Nut Inserts

Our premium nut inserts deliver strong, dependable threads in thin or soft materials—perfect for metal fabrication, automotive, furniture, electronics, and more. Available in steel, stainless steel, and aluminium, our inserts provide the right balance of strength, corrosion resistance, and lightweight performance for any application.
Choose from round or hex body styles to ensure superior grip and resistance to spin-out, even under demanding loads. Engineered for fast, consistent installation, our nut inserts help you achieve professional, high‑integrity fastening every time.
Upgrade your assembly quality with nut inserts built for precision, durability, and versatility.

Nut Inserts

Nut inserts, rivnuts, nutserts, no matter what you call them offer exceptional strength and durability, making them ideal for applications where high pull‑out and torque resistance are essential. Their robust construction ensures reliable threads in thin metals and other materials that cannot support traditional tapping. Nut inserts are a cost‑effective solution for heavy‑duty fastening and are commonly used in industrial fabrication, machinery, automotive components, and structural assemblies.
Available in round and hex body styles, Nut inserts provide excellent spin‑out resistance and secure, long‑lasting performance even under demanding loads. For applications requiring maximum mechanical strength at an economical price point, nut inserts are the go‑to choice. Available in Steel, Aluminium, Stainless Steel.

Plus Nuts

Plus nuts are engineered to provide exceptional holding power in thin, brittle, or oversized holes where traditional rivet nuts may struggle. As they expand into four large folding legs during installation, plus nuts create a wide, secure backside footprint—delivering superior pull‑out resistance and load distribution.
Ideal for van fit‑outs, racking, plastics, composites, and sheet metal, plus nuts offer reliable fastening even in materials that can’t support standard threaded inserts. Their large expansion makes them perfect for irregular or worn holes, ensuring a tight, dependable fit every time.
Easy to install and compatible with a wide range of bolts and thread sizes, plus nuts are the go‑to solution when you need a strong, adaptable fastening method in challenging conditions.

Rubber Nuts

Rubber nuts (also known as well nuts) provide a unique combination of fastening strength, vibration isolation, and sealing capability—making them ideal for applications where traditional metal inserts may cause noise, wear, or leaks. During installation, the rubber body expands to create a secure anchor behind the material, while also forming a tight seal against moisture, dust, and air movement.
Perfect for sheet metal, plastics, fiberglass, and other thin or delicate materials, rubber nuts excel in automotive, HVAC, marine, and electronics applications where vibration damping and leak prevention are essential. Their simple installation—requiring only access from one side—makes them an efficient, reliable choice for a wide variety of assemblies.
When you need fastening plus noise reduction and environmental sealing in a single component, rubber nuts deliver unmatched versatility and performance.
