There are various situations where this mechanism alone has been confirmed to be acceptable. One such condition is the existence of relentless external powers applied in a very similar rotational path as a bolt, or straight up from the bolts, or perpendicular relative to bolts. Another case in point is when pulsations are constantly present. Severe variability of temperature is one more capacity of these devices.

HL units create a seal comparable to riveting, adhesive bonding or welding. Unlike these fixings, HL units can be easily removed for servicing or maintenance. As the self-tightening performance does not deteriorate over time, HL units can be re-used time after time.

A world-leading producer of lock nuts comes in the shape of the Hardlock Industry Co., Ltd. Their gadgets have endorsements for aerospace purposes in prestigious projects such as the Kansai International Airport. Some of the most significant US aerospace international businesses including Boeing avail themselves of HL units thanks to their guaranteed security. The Olympic bobsleigh of the Japanese team employs extraordinary HL units fashioned from titanium for lightness.
