Deform-Ti® – when resistance is lightweight 02 April 2019

Specialinsert® has introduced Deform-Ti® – a threaded tubular rivet fully made of titanium alloy and designed for installation on sheet metal and composite panels.

Due to Specialinsert®’s research and development oriented business strategy, Deform-Ti® emerges from the evolution of one of Specialinsert’s leading products – Deform-Nut – the threaded tubular rivet made of steel, stainless steel and light alloy.

With Deform-Ti, the company is introducing a solution able to meet the most stringent industry standards where weight control is as important as the materials’ mechanical strength capacity. Technical laboratory tests on the TC M6/TZ insert demonstrates that the titanium alloy rivet (2.1g/pc) weighs 40% less than a stainless steel one (3.7g/pc) and is able to withstand a tensile strength of 25,800N, 27.8Nm torsion and 6,450N shear strength. Specialinsert points out that these features, combined with high rust resistance, ensure Deform-Ti’s excellent performance, making it the first choice as a partner for the automotive, nautical and chemical industries.

Ideal for applications where there is no possible access from the inside, such as tubes, metal sheets, and box structures, this system is easy and quick to apply. In fact, the user simply inserts Deform-Ti in the created hole on the material to be fastened and then uses the specific installation tool on the rivet – deforming the expansion chamber at the top of the insert and anchoring it to the receiving material. Another plus of Deform-Ti is its extreme versatility. It can be mounted on any type of composite material, starting from a minimum of 0.5mm, and on finished parts to be used in any production process phase – guaranteeing the utmost design freedom.

Available in a cylinder version with different shaped heads, with the most popular threading, the titanium alloy rivet, like other Specialinsert ranges, can be customised according to customer needs, guided step-by-step in the choice and development of the right fastening system for any application by a team of in-house specialists.
