Nylock and Prevailing-Torque Lock Nuts
Lock nuts use a nylon insert, deformed all-metal section, flange or locking insert to create prevailing torque in the threaded assembly. Bhartee Industries keeps each mechanism as a distinct product choice so functionally different nuts do not become ambiguous lines in the same RFQ.

TYPE SELECTION
Choose the locking mechanism deliberately
The joint environment, assembly method, service conditions and governing specification determine which lock-nut design is appropriate. Do not substitute one locking mechanism for another without technical approval.
Flange Nylock Nuts
Nylon-insert nuts with serrated or non-serrated flange variants recorded as separate lines.
All-metal Lock Nuts
Steel-insert flange and prevailing-torque designs where an all-metal mechanism is specified.
DIMENSION RULE
Nut height follows the selected product standard
No overall-length field is shown for the approved lock-nut families. Buyers enter thread diameter, pitch, material or property class, finish and quantity. Variant fields appear only when serrated, non-serrated, top-lock or centre-lock choices are technically distinct.
MATERIAL AND FINISH
Keep the lock nut compatible with its mating fastener
Material, class, thread and finish should be reviewed with the mating bolt or screw. Stainless-steel selections do not ask for a separate finish, while steel options expose approved coating choices and Other / Custom.
RECOMMENDATIONS
Add only the appropriate mating hardware
Nylock Nuts can suggest a compatible Hex Head Bolt and Plain / Flat Washer. Flange and all-metal variants keep recommendations narrower because washer use and flange function depend on the specific joint design.
BUYER QUESTIONS
Frequently asked questions
Are DIN 985 and DIN 982 Nylock Nuts the same height?
No. They identify different standard forms, including different nut-height configurations. Select the required standard rather than treating them as interchangeable.
Should serrated and non-serrated flange lock nuts be separate lines?
Yes. They have different bearing and locking behavior, so the inquiry keeps serrated and non-serrated variants as separate specifications.
Are lock nuts requested in Pieces or Kg?
The approved lock-nut products are currently requested in Pieces only.
