If so, then an Auto-lok nut could be the perfect solution. Auto-lok nuts are self-locking nuts that provide extra security when securing bolts and screws. They are designed with a unique self locking feature which prevents them from loosening or coming undone due to vibration or shock.

Auto-lok nuts have several advantages over traditional locknuts such as being easier to install and providing greater resistance against vibrations. In addition, they can also be used in applications where high levels of torque must be applied without fear of loosening the nut during operation. This makes them ideal for use in industrial machinery where precise adjustment is required but regular maintenance may not always take place on time or at all !

The Auto-lok Turret slots are aligned radially, one above the other. This design increases the strength and durability of the nut type and helps to reduce risk of failure due to fracture between base slots. The Auto-Lok nut type is designed with this radial alignment in mind, which appears to decrease any potential for fracturing or loosening that may be a limitation of Industrial types.

Overall then this type fastener provides superior performance compared more traditional methods like locknuts – offering increased reliability & safety through their self-locking feature plus ease installation all same time – making one great choice anyone needing reliable bolt/screw connections today!

Auto-Lok nuts are available in A2, A4, Grade 8, 10 and 12 materials, great variety to choose whichever material best fits your application needs while still maintaining superior locking performance over traditional industrial types. Additionally, they feature a reduced diameter top which provides an increased grip on fasteners as well as improved torque transmission during installation/removal operations making them ideal for many applications such as automotive assemblies or construction projects where reliable joint integrity is critical.

The main differences between GEOMET 500A and GEOMET 500B are in the type of lubricant and in their corrosion resistance.

- Geomet 500A    mineral oil based lubricant

- Geomet 500B     synthetic oil based lubricant (advantage: higher level of lubricity and better adhesion to the nut)

GEOMET 500A has a corrosion resistance of 600 hours or greater, while GEOMET 500B has a corrosion resistance of 1000 hours or greater.

Both coatings are zinc-aluminium flake coatings, but the 500B has a thicker layer and is more resistant to corrosion. Additionally, GEOMET 500A is available in a variety of colors sometimes, while GEOMET 500B is generally only available in silver.

Yes, the H&C Parts are double-slotted turret nuts class CL8.

The dual-lock self-lock nut is zinc passivated.

Auto-Lok nut recommends switching over to the class 8 Auto-Lok nut yellow plated.

It's Zinc & Yellow RoHS

We supply many of our stainless steel Auto-Lok nuts in a choice of two grades A2 and A4

A2 Version refers to V2A also known as 1.4301 or AISI 304

A4 Version refers to V4A also known as 1.4404 or AISI 316L

There are different grades of stainless steel. This means that under normal conditions, these types of steel are corrosion resistant.

Both :

- Offer excellent levels of corrosion resistance 

- Renowned for their durability and sustainability

The self-locking Auto-lok nuts have different mechanism to avoid loosen.

The different  mechanism of self-locking resists vibrations and  and create a self-locking feature in the Auto-lok nuts.

The  action of ALNvsr -  Vertical slotted ring self-locking Auto-lok nut is the spring ring tightens the tapping diameter at the slots of the nut body.

The engagement of the screw in the upper part of the nut moves the split parts of the nut body apart. By reaction, the spring ring creates a pressure that generates a tightening torque immobilizing the nut on the thread of the screw.

Some advantages

The ALNhsr - horizontal slotted ring self-locking Auto-lok nut is manufactured with a stainless steel spring insert. As the nut is fixed on the screw thread, the stainless steel spring insert secures with the base of the screw thread and expands upwards. This gives the nut a lower installation torque compared to other types of self-locking nut, especially those of the deformed thread type.

The ALNhsr - horizontal slotted ring self-locking Auto-lok Nut withstands vibration and loosening since the insert moves downwards and is ‘pulled’ into closer contact with the screw thread by the upwards anti-clockwise rotation of the nut body. This also gives a very effective interfering fit between the threads of the nut and of the screw. 

What is the difference between an Auto-Lok nut and the part number I requested?

The requested part and suggested alternative Auto-lok nut part number will be fully interchangeable with the thread. Since every part number is different, and you might have enquired for a discontinued or obsolete part, we need to verify with engineering to double check the compatibility.

Your sales rep can give you full confirmation about following properties of the part:

• Form
• Fit
• Functionality
• Material and Finish
• Made according to the same quality and standard
• Guaranteed same prevailing torque
• Identical corrosion resistance

Please contact us for additional information or a quote.

The self locking Auto-Lok Nut can be assembled with the locking element leading onto the male thread.

The self locking Auto-Lok nuts are reusables.

The auto lok-nuts combine both extreme vibration resistance with re-usability so you can rely on them time and time again.

The reusability will vary depending on the type auto lok nut type, the application and the use.

The Auto Lok nut is Re-usable up to 5 times with no performance loss according to ISO2320.

You can re-use them up to 15 times, ideal for maintenance purposes.
