Self-tapping threaded inserts for making high-strength, wear-free, vibration resistant screw connections in materials with low shear strength such as aluminium and aluminium alloys, brass, bronze, cast iron, duro and thermoplastics. The threaded inserts are tapered at the bottom and have a cutting slot. By screwing in they cut their own threads inside a receiver hole. This guarantees a completely secure and firm anchoring in the host material. Internal thread D1 acc. to ISO 6H. The threaded inserts with cutting slot spring slightly inwards in the slot region in some materials. This results in a screw locking effect. If this is not desired, we recommend the threaded inserts with a cutting bore.

Corrosorber Liquid is a powerful corrosion inhibitor from Cortec. This VpCI® formula protects various metals (ferrous & non-ferrous) from corrosion in many industrial settings.It forms a molecular barrier against moisture, oxygen, and pollutants, preventing corrosion.VpCI® vapours reach all metal surfaces, including hard-to-reach areas, offering comprehensive protection. Suitable for steel, cast iron, copper, brass, aluminium, and galvanised steel, it combats uniform corrosion, pitting, stress cracking, and galvanic corrosion.Protects for up to 2 years indoors.Ideal for equipment preservation, short-term protection during manufacturing, warehouse storage, coastal environments, and protecting valuable items. Easy to apply (dip, spray, or emitter pads), dries to a clear, non-toxic film.Proven effective in tests, outperforming traditional inhibitors.Environmentally friendly, non-flammable, and VOC-free. Made in USA by Cortec, a leader in corrosion control.

Cortec VpCI® 105 Emitters offer superior, long-term corrosion protection for ferrous and non-ferrous metals within enclosed spaces. These innovative emitters harness Cortec's patented VpCI® technology, releasing a vapor that forms an invisible, protective layer on metal surfaces.The unique breathable membrane allows gradual vapor release while blocking contaminants, ensuring consistent protection for up to 24 months.Ideal for various metals including steel, cast iron, copper, brass, aluminium, and silver, VpCI® 105 emitters shield against moisture, oxygen, salts, and pollutants. Simple to use, they require no preparation and offer flexible protection for components, tools, and equipment during storage or shipment.Compared to traditional VCI products, the breathable membrane keeps protected metals cleaner and extends protection duration, reducing replacement needs.

Protect your valuable metals with Cortec VpCI-126 Gusset Bags. These bags utilise Cortec's patented VpCI technology, releasing corrosion-inhibiting vapours that form a protective layer on metal surfaces. Unlike traditional methods, VpCI vapours reach all areas, including hard-to-access spots, providing long-lasting protection without direct contact.The unique gusset design allows for flexible packaging, accommodating bulky items and offering superior strength.Manufactured with a high-quality, multi-layer film, these bags create a barrier against environmental factors, safeguarding metals from rust, tarnish, corrosion, and more. Suitable for various metals, including steel, stainless steel, copper, brass, aluminium, cast iron, silver, and zinc, the bags protect individual parts, components, tools, equipment, and assemblies during shipping, storage, or idle periods.

Cortec VpCI® 369 is a top-tier, easy-to-use coating safeguarding outdoor metal equipment and structures. Leveraging Cortec's advanced Vapor phase Corrosion Inhibitors (VpCI®), this versatile coating defends multiple metals with a single product.VpCI® molecules, vaporising from the coating and condensing on metal surfaces, create an invisible, self-renewing protective layer.This combat corrosion in all forms, from galvanic to atmospheric and salt spray.Protecting steel, cast iron, copper, brass, aluminium, and galvanised steel, VpCI® 369 is ideal for diverse outdoor applications, from heavy machinery to storage tanks. Engineered for harsh outdoor conditions, this tough, flexible coating resists moisture, UV rays, and weathering.Applicable on both new and rusted surfaces, it forms a durable anti-corrosion barrier.Unlike traditional coatings, no rust removal or extensive prep is needed, making it efficient and cost-effective.
