INSERT TECHNOLOGY FOR PLASTICS COMPOSITES AND METAL ALLOYS 50 YEARS OF FASTENER INNOVATION

50 YEARS OF INNOVATION Tappex Thread Inserts Limited was incorporated in September 1956 by its founder the late Mr. Derrick Barnsdale. From very humble beginnings in a reclaimed cow shed on Masons Road in Stratford-upon-Avon the company flourished and grew into the modern purpose built manufacturing plant it resides in today, on the original site. With over 50 years’ experience in the design, development and manufacture of threaded inserts for plastics, the company, now led by his son Tim Barnsdale, is one of the UK’s most successful privately owned specialist fastener manufacturing...

TRISERT® DOUBLE ENDED REDUCED HEADED REGULAR HEADED ADVANCED In line with our philosophy of continuous product development, Tappex have expanded the range of Trisert selftapping inserts, which have the unique feature of enabling cold installation into most grades of plastic and composite materials. The range includes three primary designs: Double Ended, Reduced Headed and Regular Headed variants, to solve most application problems in thermoset and thermoplastic grades including the latest engineering plastic alloys. The concept of the Trisert design is to provide a reliable and efficient...

DOUBLE ENDED A self-tapping, double ended insert available in short, regular and long lengths in a range of thread sizes from M2 to M10. HOLE DESIGN Product Features The Double Ended Trisert has a lead on both ends significantly simplifying the installation process and requiring less operator skill. The combination of the three cutting flutes and the coarse external thread form increases the radial and pull-out performance making the Double Ended Trisert ideal for use in thermoplastics where there is a gap, or gasket or ‘O’ ring, between the mating parts. It can also be used in a...

REDUCED / REGULAR HEADED Self-tapping, headed inserts available in regular and long lengths in a range of thread sizes from M2.5 to M10. INSERT DESIGN Product Features The Reduced and Regular Headed Triserts allow greater tightening torques because of their increased bearing surface, which also provide more support to softer mating components. The difference in head diameters are designed to give the optimum cost effective solution for a particular application. The larger Regular Headed versions are particularly suitable where there is a large or slotted clearance hole in the mating...

TRISERT® ADVANCED The unique Trisert self-tapping range of inserts is also available in an advanced engineered range for critical plastics and all thermoset materials . Advanced Features The closely controlled external thread allows effective cutting in hard urea, melamine and phenolic materials without cracking or moulding damage. The unique cutting form combined with the perfect symmetry of design significantly improves the performance of the insert in hard The Trisert, with its solid cylindrical design provides significant cost savings allowing a brass insert to be used in critical...

The standard Trisert range has for many years included three primary designs, Double Ended, Reduced Headed and Regular Headed variants. These solve most application problems in thermoset and thermoplastic grades, including the latest engineering plastics. The concept of the Trisert design is to provide a reliable and efficient post-mould process, where the installation torque can be controlled and monitored for greater reliability. As the internal thread is used to install the Trisert, every insert is therefore automatically checked in the moulding for the existence of a good thread....

TRISERT-3 REDUCED HEADED The concept of the Trisert-3 design is to provide a reliable, strong and wear resistant thread in applications, environments and materials that would be unsuitable for brass inserts. Product Features The design combines three cutting facets with three shallow flutes offering balanced cutting and enhanced back out performance. The internal thread is not interrupted by cutting features and therefore will guarantee a free running internal thread without the risk of swarf jamming the screw. The Steel variant is case hardened and is offered with a zinc nickel trivalent...

TRISERT-3 REDUCED HEADED Due to the various mechanical characteristics, a precise hole size specification is imperative. INSERT DESIGN A minimum hole depth of 1.2 x the insert length would normally be specified, with the insert installed to a maximum of 0.3mm sub flush to the surface. Stainless steel threaded fasteners generally should not be assembled using very high speed equipment, as mating surfaces will be subject to galling and may cold-weld together leaving a falsely tightened joint. It is therefore recommended that when a stainless steel screw is assembled to a stainless steel...

Product Features With the same external features as the standard Trisert-3 the blind ended version is supplied with a closed end. INSERT DESIGN Self-tapping, reduced headed, blind ended, stainless steel inserts available in regular and long lengths in thread size M10. Offered in M10 and Stainless Steel only, other thread sizes will be considered when requested.
