Popular Types of Nuts We Stock

🔩 DIN 985 – Nylon Insert Lock Nut
Also known as a “nyloc” nut, the DIN 985 is a self-locking nut that features a nylon insert to prevent loosening under vibration. It’s ideal for:
- Automotive applications
- Machinery assemblies
- High-vibration environments
Available in:
Zinc-plated, stainless steel, A2 & A4 grades
Sizes: M3 to M48 and beyond

🔩 DIN 934 – Hex Nut
The DIN 934 is a standard hexagonal nut, commonly used in general-purpose fastening. It’s a go-to option for most engineering and construction tasks.
Available in:
Steel, stainless, brass, and other finishes
Sizes: Wide range in metric and imperial
🔩 DIN 982 – All-Metal Lock Nut
Unlike the nylon insert of the DIN 985, the DIN 982 is an all-metal lock nut, offering superior temperature and chemical resistance.
Perfect for:
- High-heat environments
- Heavy-duty applications
- Outdoor use
🔩 DIN 439 – Thin Hex Nut (Jam Nut)
A thinner alternative to the DIN 934, used as a locking jam nut against a standard nut. Great for tight spaces or for added security in bolted assemblies.

🔩 Cap Nuts (DIN 1587)
These dome-shaped nuts protect threads and offer a clean, finished look. Common in decorative or safety-critical installations.
🔩 Wing Nuts, Square Nuts, Castle Nuts, T-Nuts, and More
