Product Features Each of the male inserts retains the basic design and installation features of the female version. Headed, Unheaded, Short, Regular and Long can all be produced. Definitions Head End – The profile of the fastening end of the male insert that is fixed into the parent material. Head Length – Normally the overall length of the equivalent female fastener. Overall Male Thread Length – The overall length of the male insert less the head length. This may incorporate special ends to the thread to assist in location of the nut or other customer design requirements. Plain Portion – There is a run out between the commencement of the thread and the shoulder of the head profile, which is generally restricted in length. Nut End Length (NEL) – This defines the maximum distance from the commencement of the chamfer at the end of the thread to the head profile and incorporates the plain portion. Design Aids For a suitable post installation application cold pressed male Multisert® are the quickest to install and thus most economic whilst providing high pull out performance. If greater pull out performance is required then a male-Trisert design can be specified. Ultimate performance can normally be achieved with a male-HiMould® design being moulded into the parent material, can be used if suitable for processing. Having decided on the most suitable method of installation and therefore head end design, the overall male thread length and nut end length (if different) should be defined.
