In-line with our philosophy of continuous product development, Tappex has introduced a new material to the proven Trisert-3 range made from Titanium Grade 5, this option opens up opportunities for applications in particularly harsh environments or corrosive atmospheres, and where weight is of prime importance. Titanium has three key properties that make it particularly desirable: 1. High level of corrosion resistance. 3. High strength (950 MPa). The Trisert-3 Titanium retains all the advantages of the existing Trisert-3 range: • three facets offering balanced cutting • enhanced back-out performance • large bearing surface - the reduced head also aids orientation of the insert • speed of installation • free running internal thread • compatibility with the existing Trisert / Trisert-3 hole sizes • reduced external diameter • fully supported cutting edges. • no contaminating flitter Titanium Grade 5 is an alloy of Titanium offering high strength, light weight and excellent corrosion resistance. When Titanium is exposed to atmosphere, a stable, substantially inert, oxide film is immediately formed. It is this surface film that gives the material its excellent corrosion resistance. Titanium does not corrode in normal seawater environments, or polluted waters such as ports and harbours. ©Tappex Thread Inserts Ltd 2018. All Rights Reserved

Titanium has a high strength to weight ratio and a much lower density, approx. 50% lower than 316 stainless steel, for example. The part number is defined as per the Trisert-3 range, with regular 6238 and long 6270 lengths as standard, followed by the thread size, and material designation defined as -Ti5. Specials, Imperial threads, Headed and Blind variants would be considered; please contact our Engineering Department with your requirements.
