DIN985 Nylock Nuts – Reliable Locking for High-Vibration Applications

DIN985 nylon-insert lock nuts are designed to maintain strong and secure fastening even under continuous vibration and dynamic loads.
The nylon ring provides additional friction against the bolt thread, preventing loosening and ensuring long-term stability.

Key Functional Advantages：
🔹 Vibration-Resistant Locking – The nylon insert grips the threads tightly, keeping the nut in place even in machinery, vehicles, or moving equipment.
🔹 Reusable to Some Extent – The locking torque remains effective after multiple assemblies (depending on application).
🔹 Prevents Thread Damage – The nylon ring reduces metal-to-metal abrasion, extending the service life of bolts and nuts.
🔹 Corrosion-Resistant Options – Available in carbon steel (zinc plated) and stainless steel A2/A4 for outdoor or marine environments.
🔹 Wide Range of Applications – Widely used in construction, automotive, home appliances, equipment manufacturing, and metal structures.

What Do A2-70, A4-70, and A4-80 Mean in Stainless Steel Fasteners?

If you’ve ever looked at stainless steel bolts or nuts, you’ve probably seen marks like A2-70, A4-70, or A4-80 stamped on the head — but what do they actually mean?

Let’s break it down

✅ A2 – refers to stainless steel type 304, the most common grade used in fasteners. It provides good corrosion resistance and is suitable for most outdoor and industrial applications.

✅ A4 – means stainless steel type 316, which contains molybdenum for better resistance to salt, acid, and marine environments — perfect for coastal or chemical use.

✅ The number (70 / 80) – indicates the strength class.
• 70 = 700 MPa tensile strength
• 80 = 800 MPa tensile strength

In short:
🔹 A2-70 → 304 stainless, standard strength, great all-rounder.
🔹 A4-70 → 316 stainless, for tougher environments.
🔹 A4-80 → 316 stainless with higher strength, used in demanding conditions.

🔩 Can you spot the difference between these 2 stainless steel 410 self-drilling screws?

The answer is their thread design, which makes a huge difference in performance.

✅ Fine Thread
• Best for thin steel plates and metal-to-metal fastening
• Provides stronger holding power in harder materials
• Better resistance to vibration loosening

✅ Coarse Thread
• Perfect for wood, softer materials, or thick sheet metal
• Faster drilling and installation
• Stronger grip in soft substrates
• Less likely to damage weaker materials

✨ At TY TIGHT, we supply both fine and coarse thread self-drilling screws, helping you choose the right solution for your project.
