The fastening and opening of bolts and nuts adopts non-standard design, and the matching
non-standard tools are used to solve the opening and fastening problems. In general, other
wrenches cannot be inserted. In the appearance design of nuts and bolts, non-standard slotting,
opening or pentagonal, heptagonal, nine-corner or custom-made corresponding groove tools
have played a very good anti-theft effect

Hexagon Flange Nylon Locking Nuts (also called flanged nyloc nuts) are a type of self-locking fastener designed to prevent loosening under vibration and dynamic loads. They combine a hexagonal head, an integrated flange, and a nylon insert to ensure a secure, vibration-resistant connection without requiring additional washers or adhesives.
Key Features & Design
-
Hexagonal Head (6-Sided)
-
Allows for easy tightening/loosening with standard wrenches or sockets.
-
Available in standard (ISO, DIN, ANSI) and metric sizes (e.g., M4, M6, M8).
-
-
Flange Base
-
A wide, circular flange acts as an integrated washer, distributing clamping force evenly.
-
Protects the mounting surface from damage and improves grip.
-
Eliminates the need for a separate flat washer.
-
-
Nylon Insert (Nyloc Feature)
-
A nylon-6,6 ring embedded at the top of the nut deforms when threaded onto a bolt.
-
Creates friction resistance, preventing loosening from vibration.
-
Typically colored blue (sometimes white or natural).

Material & Coatings
-
Nut Body: Carbon steel (Grade 8/10), stainless steel (A2/A4), or brass.
-
Surface Treatment: Zinc-plated (yellow/silver), black oxide, or galvanized for corrosion resistance.
-
-
Thread Types
-
Metric (coarse/fine) or imperial (UNC/UNF).
-
Common Applications
-
自動車 (engine mounts, suspension, wheel hubs)
-
Industrial machinery (conveyors, motors, pumps)
