All Metal Locknuts

Click image to enlarge

All metal locknuts, also referred to as self-locking nuts, are known for their unique thread design to “lock” the nut in place after proper installation. These nuts are made entirely of metal with a deformed thread at the top of the nut to grip the bolt, as seen with the divots on top of the nut. All metal locknuts are ideal for applications subject to high vibration, movement and thermal expansion that would fail with a regular hex nut. To select the best locknut for your application, be aware of strength requirements and environmental requirements at hand.

• Class C , All Metal Locknuts: Heavy duty locknut, offering superior hold.
• Metric Class 8 & 10 All Metal Locknuts: Moderate and heavy-duty locknuts, offering superior hold.
• Serrated, Flanged Hex Locknuts: Offer the locking feature with a flanged collar for increased load distribution.
• Reversable Locknuts: Offers increased flexibility to install the locknut from either direction.
• External tooth keps hex locknut: A variation of the locknut, designed to utilize the teeth to engage the surface.
