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

Hexagonal Nylon Lock Nuts (commonly called Nyloc nuts) are a type of self-locking nut designed to resist loosening caused by vibration, shock, and dynamic loads. They feature a hexagonal head for tool engagement and a nylon insert that creates friction against the bolt threads, ensuring a secure, long-lasting connection.

Key Features & Design

1. Hexagonal Head (6-Sided)

   • Standard wrench/socket compatibility (e.g., ISO, DIN, ANSI standards).

   • Available in metric (M3, M5, M6, etc.) and imperial (UNC/UNF) thread sizes.

2. Nylon Insert (Locking Mechanism)

   • A nylon-6,6 ring (usually blue or white) is crimped into the top of the nut.

   • When threaded onto a bolt, the nylon deforms, creating frictional resistance to prevent loosening.

   • Effective up to ~120°C (250°F); degrades at higher temperatures.

3. Material & Finishes

   • Nut Body: Carbon steel (Grade 5/8), stainless steel (A2/A4), or brass.

   • Coatings: Zinc-plated (corrosion-resistant), black oxide, or plain.

4. Thread Types

   • Coarse (standard) or fine threads, depending on application needs.

Common Applications

• 自動車 (engine components, suspension, brackets)

• Industrial equipment (pumps, motors, conveyors)

• Electronics & appliances (PCBs, housings)

• Furniture & DIY projects (where vibration is a concern)

Standards & Specifications

• DIN 985 (Metric nylon insert lock nuts)

• ISO 7040 (Prevailing torque type, non-metallic insert)

• ASME B18.16.3M (Metric series lock nuts)

Installation Tips

• Do not over-tighten – Excessive torque can damage the nylon insert.

• Avoid lubricants on threads – Reduces locking effectiveness.

• Check for wear – Replace if the nylon appears cracked or flattened.
